## Description

Fass Fuel Systems DRP 04 2003 2004 Replacement Fuel Pump for Dodge

Review: Doesn't produce under load - I just installed one of these and I'm not happy with the results. This pump will give you 14 psi at idle or coasting but when you need to stomp the go peddle you'll see your fuel pressure fall below 4 psi. and stay there until you let off. Any one with a second generation Dodge Cummins knows that the VP44 injector pump needs mucho fuel to keep cool. This one isn't dooin it when it's really needed.
Review: great product - great product. works as described. seems to make the truck run smoother and more get up and go. better response than the factory part
