fuel pump
I have an 01 ram with the fuel pump in the tank. My fuel pressure is around 10 to 11 at idle and 5 to 6 at WOT, i have been told this is not good and i need a new pump. I am not sure what kind to look for and how hard they are to hook up. The truck is almost stock except for the banks exhaust. Any info would be nice thanks.
Can i still drive the truck how it is now? |
Your 10-11 at idle isn't to bad (I like to see at least 15) but the 5-6 at wot is low. I would look at getting a airdog or fass system. Neither are to difficult to install. I'm sure some of our sponsors here would be willing to give you some price quotes and answer any questions you may have on the install:U:

would i have to take out the pump in the tank?

Airdog or Fass would be your best choice. They both include the draw tube to replace your intake pump.

you have to remove the tank to do a install with an in tank pump.

When I bought my '01 it came with a pump in the tank. It was weak, and fuel presure would drop to 0 :booo: at WOT!! I quickly remedied this by installing a second fuel pump on the block where the factory pump would go. These two pumps are now working together in series, and produce 29Psi at idle, and still make 17Psi with my chip set to level 5, and my foot all the way to the floor. I made a "Y" harness to share power form the ECU to each fuel pump. Works very well, and is A LOT cheaper than a FASS or AirDog. I do have plans to upgrade to a FASS, as I do not believe these pumps will keep up to the fueling requirements of future upgrades.

Umm, 29PSI on a VP is too much. You can blow the seals out of the VP if you spike. Imagine barking the turbo, all that air pressure slams the compressor wheel forcing it to stop. Now imagine going from full throttle and fuel flow to almost nothing. Fuel stops just as hard. I can watch my gauge go from 13.5 psi at idle to 12 at WOT to over 15 when I let off. Obviously its not a good idea to run too much pressure.
Anybody seen these yet? Wonder how they'd do for a diesel. Holley Electric ''HP'' Fuel Pumps - JEGS |
