Injector Pump and Lift Pump are toast. Now What?

Hey Gang,

I have a 2001 2500 with the 24v 5.9. It wouldn't start on me the other day and the shop is telling me that the lift pump is bad (currently pushing 8 psi) and the injector pump is also toast. I have 112,000 miles on the truck.

I'm considering either the FASS direct replacement pump, or the full FASS 95/95 system. What will the full system get me that the direct pump won't, besides water and air filtration? Is it really worth it?

What about the injector pump? Do I do a factory replacement, get a Bosch VP44, or a high performance VP44?

This is my daily driver and I do quite a bit of trailer towing.

Also, I've always been mechanical and have worked on lots of my cars. Are these easy to do myself?

Any feedback or information would be appreciated.

Thanks!

Jake

I'd reccomend a Standard Output VP44...I got mine from Industrail Injection and I love it, however I have also heard a lot of good out of the BlueChip VP44s...

As for a Lift Pump, that FASS Direct Pump inst any better as it is still up too far from the tank, I dont have any hands on experience with it but what I can gather it isnt much better then stock, and Its pre set to like 16 psi, so with that and its location it wouldnt take anything to drag it down. I personally have a Pure FlowTechnologies Raptor 150 pump, which mounts on the rail and doesnt have filters, you can also adjust the FP to whatever you wish on the side of the pump. Nothing against FASS, its your truck, but for the best money a Raptor or an Air Dog (with filters) is the way I'd go...

I agree with Nate. The airdogs have better price and work just as well. I would go with the filters myself. Once you get that done you can add some power too...

Your below low limit in fuel pressure! Remember the only thing lubricating the VP44 is the fuel so if you short the pump for fuel pressure you reducing the lubricant and life!

I'm more of AirDog fan. There small in size fit up under the body better and are much quietier... Plus they have a full tech support!

Stock SO pump is best for ya...

Yeap... From what I heard its a snap... Here is my write up on it...

I would say get an SO VP44 & a good lift pump kit like a FASS or AirDog. I would get the one with the filters & fuel air seporator. But thats just me.

Thanks for all of the input guys. I've decided that I'm going to fix it myself. I feel better now. I'm going to call today and have it towed back to my place... maybe.

I'm going to go with a new VP44... possibly from Blue Chip and the AirDog FP100 with low pressure light. How many of you guys run low pressure lights versus fuel pressure gauges?

Another question: It starts up after it's been sitting a while. I'm thinking that the computer chip on the VP44 is heating up and preventing it from not starting. I'm thinking that I may try to drive it home instead of dropping another $150 for towing. It seems to keep running fine until I shut it off. Should I try it?

GET A GAUGE! Low pressure lights trip much to low. Most low pressure light come on at 3-5 PSI which is too low. VP44 require 10 PSI or more to survive!

Another question: It starts up after it's been sitting a while. I'm thinking that the computer chip on the VP44 is heating up and preventing it from not starting.

Hard start hot is a sign the diaphram has ripped in the VP44 and the fuel pressure is too high during engine cranking. So if you replacing the VP44 the problem will vanish with the old VP44...
