My car has not performed well at WOT since it was restored. It starts missing and performance starts falling off after 4500 rpm, but runs well under normal driving conditions. I eliminated most of the normal culprits and have always suspected a fuel supply issue. Today I was under the car and found a small kink in the steel fuel line where it goes over the axle. Not sure if this happened when I put the body back on the frame of when I installed the line on the frame but I think it is the issue. My question is has anybody replaced this line with the body on the frame? Does anyone make a flexible steel line that could be spliced into the existing line? I would like to find a solution that does not involve raising the body from the frame. Any input would be appreciated.

 

can you post a picture/s of the kinked line? since you're dealing with the fuel system you want a profession repair, no leaks what so ever. before you begin surgery, I would exhaust every other possibility, fuel pressure, carb, electronics. a trip to the chassis dyno may pinpoint the problem. good luck

 

I replaced my complete line from the tank to the motor via pump (electrical in my case) with steelflex lines. Easy to do, no need for taking of / raising the body.

 

Can you just repair the small kinked area?
