Fuel Lines

I re-did all my fuel lines. Earlier, I described that I’d used the hard line, and then mated -6 fittings and braided line to it. Turns out I need -8 to fully supply this motor, so I re-did them all. Finding a route that stayed away from heat, was well protected, and wasn’t inside the car, was a challenge, but I think I did pretty well with it. In 2 areas, I passed the line through sheetmetal. Ordinarily, you’d do that with a bulkhead fitting. These areas would be pretty hard to reach though (if not impossible) with the car together, so tightening the fittings to solve a leak or something would be really hard. I ended up putting a rubber grommet in the sheet metal, and putting heat-shrink tubing on the fuel line. If I hadn’t put the heat-shrink on there, the line would have ended up cutting trough the rubber in time, and then cutting into the sheet metal. It might also be weakened itself, by the sheet metal rubbing on it. Combining that with mounting the line securely so that it won’t move around, makes for a pretty solid setup.

securing the line so it does not move around is key in keeping it lasting long.
