HUMMER H1 Raptor 100 fuel pump kit
A huge upgrade over stock lift pump. The stock LP only makes around 4-6 psi but Stanadyne calls for at least 9psi. Even better if you run it at 13-14 psi.
The engine will run better, injection pump should live longer, you will be supported for other mods like an ECM tune, exhaust, turbo upgrades....etc
Has a lifetime warranty and is Made In USA.
