Everything you need to make a gt500 dual fuel pump upgrade except the wire harness. I have for sale the gt500 dual fuel pump, used. Also for sale is the gt500 FPDM. Everything works fine. I replaced the pump thinking that was the problem with my fuel pressure issue. It wasn't. Turns out it was the harness not being snug up against my fuse box. I benched tested the pump just to be sure and it works just fine. The FPDM was also purchased for this reason and I no longer need it. Asking $250 shipped for the pump and $40 shipped for the FPDM.
