lift pump mod???

[ryecreek]

thinking my 03 pump is smoked

the question is. .

can i adapt the oem lp and pusher (18-22psi) off my 2000 which i totalled without over pressuring the cp3???

still under a 100k but can't be out a truck for a week or a day at that! and the nearest dealer i would let even look at my truck is 140miles away. and i don't want the in tank retro fit anyhow

and i rather not pay for a new one from cummins plus they are 150 miles way

so will it work

hoses and fittings are no problem i have and can build what is needed

heard of holley blues being run too how are the PSI longevity ect?

Take a look at glacierdieselpower.com for a lift pump replacement. He has put together a nice kit to replace the lift pump. One of these days I will get around to ordering one.

What Jeff Said

However, if I had an '03 still under warantee I would let them put the in-tank

pump in.

Why? Because it works and therefor should make a good backup just in case

my Walbro should fail.



Basically that is what I did in a way except I already have the in-tank pump

as my truck is an '05. But I had no real faith in it lasting so I installed the

Walbro for Glasier Diesel Power.



I can, and have, just to check, switched it back to the stock pump to see if

it worked. There is extra pressure drop because of the necessary check valve

but I can drive at interstate speeds and still have 3-4 psi fuel pressure.

Not the greatest situation for towing but at least you could get home or to

some other convenient place to change out the Walbro at you liesure.



Just something to think about.

LSteiner,



You bring up a good point. However, it is my fear of the in tank pump that is making me consider the Walbro pump. I want to be able to change it out on the side of the road if necessary. With the walbro, I can keep my factory LP as a spare and not have to worry about it.



You can argue it both ways, and both are valid arguments. Those are just my thoughts on it.



Either way, I think it comes down to the Walbro being a very good alternative.

thanks but as noted above i'd like to use the vp44 lp and pusher (if needed) since i have enough spares on hand to last a long time and napa stocks them

There is no need to worry about over pressurizing the CP3. However I do not know if the fatory lift pump off of a 24V will bolt right up. Even if it does, you may need an adapter for the filter housing inlet.

 

[ryecreek]

thanks

no worries i have a full stock of fittings one way or another it will work.

i will probably frame mount it along with a pusher.

do ya know if the crd modulates voltage (i read in a search it did not) like the 2nd gen 24v?

thanks again these 3rd gens are new to me

The pump you have will work. Like it was said don't worry about over fueling the CP3 that is what the bypass is for on the CP3. I have done a Blue pump and it has worked so far... I know a couple guys with them also, longevity varies from 1 month to 3 years.



Just give it some fuel..... somehow.

The fittings are not the problem. It is the adapter you will either need to buy or make that allows you to attach the fuel line to the rear of the fuel filter housing.

Glacier sells those also. Not sure what the price is but I'll bet it is easier than making your own.

yeah if figured that out as soon as i took the lp off WTF

after 5. 5 hours on the lathe and mill i got it done

all seems to be fine makes a steady 15psi and enough volume to nearly fill the filter canister from empty on a short pump cycle.

at least the pumps are easly accessed and readly available and much cheaper

I was hoping you knew about it before you got into the project. :-laf Well, that part of the problem is behind you now. Like you said, it will make replacements a lot easier in the future and not too mention finding a pump will be easier since you can make most anything work in a pinch.
