So, I'm guessing the smaller electric pumps that are about $50 would never supply enough volume or pressure for our trucks right? They would just be an obstruction. Well, I have a very worn cp3, I am replacing it with a good unit this summer. The pump i am replacing it with seems very strong, it held rail pressure at 3300us, mine wont hold at 1450. Anyway, i am thinking about getting a lift pump to make it easy on my new cp3. Do any of you think that a lift pump would help my current situation with rail pressure? And if some of those other pumps are good enough for drag cars, what about us? just thinking. Thanks guys.:drink
