Aftermarket pump by Holley. Same exact one with same pressures a friend of mine has been running on his 02 for three years since I have known him, he has basically exact same truck I have he ran 1/2 " line same pump and same pressure as mine his has been 3 years and never missed a beat. I might see if I can lower the pressure some it has two adjustment screws on the regulator.

Okay all sorry for the late reply I have been in hospital and havent had time to post. Just wanted everybody to know the outcome. Losing prime was the Copper washers bad on fuel inlet and return at VP-44, I replaced these no more losing prime. The loss of power was the MAP sensor (I learned that on a diesel this is same as the boost sensor) New sensor was over $200 at parts store so before replacing I removed the sensor and used an entire can of map sensor cleaner on it (be careful not to damage the little probe in end) cleaned all the carbon buildup from sensor replaced it and it worked beautifully. Removed the factory lift pump from side of engine and replaced with aftermarket pump mounted to frame rail between tank and filter housing, also bought and installed filter and filter housing between tank and new pump (you can never have too much filtration) ran new fuel line from tank to factory filter housing and installed new pressure gauge in cab. New pump runs 40psi at idle and around 25 at WOT. Truck runs like a new one so far no problems. Thanks to everyone for the advice and suggestions.

By fuel manager I assume you mean the filter housing. I do have stock nipple from lift pump to filter housing will check both of those today. Dropped fuel tank yesterday so clean it shined inside there went ahead and repaired fuel level arm while there. I did find an aftermarket diesel transfer pump that runs around 10 psi. I also located an aftermarket fuel filter housing that I had tucked away until a day like today. My plan is to add the filter to the frame rail just past the tank and then place the aftermarket pump between the factory lift pump and the newly added fuel filter and see if pushing the fuel to the lift pump helps. Bought new gauge to monitor the fuel pressure. Can anyone tell me where to hook the copper line in for the in cab gauge?

I dont think the filter canister is going completely empty maybe I misspoke I mean it is not full as it should be and the return line from head is a good place to start looking. I am replacing the fuel lines with marine grade rubber hose from the tank forward today just to be sure I don't have an air leak there so I will see if there is a problem there. Does anyone know if there is a good replacement or perhaps a supplement pump I can add on that will help get fuel to the lift pump perhaps then it might last longer or maybe even bypass the factory lift pump all together? A FASS system is out of the question on my bidget.

Headed to parts store to get a fuel pressure gauge now. If fuel pressure is low what could cause that as I said the lift pump is new but I don't think this was one of Dodge best designs for lift pump. Would love to put FASS system on but budget constraints make that impossible. Is there an alternative solution that is more economical than a FASS fuel system? Thanks for the advice I will have fuel pressure gauge Installed shortly.

I have an 02 2500 6 SPD manual tranny. Bone stock except cold air intake. Recently truck seems to be losing fuel prime and I can find nowhere it is going. Truck sits overnight and fuel filter housing will be empty causing very hard start problems. When I do get it started seems to idle fine. When I drive it sounds like turbo is not coming in until upper rpm range. Truck will barely pull itself up even the smallest of hills. Lift pump is new (one mounted on engine) and seems to be working fine fills filter housing in under 10 seconds. No DTC codes. Any ideas or suggestions would be greatly appreciated.
