I am replacing the fuel pump on my 98 Dodge Ram 2500 Gas truck. The replacement fuel pump (Napa) has a "rollover valve" that my original did not have. What should I do with this? Do I cap it off or is it the wrong fuel pump?

 

I thought yours would have had it. Maybe the pumps changed? My 95 has a rollover valve. If the one in your truck now doesn't have it, I'm guessing they gave you the wrong part.

 

I had the same problem with my 98. Try looking at a pump for a 99.

 

I did look at the 1999 fuel pump and it calls for the same one as the 1998. Any other suggestions will be apprecxiated

 

I have 98 Ram 2500 V10 4x4. I stepped of it yesterday with it running to check the lights on my trailer. I heard a new noise, yay.
It sounded like a steady alarm, or more like the old tone your phone issued when you were disconnected during a call.
I climbed in truck and was going to run it through the gears and just test and see what it might be. When I stepped on the brakes, the noise stopped.
release brakes= noise, brakes= no noise.
E brake had no effect.

I called some people who know more than I do and no one had any idea except fuel pump (which should not be affected by brakes) and "Crawl under, listen, and find the problem. (Duh.)

So, I crawled under and the sound is coming from fuel tank.

I'm going to order and replace the fuel pump since from what I've seen it either works or doesn't, no sputtering warning. The truck has some miles on it and a new fuel pump won't hurt it none. I can keep the old one for a spare later on in life.

My question is, why the H#*% does Dodge tie everything to the ABS? (My Torque converter is linked into brakes, too.) And why would stepping on brakes have any affect on the fuel system?
