So I had the Sai Li fuel system (with the GT500 pumps) installed on my car last year so I could run E85 and was wondering if I should run an aftermarket fuel filter. I know the stock GT fuel filter is built into the tank but I'm not sure if it is part of the stock fuel pump assembly that was removed or if it is located somewhere else in the tank. So I guess I'm wondering if I have any fuel filter at all now that I switched to the Sai Li fuel pump module, which is a modified 13-14 GT500 fuel pump. The GT500 has an external fuel filter, the same one that the 05-10 mustangs use, and is part of the fuel line. I was planning on adding a fuel filter that is E85 compatible. Anyone have any recommendations on what brand to run? Also anyone know what size the stock feed line is on our cars so I know what size fittings to buy? Thanks in advance
