Cars & Coffee, Hot Rods and a Fuel Leak


Jeff Detwiler
 

Hi All,

I could use a little sage mechanic advice.
It's been a long time since I really did much of my own wrench-turning.

I was out today for Cars & Coffee in Skippack.
Thanks, Noel, for setting it up.
It was a good flight test and my MG ran like a top (no complaints).

Ah, actually, maybe one, it's getting to that time of the year when high 90's
are not much FUN sitting in traffic at red lights (if you know what I mean)?
FYI - not a C&C complaint, just Mother Nature.....

Anyway, after Cars & Coffee, I schlepped over to Towamencin for some family 
business.  On my route home I was going to drive me right past "The Landing" 
retirement campus where I was told there would be a Community Car Show 
and picnic for the residents and local neighborhood.

So, I pulled in to take a peek, but was ushered to a parking spot.  Oh No!!
As usual for many of these car events without a British focus, I was the only 
British car among the American and Muscle Hod Rods.  But it was nice to chat 
with a few old-timers who either stopped to tell me how they had a MG (or Triumph, 
Healey, etc) in their day. Or many simply appreciated how tiny the car was compared
to all of the other bigger Hot Rods nearby or just the "pretty" color.
I too am still tickled about the 1978 Pagent Blue Abingdon used that year.

Anyway, I'm a little off from needing Mechanic advice as yet.
So, I drive home in the hot of the day and all is well (75 mile RT).
I stop at my local gas station to fill-up and proceed home, pull into the driveway
and begin to unload and few items.  I open the rear trunk lid (i.e. boot) and smell fuel.

I pull a few items out to dig deeper and discover and few puddles of fuel laying in the 
trunk well.  When I filled-up I did top the tank but not to overflowing the cap onto the 
rear bumper.  My first thought was my fuel tube from filler to trunk deck is leaking or
the wire clamp needs to be tightened (doesn't appear to be).  Then I spied a little metal
tube and nut emerging up from the trunk deck that appears to have simply been sawed off.

Looking at the Moss motors diagrams I seem to remember some Emissions equipment may 
have been back there originally.  I know my Emissions Air Pump and may bits and pieces were
removed back in the 80's.  My guess is this could have been this way for a long time as it 
appears on the diagrams to go to a Vapor Separator which also is not currently installed.

So is this little cut-off tube acting as a Vent?
Could I have over-filled the fuel tank enough to have been dumping fuel into the trunk?
Could this be why during the winter months went the car seldom goes anywhere I 
every-so-often get a whiff of gas in the trunk?
Should I plug/cap this or does it need to be there, is there some other correction I may need to consider?
I'm not the greatest wrench-turner these days so you can't crush my ego.

Thanks for any and all input.

Jim, without seeing what you’re talking about, my guess is that you’re talking about the tube that’s supposed to go from the the tank vent to the carbon (charcoal) emissions  canister… which in your case is now missing and was never properly plugged. 

Cheers,
Kevin

Hi Kevin,

I attached a .pdf file with a few photos of the fuel tube to the original message.
At this point, should it simply be capped?

Jeff,

There was indeed a line from that fitting up to a vapor recovery tank which then routed out to the charcoal canisters in the engine compartment. Since it sounds as though the recovery tank was removed, the fitting to the tank needs to be capped. The issue however is that was also a pressure relief for the tank due to temperature changes. The most common solution is to drill a small hole in the gas cap on the side so that you don't see it and so you know longer vent into the trunk space.

I believe there is a thread about venting the gas cap on mgexp.com

Hope this helps.

Mark

Sorry. Things are a bit of a muddle and I likely got confused. 

Jan and I were on a camping trip with our scouts this weekend and in the middle of that we got a call that her 97 yo mom had fallen and broken her hip. Jan had to bug out and I had to pop her on an airplane for Kalamazoo. Then I had to return to the encampment because we needed enough leaders there… So our weekend has been a blur.

Jan and I were on a camping trip with our scouts this weekend and in the middle of that we got a call that her 97 yo mom had fallen and broken her hip. Jan had to bug out and I had to pop her on an airplane for Kalamazoo. Then I had to return to the encampment because we needed enough leaders there… So our weekend has been a blur. 

Cheers,
Kevin

Jeff,

There was indeed a line from that fitting up to a vapor recovery tank which then routed out to the charcoal canisters in the engine compartment. Since it sounds as though the recovery tank was removed, the fitting to the tank needs to be capped. The issue however is that was also a pressure relief for the tank due to temperature changes. The most common solution is to drill a small hole in the gas cap on the side so that you don't see it and so you know longer vent into the trunk space.

I believe there is a thread about venting the gas cap on mgexp.com

Hope this helps.

Mark

Hi Kevin,

I attached a .pdf file with a few photos of the fuel tube to the original message.
At this point, should it simply be capped?

Jim, without seeing what you’re talking about, my guess is that you’re talking about the tube that’s supposed to go from the the tank vent to the carbon (charcoal) emissions  canister… which in your case is now missing and was never properly plugged. 

Cheers,
Kevin

Hi All,

I could use a little sage mechanic advice.
It's been a long time since I really did much of my own wrench-turning.

I was out today for Cars & Coffee in Skippack.
Thanks, Noel, for setting it up.
It was a good flight test and my MG ran like a top (no complaints).

