Mar 29, 2009 4.0 Fuel lines Category: Fuel System
I clamped the fuel pump to its mounting bracket today, then began tackling the fuel lines. OK, an admission: Last fall I measured for, and ordered, a nice set of Bonaco teflon-covered flexible lines for both the fuel and brake lines, thinking they would save me some time and effort. I thought I'd just be able to screw them right on, clamp them down, and move along. Unfortunately, the larger "Dash-6" lines for the fuel system are a lot stiffer and less flexible than I'd counted on. The 90- and 45-degree fititngs I so carefully planned and ordered are totally inflexible, too, of course. There's no slop if you need another 5 degrees of bend within about 4 or 5 inches of the end fittings. This means the lines are nearly impossible to use in the locations I had planned. Today, I ditched almost all of them in favor of old-fashioned aluminum lines. This will give me a LOT more leeway with the bends and tricky angles in areas like the tight bend below the fuel filter, and underneath the fuel selector valve.

The first line I made was the one between the fuel filter outlet and the fuel pump inlet. I only had to make five of them before getting one that was perfect. Argh. Glad I ordered all the extra 3/8" tubing last month...
