i have been having some problems in the past with my ip acting stupid. when you runn the outta it, it starts missing for a couple seconds then runs fine then missing again an wont idle, any help would be great truck has great fuel pressure, no plate. with 191'dv's and 4k springs

 

I had the same problem with mine, turned out to be a loose fitting. check your fitting on the inlet side and return side of the pump to make sure you have no air leaks.

 

well i have already changed the pump out with another 1.

 

make any difference?

 

yea truck runs fine, but doesn't fuel like the other pump, all my stuff from my other pump is in this one. power just aint there!

 

what pump did you swap in?

 

175 same as old 1

 

 

Return line plugged up?
