Fuel Pump Questions
 

I have the bullydog fuel pump installed on my truck and would idle around 23psi and about 14psi WOT , I was getting on the freeway yesterday and lost fuel for about 2 seconds. My fuel pressure now idles at about 18 psi and at WOT drops to 0 psi. I can hear my aux. pump pumping before I start it, is my stocker shot? How can I test it?

Sound like your stock LP is dead, change it out and do the filter while in there.

Is the pump in the tank on a 98.5 or up by the engine?

Unless you let the dealer change your pump it should be on the engine right behind the fuel filter. If the dealer retrofitted it then your pump might be in the tank.
here is a good site and a pic of your engine.

I just changed my lp and my psi is 10 idle 8 wot. i put the cummins pump on it. Not the in tank junk.is this right? psi

Sounds about right for the stock LP by itself. I'm sure if it should be more someone will chime in. I have the Bully Dog fuel management system with the stock LP still running and i get 23idle and 15wot.

it used to idle at 15 12 wot.i just read about people having the screen in the fuel tank pluged and to blow air back into the tank to clear it out. what do you think ?

iam going to go try it and see what happends,let you know findings

well that didnt make any changes" but i tapped on the elect fuel presser sender and presser went up tp 13 at idle.shut it off, start it up back to 8 lb tap on it again back up to 13,think my sender is bad?

Get a mechanical FP gauge. It sounds like the sender is at least part of your problem. A stock pump should be idling around 14-15psi. Time to upgrade your fuel system, so you won't be posting similar posts in the not-too-distant future. :)

would like to caant drop the $$$$$$$ right now

A nice AFS Big Dog System for Christmas would put a smile on any Cummins owner's face!
