Check your fuel lines!

[Ntenna]

Avanti production began almost 60 years ago. Since then cars have received total restoration, been totaled and everything in-between.

If you haven't checked your fuel lines recently, look at these photos. This is not only the main tank feed over the axle, but the return and vent hoses behind the rear seat. They pretty much tell the story. Getting that vent line upper U-turn out and replaced is really fun. And this is a good running, show-level R-2. A failed pump diaphragm started me replacing everything.

Good catch, my R1 is about to undergo a fuel system upgrade and all new ethanol compatible hoses are on the docket for this very reason.

Good advice, I just replaced all of mine in that neighborhood last fall. I was installing an electric booster pump and the old ones did not look well.

I ran a wire inside the vent hose in the 1/4 and used it to fish the new line back through the high loop in the 1/4 panel.

Sounds good, Brad. Planning on the same.

When I cut the vertical run and pulled the horizontal vent line out, I found the copper pipe was cut too long at the factory, and the flex line going up into the 1/4 panel was crimped shut against the copper pipe. Been folded over since new. Plus now cracked at the top of the U and tank coupler.

If anyone has issues with the tank spitting back while fueling, there's the problem. This one did, and it will hopefully now do it less or not at all. Pictures coming.

I would get a smell of gas in the car every time I filled up the tank.

Found that the fittings were not soldered all the way around. The tank fill tube at the base was leaking and the vent fittings were leaking.

These were not cracked, just poor soldering. Took it to my radiator shop and had it repaired.

If you can get to the tank I would test it for bad joints.

Good luck,

Jim Wood

Really makes you feel good to find (and correct) something like that!
