Gas Fumes[240-260/83] posted by Mark Erickson on

My 83 240 (B23F w/Lh 2.0 and AW/71) is starting to have a strong
gasoline odor about it. I smell it in the passenger compartment when
I'm driving. It has been happening once in a while, (I kept thinking it
was the other guy's car that was leaking gas).
The connections at the fuel pump/filter look dry, Does anybody have
any suggestions as to where to look????? The engine doens't seem to
be the source either... Any suggestions on where to look??

Here's a thought: Inspect (but don't tug or bend!) the fuel return line where it goes under the rear seat, up over the differential.
I've had 2 rot out there, and I think it's common on the older 240's. I successfully repaired them with about 6-7' of fuel hose by splicing up as close to the fuel tank as possible and back down around the transmission. On one car, I connected up at the sending unit. You can tie-wrap the fuel hose alongside the supply line.
If this is the problem, be prepared to have gasoline dripping down while you're repairing the line. I would not do this over asphalt. Be sure to have plenty of ventilation, and be very aware of the fire hazard.

Also check the fuel return from the FPR to the metal pipe. This can leak with little evidence left behind due to evaporation. It can also (and does) cause a fire under the hood, just by having proper conditions upon starting. The starter is the fire starter.
Check the copper washers @ the fuel pump ck valve. That's the most common leak I see.
Check the overflow tube that goes through the trunk opposite the spare tire well, and the vent hoses there too.

I had the same repair as Dan. I used a piece of original bundy pipe ( What it is called at the dealer) and connected the new with the old via small sections of fuel line. Bundy pipe did have to be bent to match the original piece. Mine started out as a gas smell then progressed to a small seeping leak. I let the fuel tank run as low as possible then cracked the leak open and drained into a container before I started. Hope this helps.
