I have been doing a lot of research today about lift pump alternatives and replacements. The FASS is nice, however I don't want to spend that kind of money. I like the big line relocate kit to the frame rail. I want an affordable solution that will be reliable. I'm looking for something that will support maybe 350HP. The more research I do, the more confused I get. I know that Carter is crap. What about the Holley pumps, or the Raptor. Can' t find any info on the Raptor online. Any help will be greatly appreciated. Thanks.

 

i was recently in the same boat as you. confused about what to buy i went ahead and got a airdog 100gph kit, i just got the kit the other day and it looks like a great kit, its goin in tomorrow. i paid 499. with free shipping band new from dieseldistributors.com best price i could find.

the kit includes everything you need; fittings, pump, very clean wiring harness, and new fuel lines which is also a stock filter bypass, heavy duty mounting hardware and brackets. just an all around good kit.
i will post back tomorrow about how the install goes if you'd like.

oh and fuel lines are same as a bigline kit i believe. about the size of a garden hose!!

 

Please do.

 

ok so i got the kit in. and yes its running with no fuel leaks. . . . yet. running at a steady 17psi alot better then the 7psi i had before!

alright so the kit is well put together kit and i beleive the install was kinda a pain in the rear. for these reasons. (remember i have never touched a diesel before.)
here they are
instuctions are very very horrible.
dosnt say what to do with the factory filter housing.
dosnt say what to do with the factory vp return line or sending unit. (remember i had an intank pump)
i cut all the factory lines so i had to rig up new return lines from vp to tank.
well i think thats about it. i guess its not that bad of a kit just very unclear.

if you decide to get the kit and install it yourself you will most defenitaly need a lift and an extra hand or two. and do not cut factory fuel lines and try your hardest not to break the little plastic clips on the fuel lines. if you can get someone who has some experience with these type of kits.

also i would most defenitaly do the conversion again. and 2nd time around would be alot easier and faster.

i think thats about it. . . .

 

no more than 14psi is what I have always been told.

The carter pump is not junk. Just the Dodge location for that pump is a bad idea.

 

The bigline kit from GDP is 3/8" Airdog is 1/2" lines.I think those carter pumps are junk....take one apart and look at the pump gear..the part where the motor engages the gear is PLASTIC!!!..you have to shine your flash light up inside to see it but yes they are plastic

 

Heh-heh-heh...
My favorite topic. I have been saddened though that too few people truly experiment with this but prefer to buy a kit. Well, I understand - we'd rather get the truck up and running, and have fun with it.
Anyway, options are numerous. Depending on what you want to spend you can get away with less than $200 and over $800 and get high reliability. Let your wallet and your needs be your guide... and let us know what you decide! While sheer number of this or that installation is not really a hint to what's better, reading people's experiences with various systems is very beneficial to all.

The Carter pumps are not really junk - if, when new, you pulled it off the filter and mounted it back at the tank, where a vane-type pump should be, failure numbers would be reduced to normal factory defect and run-time levels.

That nylon coupling prevents any imbalance in the rotor\vanes from damaging the motor\shaft\bearings - it is a good concept - but, the whole 'mount it on the engine' concept was an all around bad idea, based on the 12v diaphragm pump location and mounting scheme - that pump was specifically designed for draw service, pulling fuel up from the tank, as were all the engine mounted-diaphragm pumps since back in the '30's - prior to that the fuel tank was mounted high up in the cowl, between the firewall and the dash, for gravity feed to the carburetor.

What I don't understand is why DCX persisted in that location from '98.5 to '04, with all the lost Carters and VP44's in that interval.

 

What I don't understand is why Cummins did not keep the mechanical LP system on the 24v engine? They could have at least kept the 12v pump lobe.

 

yeah I'm with you the mounting point does take a ton of life from the carter pumps..but they are still junk IMHO...shoot member vzdude burned up 2 BD(carter) pumps in like 2 months!!!(mounted to his frame rail)https://www.dieseltruckresource.com/....php?t=182267I would not trust one on my truck..there are soooo many better options out there why even waste your $$$

 

i bought a holley hp 150. compleatly rebuildable, and resonably priced(i guess?)$200ish iirc. works real good and is quiet for being a gear rotor pump

 

I think Cummins put it there since I understand they use it that way on other applications besides Dodge.

I had a carter by the tank on a gasser back in the early 70's. It didn't last worth a darn either. IMHO, they are still junk.

 

Those were the early design: been there, done that - and, Diesel fuel is a light oil, really good for sliding vane, gear, gerotor, and other mechanical pumps

That location on the filter does have one good benefit, tho: it's easy to replace......and replace........and replace.........and repl......well, you get my drift, right?

 

Jturs,

You are 1,000% correct on the Install Manual being a piece of junk!!!!!!!!!!
I just put in a major printing center (mega bucks) that can do up to 35 full color copies per minute. It also folds, staples, and colates. We will not be sending out any more junk manuals! My appologies to all! This is just one more issue to clear up since buying the company back.
Additionally, the manuals will be posted on our website very soon. They are all going through a major face lift!
