Quick question on installing a fuel pressure guage for the lift pump. I've got an electric gauge, sender, banjo bolt, and two washers. I know how to install them, but want to know the start-up or bleed procedure.

Is just turning the key on and off a few times to run the lift pump without starting the engine enough, or is there a better bleed procedure?

Turn the keyswitch just barely enough to engage the starter then quickly release. This is known as "bumping the starter" and will get you a free 25 second lift pump run. I "bump" mine 3 times after changing the fuel filter or any other fuel work.

I have always had to break the injector lines right at the head to get the air out and then tighten them as it starts ti squirt out. usually only the first, third and fourth cylinders.

Will the lift pump pressurize the lines to the injectors at all, or only the injection pump?

It will pressure to the injector pump only. You need to break the lines and watch while someone cranks the engine. While cranking watch for diesel to squirt out as soon as it does tigthen up that cylinder and move on to the next one. as i mentioned before you should only have to open up three lines. make sure you loosen the nuts on the head side not the pump side. good luck.

What are the solutions for a very unobtrusive, finished looking single gauge mount? Dirt cheap if possible.

This is the kind of mount I was thinking about. Is there any accessory that might be in this place?

My friend has an '01 with symptoms that match a bad lift pump. Very hard to start after changing fuel filter and sometimes surges at highway speeds. Does running with a bad lift pump usually harm the fuel distributer/injector pump? Thanks for any info. Allen- e/m me if you can

From what I've heard when your lift pump pressure drops low enough it will kill the injection pump($1500-2000) within a few miles, as would a dead lift pump.

Fuel lift pump

Changed the lift pump in the 2001 Cummins and it runs like a stripped.... you know. Seems like there is no damage to other components. Thanks to all for the information. By the way, the lift pump was $200 at NAPA through my workplace. Amost 300 otherwise. Allen

I have an idiot light system, activates below 5psi. Bright led that I installed in the istrument cluster. Gets your attention NOW when it activates. cheap insurance at $50.00.
I also used the cubby storage for a pyrometer. looks good and is not in the way. I find the pillar mounts to close in my face

Lift pump idiot light...

Where did you find the light kit for fifty bucks? Everything I have found is at least fifty percent more. Thanks.

DerHerr, that's where the seat heater controls are in my truck. That cubby is a great place for a fuel pressure gauge.

Did somebody say cheap? Meet the cheapo lift pump fuel gauge...free.
It's a US Gage rear connect, wire tied to the trailer brake bracket and found to be within 1/2 psi when tested. :cool:
