Oh I hear you Mayfair. It was a simple fix. But at the time I had just dropped $1800 into rebuilding the tranny so things were a little lean. I'm definitely going to upgrade in the future though, anda FASS looks like the answer. I guess you can call it an insurance policy on your injector pump.

 

That's the way I looked at it.
I didn't really have the 700 bucks for the FASS, but I definately didn't have the 2K for a VP-44 !!

 

That kit uses a walbro pump which are excellent pumps. I used one for my car. If I'm unhappy with the quality of the fuel line I'll just bend my own steel lines. Sure, it's a kit that somebody took the time to piece together and make it work, and from what I've read, it does just that. Before I do it I'll ask if anyone has had bad experiences with the kit, but I've read some raves about it already.

 

I've heard Drew mention that Walbro pump before and I think he too was pretty excited about it. One thing that I did like about that kit was that it came with 1/2" lineinstead of the 3/8" line that the FASS does. I don't know if that matters since I hear so much fuel being pumped back into the fuel tank, but I've always been a fan of Tim Allen's " More is Better" theory.

 

I understand the older trucks with the VP44 have lift pump problems, but what about my 04.5? Does it suffer lift pump problems and does it damage the injector pump?

 

That's a good question, what about the 04.5's - 07's. Is there any problems with injector or lift pumps on these years?

 

I don't know guy's.

For some reason I don't think you guy's have the VP-44, I think you have the CP-3.

The VP-44 is NOT tolerant of a fuel pressure loss at all and will die a fast death without fuel, whereas the CP-3I believe CAN handle it and will survive. I may be wrong so don't take my word on it, but I think that's how it goes.

 

So do the newer trucks need a FASS?

 

not unless you've got some mods done. The stock pump will feed the cp3 just fine until you start dumping more fuel into the cylinders.

 

the pump in the 3rd gen common rails is the exact same crappy carter pump the 2nd gen 24 valves used. are there problems. . yup. . .am I worried about killing my CP3. . .just a little, however it has the ability to pull its own fuel where the VP44 doesnt. also the CP3 is more tollerant of low fuel flow situations. it still requires diesel to cool and lubricate parts, however the internals are a bit more robust.

if your stock pump dies the dealer will replace it with one that goes into the tank. . .personaly, I would upgrade to an aftermarket pump that flows a bit more fuel.