Ah, actually, maybe one, it's getting to that time of the year when high 90's
are not much FUN sitting in traffic at red lights (if you know what I mean)?
FYI - not a C&C complaint, just Mother Nature.....

Anyway, after Cars & Coffee, I schlepped over to Towamencin for some family 
business.  On my route home I was going to drive me right past "The Landing" 
retirement campus where I was told there would be a Community Car Show 
and picnic for the residents and local neighborhood.

So, I pulled in to take a peek, but was ushered to a parking spot.  Oh No!!
As usual for many of these car events without a British focus, I was the only 
British car among the American and Muscle Hod Rods.  But it was nice to chat 
with a few old-timers who either stopped to tell me how they had a MG (or Triumph, 
Healey, etc) in their day. Or many simply appreciated how tiny the car was compared
to all of the other bigger Hot Rods nearby or just the "pretty" color.
I too am still tickled about the 1978 Pagent Blue Abingdon used that year.

Anyway, I'm a little off from needing Mechanic advice as yet.
So, I drive home in the hot of the day and all is well (75 mile RT).
I stop at my local gas station to fill-up and proceed home, pull into the driveway
and begin to unload and few items.  I open the rear trunk lid (i.e. boot) and smell fuel.

I pull a few items out to dig deeper and discover and few puddles of fuel laying in the 
trunk well.  When I filled-up I did top the tank but not to overflowing the cap onto the 
rear bumper.  My first thought was my fuel tube from filler to trunk deck is leaking or
the wire clamp needs to be tightened (doesn't appear to be).  Then I spied a little metal
tube and nut emerging up from the trunk deck that appears to have simply been sawed off.

Looking at the Moss motors diagrams I seem to remember some Emissions equipment may 
have been back there originally.  I know my Emissions Air Pump and may bits and pieces were
removed back in the 80's.  My guess is this could have been this way for a long time as it 
appears on the diagrams to go to a Vapor Separator which also is not currently installed.

So is this little cut-off tube acting as a Vent?
Could I have over-filled the fuel tank enough to have been dumping fuel into the trunk?
Could this be why during the winter months went the car seldom goes anywhere I 
every-so-often get a whiff of gas in the trunk?
Should I plug/cap this or does it need to be there, is there some other correction I may need to consider?
I'm not the greatest wrench-turner these days so you can't crush my ego.

Thanks for any and all input.
Jeff (and The Furry Jedi)

I am not sure what year you have, however here is my experience with my ‘65. 

I would always smell gas when it was parked. Not a strong odor, but enough to tell the smokers at work to stay away when they smoked. 

I ultimately needed a new gas tank because it was slightly perforated. Not enough to see a drip, but enough to let fumes out. 

However on the way to finding that out. I tried all the basic fixes first. I was surprised to learn the getting the fuel from the fuel filler hole to the tank is quite rudimentary. 

There is not a lot to replace. There is a gasket / rubber seal on the outside between the filler hole and bidy sheet metal. There is then a similar rubber seal on the inside.  I don’t remember there being any clamps from the filler hole to the metal bent section that takes the fuel down a couple of inches to the tank. 

In between the metal curved pipe (35 degrees ?) there is a thick rubber section the allows play / imperfections in the angle to continue to the tank. 

There is a clamp holding the metal curved section to the rubber section. I don’t remember (and the schematics don’t show) a clamp between the rubber section an the metal section the is the opening to the tank.

That’s it.  A very basic method of getting fuel from the outside into the tank.

The design is not great if you stuff a lot of items into your trunk. The rubber section. Probably can get pushed / have pressure on it. When rubber sections attach to metal and are bent slightly to the side, then can leak.

If I were you, I would replace the two seals on either side of tgs sheet metal. I would also replace the rubber section.

since you had puddles in the trunk, and it could not be overfilled, slosh out on the outside (plus the is a rubber seal on the cap) and then come in the trunk weatherstripping, I would suspect it is one of two things.  It is also unlikely that there is a hole in the metal section going into the tank  

1. The rubber connector tube has perished / developed a pinprick leak. Or 2. the clamp is loose. 

My money is on the rubber section leaking. Since it occurred after filling the tank full, I suspect that the fuel was up into the rubber hose section / metal bend section. Since it was up there, gravity (and suspicions one or two occurred) it drained out into the trunk. The reason you didn’t have more fuel is because once the fuel level was below the metal and rubber sections, it was only in the tank. 

 These are my best guesses based on my past fuel experiences. 

I would start by replacing the rubber connector section (I doubt it is expensive). I would also replace the two seals on either side of the sheetmetal  (even though this is improbably the cause, if rubber has perished, then this is an inexpensive thing to do, allowing you to eliminate one more thing from the suspicions). 

I would also replace the clamp or at least make sure it is snug (but not over-tightened to the point that the rubber section deforms). It would not hurt to add a clamp on the other end where the rubber section attaches to the tank. 

My thoughts are that if you do all these inexpensive things, you will eliminate the most likely causes.  If they don’t work, you will need to investigate the tank. However since you had puddles instead of just fumes, this is highly unlikely.  

Park it outside or at least leave the garage door open fir now. Gasoline fumes can suffocate you and are highly explosive. Definitely don’t use a lighter to look into the tank (Read the Darwin Awards for more information on people who did that).

Kevin,
NO problem! Hope Jan's Mom recovers in a timely manner.
