[TR] help needed with persistent gas smell

[wbeech]

Have had several TR3s and always noticed the gas smell if left overnight in
a small garage.  I have just attributed it to the open over flow pipe.  Have
never had a gas leak per se, sometimes there might be just a little dampness
noticed around the bottom of the SUs, not enough to drip.

Thanks Randall and Dave, I appreciate your responses.  From my brother's
description, this way more than the faint smell of gas and I think it is
abnormal. I have 2 triumphs in my garage and my wife with the nose of a
bloodhound doesn't notice any gas smell. There are no wet spots and no
dampness to be found, so I don't think a dye in the gas will reveal anything
and the smell is strongest in the trunk so the fuel pump is unlikely.

 

Still, your point about the close system makes me wonder if there is a way
to add a carbon canister, maybe to the overflow pipe, and then close off the
vent in the fuel filler cap.

 

Thanks,

Bob

Dave has an excellent point. My 1959 TR3A resides in a heated garage and
when first entering, the scent of fuel is faintly noticeable until the
overhead door is opened.

Welcome to life in the 1950's.  There is a reason houses of that era had
detached garages. From the 1970's on the EPA mandated and evaporative loss
controls and charcoal canisters was born.  But the TR3 had none of that and
the gas tank was vented directly to atmosphere.  You will never get it to
the level of a modern car (such as TR6) and there will always be some aroma
of gasoline in the garage.

My brother is really enjoying the TR3A he bought several months ago, except
for the smell of gas in his garage every morning. The car was recently
restored but he had all the fuel lines and carburetors checked by a British
car mechanic shop. He had the overflow blocked to no avail, I convinced him
to replace the gas tank suspecting pin hole leaks at the bottom and that
didn't help either. The smell is strongest inside the trunk so I suggested
that he blow up a balloon inside the filler and see what happens. No smell
so he had the hose from the filler to the tank replaced, but the smell
returned. Next he covered the filler with a plastic bag, The smell went away
but if he took it for a short drive with the bag in place, the smell
returned after he parked the car in the garage.

 

Other than replacing the filler cap, I am out of ideas. We considered
plugging up the vent hole in the filler cap, but he won't be able to drive
very far like that. Has anybody struggled with this issue and found a
solution? Anyone have any ideas on what might be going on here?

 

Thanks for any help,

Bob
