Fuel smell in interior, cabin, booth, etc.

Fuel smell in interior, cabin, booth, etc.

Written by BillWilliams Sunday, 08 March 2009

Things to check:

1. BMW intentionally put it there. (most 2002s have some of that smell, some more than others)

2. A good way to keep the girl/woman out of the car. Nice long drives alone are good things unless you have the Carl's Jr girl

3. Fuel tank leaking, generally around the seam.

4. Fuel filler boot cracked and letting fumes out.

5. Fuel line(s) under or in the car leaking.

6. Something in the engine bay (hoses, lines, filter, fittings, carb, injection) letting fumes or raw fuel out.

7. Vapor canister or return line not hooked up or leaking.

8. Gaskets around the fuel sender or fuel pick-up rotten and leaking fumes. (This is the most likely)

O ring for sender is 16 11 1 744 369

Twist in gasket 16 12 1 105 332

Bolt in gasket 16 12 1 110 598

9. Fuel lines from tank to rigid lines cracked deteriorated and leaking fuel or fumes

10. You spilled fuel on your boots at the last fill up.

Here's a weird #11: make sure your gas tank matches your car.

 

I replaced the fuel filler neck on my '70 because the old one was pretty hard.  Didn't take the new one long to do the same, but that isn't the problem.  I had "the smell" and decided to put a homemade charcoal canister inline on the vent hose.  Seemed to make it better, but didn't fix it.  10 years went by and I occasionally had more fumes than normal after I filled the tank.  Purely by accident, I had the trunk open as I was filling the tank (in Oregon, normally you can't do this yourself since it's "unsafe") and noticed gas leaking from around the flange that connects the fuel filler neck to the inlet. I did a little sleuthing through my parts book and noticed that the fuel filler neck was different on the '70 than the later Roundies.  The '70 was designed to fit a vertical flange on the gas tank and then clamp to a horizontal flange on the rear quarter panel.  I had the right gas tank, but no flange on the quarter panel and instead the fittings used on later model Roundies, which were designed for the later model fuel filler neck.  As it turns out, my rear end is not original, which I knew because of the long eared bumpers, but I never knew about the differences in the fuel filler neck and related fittings.So instead of replacing my rear end to get the right flange for the fuel filler neck or replacing the tank to allow the correct filler neck, I made a gasket to take up the gap in the upper part of the filler neck where it clamps to the fittings form the later Roundies.  This fixed the leak and should cure at least a lot of the smell since I won't have gas sloshing around in the trunk after every fill.
