  1. 3rd Gen. Powertrain
    I noticed today coming home my truck would occasionally jump in rpms only like one tick on the tach but you could feel it. No cruise, and would do it in any gear and speed about every 30 seconds. First thing I am doing is draining the housing of the filter, going to replace the filter then go...
  2. 2013-2018 Powertrain
    Hello, I'm hoping that someone can help me figure out what's going on with my truck. I recently replaced the power steering pump and after doing so I now have a lope at idle. I don't believe there is a connection with the pump but I may be wrong as I did move the airbox and I could have caused...
  3. 2010-2012 Powertrain
    Not sure where to start so - I have 30% over injectors, less than 50k miles old from Exergy (truck 280k) tuned with a RaceMe Ultra on +60hp tow tune. During the summer months, if I ever did a hard pull I would get a CEL with code: P0087: Fuel Rail Pressure Too Low. Back then I would think...

    Just bought an 01. The owner had just installed a new in tank fuel pump/lift pump a month before I bought it. I just installed a fuel pressure gauge to monitor lift pump pressure. I discovered the lift pump was not working after installing the gauge. I have 12v to the harness on the tank when...

Got the pump plugged in, positive and ground hooked up, and went to clip the last piece together... aka the...

  14. Glacier Diesel Power
    Like many things in life during 2020, we had pump sourcing issues with our Fuel Boss pumps. The supplier consolidated and the pump was discontinued. However, in November 2020 we found a comparable pump. We spent hours testing the new pump on a 1998.5, 2nd gen and on a 2007, 3rd gen. Both tests...
  15. 98.5-02 Non-Powertrain
    I recently changed my starter and since then my truck will randomly cut out when I try to go above 1500 RPM. If I shift before 1500 RPM then it doesn't happen, but I live in SoCal so I can't really drive at highway speeds like this. I don't know of the lift pump is going out or if it's a bigger...

    I’ve been trying to figure out what the factory lift pump pressure should be my truck runs about 9psi when idling if I get on it it will drop to 4 or 5 psi. What is the lowest the pressure should ever be?
  17. 98.5-02 Non-Powertrain
    I'm already going to buy a FASS for my truck, but I had a couple questions and also need some pointers in the right direction. How should I determine which pump to get, and does it at all bypass the VP44? Or does it go through the VP44 after bypassing the factory pump? If I can avoid having to...
  18. 3rd Gen. Non-Powertrain
    I own a 2004 Cummins that I've put a ton of miles on over the years. 413K to be exact. It is basically bone stock as far as the motor goes. It does have an edge tuner and S&B intake. As of lately I've had a lot of dead petal. Could this be a lift pump issue? Major power loss and if I turn up the...

    Hey guys sorry to put up another one but couldn’t find exactly what I was looking for unfortunately and it’s been awhile since I’ve been in the 24v game.

    What up fellas I got a 99 24v recently and the guy before me has this Oasis lift Pump on it. I’m looking to change the filters on it but I can’t find any information on the company/pump anywhere.
