i converted mine to nylon all the way to the engine. metal doesnt last long around here. if your dropping the tank you can start at the metal there on the sender, they have adapter bushings and you can get adapters for the filter or just use nylon quick connects and a filter with that on both sides. they have a adapter like the one on the rail so its way easier to run than metal too. just takes a little experiance, after you do a few it ends up being way easier. the carquest here had everything coils of 3/8ths feed and 5/16ths return and all the adapter bushings and rail connections.
