JeepcoMJ Posted May 20, 2008 Share Posted May 20, 2008 possible fuel pump failure on the new MJ i've got. no $$$ i have two HO fuel pumps from xj's and 3 comanche sending units, all from 2.5's i'm going to swap the pumps to the rails, put one in this truck, and eliminate the inline pump on the 3800 to replace with an in-tank one (quieter running) anyways, does anyone know if it's gonna work easily or not?

pingpong Posted May 20, 2008 Share Posted May 20, 2008 I remember when I was doing my truggy project on pong and running an inline fuel pump... that there were 2 fuel pressure for the fuel pumps... don't rmemeber what the yr break was... Call a napa and ask them.. they should be able to tell you what the working pressure is for your motor, and the pumps you have Link to comment Share on other sites More sharing options...
