Cummins ISB fuel pressure gauge install to monitor VP44.
My 1999 Holiday rambler endeavor has given me a few problems starting over the last few months. Since it did not come with a fuel pressure gauge and has the dreaded VP44 pump, I decided to install a gauge so I can watch it when I drive.
It took me about a day of labor to put it in. It wasn't hard, just time consuming running 3 wires from the lift pump(fuel pump) to the driver's area. I had to take the dash all apart to find constant hot, switched hot, ground and headlight for the dimmer light on the gauge.
I bought everything from glowshiftdirect.com
They are a great company with excellent service and products. The gauge, pod, wiring, fittings and every single part I needed were purchased from them. The total was around $130 for parts.
I'm happy to report that with the engine idling, I am getting about 11psi. Under WOT I am getting about 8psi. I called cummins to confirm these being acceptable and they are completely normal numbers.
I have the cummins ISB 53 block, 5.9 275hp. This fuel pressure gauge is in my eyes, very important. Just wanted to give a heads up to any owners that have this engine about the gauge install.
