fuel hoses in front trunk

[SiberianDVM]

I have a 84 Carrera Targa. I'm pretty sure all of the fuel hoses are original and need replacing. The only time I smell gasoline is when the tank is FULL and I take some corners.

Are the fuel hoses in the front trunk best replaced with OEM parts or will bulk fuel hose work?

Bulk fuel hose is OK for the short fuel pump to tank hose.

The tank vent hoses (small hoses visible in the frunk) are OK to use as bulk but they are metric so easiest to buy by the foot from Pelican.

The filler tube flex hose near the brake master cylinder needs to be OEM.

The fuel lines from the tank (return) and the fuel pump (pressure) that go from the front, thru the tunnel to the rear of the car are OEM (of course).

Probably a good time to remove the tank filter and clean out the fuel tank as well.

If you are just going for gas smell the most likely source are the vent hoses in the frunk

Thanks!

I'll start with the easy ones.

Is there a written procedure for removing the tank filter and cleaning the fuel tank?

I'd check for a leak in the tank first....try the seam on the left front closest to the battery...the coating will hide/mask the fuel leak, but if you're smelling gas all you need is a couple of drops under the bonnet...not to mention the "boom" factor...

look for wetness in the vent hoses (ones in the top of the tank inside the trunk). If none, then try changing the fuel sender gasket.

I had fuel smell on new-to-me 82SC. Turned out PO had epoxied broken fuel expansion chamber, and it leaked. Replaced that, did not clear smell, found all three hoses to expansion chamber had small longitudinal splits, replaced the old black hoses with translucent, yellow fuel resistant hoses from McMaster. They will show future splits. Smell gone.

Thanks, guys. I looked at all of the front truck hoses last night. The "big one" between the filler neck and the tank is smooth rubber, all the others are braided. The filler neck/tank hose looks great so I just tightened the clamps. The other braided hoses look OK but feel soft so I will probably try to replace them.

Do you have to remove the fuse panel in order to replace the small hose that comes out of the bottom of the white expansion chamber and runs through the fender to the black expansion chamber?

Sooner or later, I will probably swap this whole thing out for a fuel cell.

As noted above, check that short hose between the fuel tank and fuel pump under the car. Mine was covered in braided cloth, and always appeared dry when I looked at it, but I found that it was wet to the touch. Replacing that fixed the ever-present fuel smell in my garage. The old one was in an advanced state of decay, and if that line goes bad, your tank will drain itself all over your garage floor.
