I was under my truck tightning the oil pan bolts up a little bit. And stumble across a couple wires that looked kinda not original ya know. Well I start to trace them and come to find out. The previous owner had installed a hpfp fass fuel pump. Wow, I couldn't believe it. It's just the fass pump, not the system. I now know why at idle my fuel pressure is 20psi lol. Well my question is, should I still save for the fass system or will this suffice until I get a few upgrades? How much hp is achievable with this pump? It's still got the 3/8" fuel line. Thanks
