Folks With the Carter P4070 "lift pump"
So who all is running it, for how long, and any issues? I went onto summitracing tonight, and it says its for a gas application, while the carter GP4389 is for diesel applications. I definetely want longevity, its a DD that gets 30-40k a year on it. Both seem to have the same info, just the GP4389 is techically for diesel use, and approximately $40 more. They both have the same picture aswell. So, whose got info?

I went with the 4594 instead of the 4070 because it had a slightly higher output pressure (couple of psi) and I couldn't get anyone to tell me that it would be a problem - exact same price, too.
Anyway, I've been running it since late summer and haven't had a single problem with it. I've got about 7-9K miles on it at this point.

You got it, Nic. Really shouldn't be necessary if you have a healthy stock pump.
I chose to go that route myself because I over-engineer everything and had no data on the stocker (The Carter pump gave me some "suspenders" to go with my "belt"). Once I get my in-cab fuel pressure gauge hooked up, I'll get a better picture.

No problems here. I installed the Carter 4070 lift pump and a Carter 74221 high pressure pump. I shimmed the FPR to 68psi. Little noise but that lets you know it's working. I just installed a Fuel Pressure gauge in the cab, solid 68 psi all the time.
I have about 40k miles on the set up so far. I have the Racor 500 FG turbine filter between the tank and the 4070.
Just to make sure all was working, I took the hose off the intake side of the HP pump and the little 4070 sends out a nice solid stream of fuel.
