Engine/Transmission (1998.5 - 2002) Campaign lift pumps are junk too!

[RHulette]

After picking up a couple of the $65. 00 Cummins campaign pumps and Vulcan relocation kit in March, I thought I'd be through with messing around with lift pumps for awhile.

WRONG!

After only 2 months and about 2 thousand miles, my lift pump is making occasional whining noises and pressure has dropped to 9-10 psi.



These "special" campaign pumps are just like the one's they were suppose to replace - JUNK!!!!



I'm going to replace it next chance I get with the 2nd pump. Until that one craps out, I'm going to get a FASS... . I've had enough. .



The only consolation - Now that the relocation kit is in, putting in another pump is a no brainer.

Sorry to hear about your troubles. I can feel your pain!!



Just remember, FASS is a four letter word that means, electric pump.



Maybe a good time to look at the RASP or Mitusa.

What's the problem with 9-10 psi? I was told as long as I have 5psi or more I'm good to go.

 

[JOrtman]

Yeah I don't get it either. Did a fuel pressure test for the pump and getting 6 psi. The Dodge service manual says it should get 5-7 psi.

 

[Gary - K7GLD]

I would imagine his concern isn't as much over the actual PSI the pump is currently supplying, but the funny noises, and the FLUCTUATION of PSI that frequently is a sign of a dying pump...



I'd be concerned too!

 

[ThrottleJockey]

RASP??



I would own a RASP if it did'nt need AN ELECTRICAL FUEL PUMP TO WORK!!!



So..... your'e going to need the FASS anyway... .



Uh, RASP guys? Why didn't ya just reverse engineer the 12 valve mechanical lift pump?

Hey smart guy it DOES NOT need an electical pump to work, just fuel be it electric or manual makes no difference.

 

[ThrottleJockey]

Really??



That's great! But lemme ask you a coupla' questions.



One. What's a manuel fuel pump and where can I buy one...



And two... Isn't that a FASS ON YOUR TRUCK!?

 

[elandon1201]

My spelling is correct my friend so i dont understand your statement. And yes it is a FASS but I hate to see people who dont have their facts straight yelling at people.

 

[ThrottleJockey]

Who's yelling at you for your spelling? What do I look like, your third grade teacher?



I want one of these manuel fuel lift pumps your'e talking about. Fess up! Where do I get one??!!

 

[elandon1201]

Manuel???? Oh you mean Manual. Well you can go to DTT's website and purchase a RASP system which works of the crankshaft MANUALLY. Or talk to F1 diesel and get a cam with the lobe on it which will drive a 12V pump on a 24V engine. See they are MANUAL fuel pumps which means they operate without electrical current, operated by moving parts from either the crankshaft or camshaft using the engines RPM to drive the pump.

Back to the thread I think you are right on putting a FASS 2 in will be a snap. End of problems.

 

[ThrottleJockey]

Hey professor,



That ain't manuel, or excuse me manual.



That's MECHANICAL. You get an 'A' in spelling... .



... however you'll be attending summer school for auto shop.

Manual-Definition: Operated by hand.



This is a M A N U A L fuel pump:http://www.northerntool.com/webapp/wcs/stores/servlet/product2_6970_200129224_200129224

The Rasp uses an electric lift pump to start the engine.

Youre right I misused of the word, but still the point remains an electric fuel pump is not required to supply the VP44. I choose to use an electric pump but it is not required to get fuel to the VP.

Oh yeah it is.



IF, and I mean IF there was a mechanical alternative to ELECTRICAL fuel supply REMOVING the electric fuel lift pump from the equation, don't you think that that would be THE biggest 98. 5 to 2002 24valve VP-44 equipped truck selling accessory?



You couldn't manufacture enough of them!



The Rasp does not replace the electric lift pump. It works in tandem with it. Meaning it could STILL leave your Rasp equipped truck stranded.

 

[Tiger Rag]

The next time I have another problem with an electric fuel pump (I have the BD pusher kit) I am going to get a helix cam and mechanical pump from Don M and fix it for good.

Hmmm, that does exists. I run one. Cam and 12V mechanical pump.



Anyway, who cares. Pick what you want to run and be happy with the decision. After dumping the electric fuel pumps, I can now say that I am happy that I no longer have anything electrical other than the ECP, PCM, batteries, Alternator, APPS, Cam position sensor, IAT, MAP and VP44 to worry about.



What a great feeling!! :-laf

Just installed a new cam with the bolt on gear. Very sweet!

Good thing I've got a fire extiguisher..... :-laf

Alot of good points here, and maybe each are right in different views. I dont have experience to say one way or the other on a modified ISB in a Ram, but I can with no uncertainty say that almost evrey QSB engine (they come in 4 or 6 cyl, and use the VP44) does not use a lift pump of any sort. The engine has to crank long enough to pick up electronic loation sensors (Cam & Crank), that the internal charge pump can build up.

The QSB is an ag/ind. version of the ISB, pretty much picture 24v electronics and pump on a 12v engine.



bottom line guys, a VP44 can sart the engine without help



Remember this happens with minimal fuel line restriction, and the RASP may be enough to stop the process unless an electric pusher is involved to get fuel passed the RASP.



Just a little info to feed on.
