Fuel Lines

May 26th, 2010 No comments

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.

Anticipating the higher fuel usage that I’ll be experiencing at the track, I bought a 3/8″ hard line to replace the 5/16″ stock unit. Taking a hint from Carroll Smith, I put heat-shrink tubing on the line in the wheel-well areas, to protect it from rocks and whatnot.

To go from the hard-line to the pump, carb, and fuel cell, I installed Aeroquip AN-6 line and swivel fittings. Making these lines was fun. I found that the best way to cut the stuff was with a chisel and a big hammer! I tried a cut-off wheel, chop saw, hack saw, and found that the cut-off wheel and chop saw left a lot of debris inside the line. The hacksaw got dulled nearly immediately on the stainless braid, and the braid tended to fray too easily. Wrapping it tightly with electrical tape and chopping it with a chisel worked the best.

Aeroquip Vise Jaw InsertsI also bought the Aeroquip vise jaw inserts, which I found to be of great help in the assembly of the fittings. Sometimes it’s worth it to just buy the right tool.

I lucked out and found a guy who had bought a 16 gallon Fuel Safe for his Mustang, and hadn’t installed it. So it was new – still in the box – and at a used price.  The Centroid sending unit that it had installed was not the right ohm range for my gauge (I bought a full set of Stewart Warner Stage III gauges from Ray), so I had to get a new one of those. No problem there though.
