Posted May 20, 201411 yr What pressure should I see on the inlet of the VP44 Fuel pump? Also I just replaced my fuel module in the tank and noticed there's a push pump on the module? So u s there 2 pumps before the filter housing?
May 20, 201411 yr Welcome to the forum! First off, I think you might want the 24valve forum. The 3rd gen dodge cummins trucks dont have a VP44, but rather a CP3 injection pump. They are common rail (CR) injected engines vs the old mechanical style individual cylinder injection like the VP44 and P-pumped 1st gen cummins motors.
May 20, 201411 yr Wasn't there a cross over year where they had 3rd gen body and still 24 valve engine? Like 2002 or 3? Critical to know common rail or not. If it's a VP 44, 20 psi at idle. One good pump should be enough. I'm going to go with a Bean Diesel sump and ditch the in tank suction draw all together. Sounds like someone added a new pump without removing the tank pump. Seems like 2 pumps is too complicated. Edited May 20, 201411 yr by joecool911
May 20, 201411 yr The 2002 was all VP44 and in 03 there were all CR trucks. If you have a VP it's a 2nd Gen.
