Fuel lines for a 3.2l with Motronic FI conversion, my "how to" from gas tank to engine Options

[jim912928]

I was fortunate enough that the fuel lines on my engine were fine…so I only had to worry about connections from the engine to supply and return lines. However, I didn’t want to use the old plastic lines and I needed larger diameters all the way from the tank. This sounds easy but it did take a lot of finesse. So, I decided that I would go AN from the tank to the engine (as best I could). I do want to identify several suppliers I used: 1) Pegasus for all the fuel lines, metric to AN adapters (engine return and inlet on the fuel filter) and AN fittings, Tangerine for the stainless tunnel lines with AN fittings on the engine side, JEGS for an AN fuel filter, banjo fitting for the 911 fuel pump (actually a honda part) and a brass reducer coupling I used for the return line up front and finally CB Performance for some really cool metric fuel tank (for VW's and 914's) to AN6 adapters.

First the Tank, here are the components I used: VW/914 adapters from CB Performance to AN6, AN6 Barbed adapters for the fuel lines, JEGS AN6 to AN10 fuel filter, AN10 Barbed fitting and the JEGS banjo fitting for the fuel pump to AN6. I retained the fuel tank sock and the little extensions for both the inlet and outlet by cutting off the exposed side. Assembly was pretty straight forward and the fuel pump/fuel filter package actually fits better than the original parts. I drastically reduced the size of the 10M hose by using the 180 degree AN fitting. I used FI hose clamps up front exclusively!
