Have had it replaced on my Dak b4. The sending unit, pump and filter are all one unit inside the fuel tank.

Just got my truck and it almost does the same thing. Sometimes after braking or coming to a complete stop the truck will drop its rpms below 500 and then kick itself back up before it dies. Never stalled, and this "bounce" only happens every once in a while. Also it only drops one or two times before returning to a normal idle. Do you think I am going to have a problem as severe as his? Could I just be in the preliminary stages of his more serious issue? Whatever the case may be, I'm very interested to see what comes of this.

Seeing as there is no check engine light, I'd guess Fuel Pump/Fuel Filter... which is all one unit, and is located in the top of the fuel tank ... Auto Zone price is somewhere close to $300 for the unit, if I remember right.

How many miles on your truck? [sm=smiley25.gif]

There was about 69,000 when I had mine replaced. I have about 74000 on it now.

ive got 71k on mine. i will most likely replace fuel pump assy cause i know now its not map sensor, iacv, or tps. could still be check valve but i doubt it, so thanks alot for the help gentlemen.

Dont know if you have 15 gal or 22 gal tank, but here is some fuel pumps under $300.00. Fuel Pumps

here are some on eBay for a lot less than $300. Dakota Fuel Pumps eBay

wow thanks a lot but how do i know which to get? there are two different ones for my year and engine- chassis? i may be able to tell if i can get a closer look at the top of my pump? i have 22gal and i think its on top of fuel tank.
