I am on a trip and my fuel pressure just went to nothing, so i think my lift pump has died. Unfortunatly i just bought this truck and don't know if it has an it in tank pump or not. Where would it be located if its not in tank. Does anyone know of a way to temporarly fix it to get it home. ie an inline pump cut in. I have some tools with me so i should be able to get it fixed if i can find the parts. I know i can't do anything today, but would like to get started tomorrow. I am in breckeridge, CO until sunday, when i'd like to go home. Any help or sugestions would be appreciated.

 

The VP44 injection pump on your truck should be fed by a lift pump mounted on your fuel filter housing, which is fairly simple to replace - lots of guys carry a spare around in their toolbox... I don't think you'd have an in-tank LP unless Dodge has replaced the LP in your truck in the last year.

Are you sure the FP gauge is OK?

 

I have a new 2nd gen Cummins lift pump I need to get rid off.

 

Napa has the replacement pump,its a couple hundred,that would get you home..that is if your guage didn't come unplugged,or something.

 

$200 sounds high for a lift pump...

 

Yep,thats what I thought too...but thats the going rate here in hillbilly heck.
I've found new ones online for $150 or so,but didn't think he'd wanna wait that long...

 

My lift pump and injector pump both died while driving. I had to buy a new injector pump and went with a FASS 95/150gph fuel pump so far the new fuel pump works great but cost around $650 with all parts to install. Planing on adding an Edge Juice w/ Attitude Moniter soon.

 

Go to a parts house and see if you come up with something like a Holly Blue electric pump. If the guys are worth a flip, they'll help assemble the parts to get you going.

If there is a Cummins dealer open tomorrow, they should have one for way less the $200. Ask for the "Campaign Pump".

Ths is where you can find where the lift pump is located. It's not very hard to change.

Good luck,

 

... and don't forget to pack a spare in your toolbox when you can afford to spring for it!

 

OK, is the truck still running? If so look at the vp banjo bolt and see if that's where your gauge line is. most of us put a needle value right there , and shut it way down (all most off). open it up and see if it just vibrated closed, then bump the starter and listen for the lift pump. if still no pressure see what kind of pump you can find. push come to shove you can cut the steel line on the frame under the cab, and put a holley blue ,or what ever you can find, and it will push fuel through the stocker. You can wire it to a wire that's hot with the key on. you can look at the engine diagram in my sign to find the lp and lp

 

Thanks for all the info guys. The lp is on the engine. My gauge is working because i have about 3-4psi at idle and as soon as i touch the throttle it goes to zero. There is a napa and a carquest near here i think i will call them tomorrow. Are there any special tools required for the changing of the pump, or any other valuble information i could use. I am pretty mechanical, but have never done this before. Thanks again

 

Just wrenches, sockets. Don't loose the sealing washers! They are very hard to come by unless you are at a Cummins store.

Take the filter housing completely out, makes the job easier. Unless you are 7'4" tall you are gonna need something to stand on about 18" tall.

After the install, "tap" the starter with the key, but don't start the motor. Let the LP run for 20 seconds and stop. Do it again 4-5 times to flush the air out. Don't worry that the FP gage is acting funny. It will take a week or so to get the air out by itself. Don't worry about bleeding the gage line or you will be smelling diesel all the way home.

DO NOT OVER TIGHTEN BANGO BOLTS! THEY BREAK EASY! Tighten only to stop leaks.

 

get yourself a hundred dollar holley blue pump, a cheap line cutter and some wire, a couple wenches and you are in business. When I put mine in it took maybe 45 in start to finish. Bolted to frame rail, wut metal lines, attached 3/8"rubber a couple clamps and ran the wire to one of those fuse panel add a wire thinamajigs ($3) and was in business, and no longer have to worry about my injection pump to boot!
