Ok. I'm starting to be concerned about my stock lift pump after reading all the posts about pump failure and such.

The stock lift pump is mounted on the block. Correct?

Do I need to remove the stock pump?

Is it electric and if it is, a vane pump or what?

I am presently having no problems with it now but am thinking my next upgrade should be a frame mounted electric with a psi gauge.

 

It should be on the drivers side of the engine block at the rear and it is electric. However if it isn't there the pump may have been relocated inside the tank by the dealer. If you don't have a fuel pressure gauge... how do you know there is currently no problem with it?

 

You can leave it on the block and just bypass it if you get a frame mounted pump.

 

I assume there are no problems but you know where that can get you. Currently the truck runs fine.

Thanks for the info White Lightning.

 

When I installed my gauges I was shocked to see I only had 3 psi at idle and 0 psi under a small load. My truck was also running with no problems including towing. I changed the pump immediately installing the same Carter pump on the side of the block and then had 11-12 at idle and 6-7 at WOT (full throttle).

 

Buddy of mine was heading out to do a pipe line and his 99 CTD left him dead on side of the road. Never saw it coming. Dealer diagnosed LP failed and killed the IP. They did an intake retro, against his wishes, but that's what DC says to do. If you don't get a gauge, at the very least put a low psi warning light kit on and have a piece of mind to know when the pressure is falling to the point of eminent danger. My buddy did and now his blood pressure is lower driving to a job.

 

If you put on a pump, spend a little more and go with a good pump like a raptor or fass hpfp. I don't even watch my gauge anymore because its so boring... 15.5 at idle and 10.5 at WOT...

 

As far as I know it's the stock pump. I better get one after a possible 183,000 miles. I went out and checked after work Busboy. There it was on the drivers side under a big canister filter. I saw a used Fass in the classifieds a while back without filters for 150. What does something like that go for new?

 

It seems you can spend a little or a lot for the various pumps but the MOST important item is the gauge so you can monitor the fuel pressure. It doesn't matter how good the pump is if the filter is partially blocked and it's starving the VP. I personally like "factory" set ups. When you break down in the middle of nowhere you can usually get a factory part. I used a Carter replacement pump Carter 4601HP. There was also one from Cummins part number for the campaign pump from Cummins is 4090046 but I'm not sure if it's still available.

There have been many threads on the subject of LP pumps, with many opinions. One thing everyone agrees on is the importance of the gauge.

 

The 4601hp are just as good as stock, JUNK been there done that 7 times all on warranty finely went to a fass and never look back

 

fass im sure is a good quality pump but what does that say for the airdog unit.
please advise
I dont have a psi gauge.
I contacted air dog and they say under no extreme the filter should last 30- 40k miles.
please advise

 

I wasn't actually recommending either of those "like stock" pumps, I was recommending the gauge installation. As for the life of a fuel filter, it can partially plug the minute you start up the engine if your fuel is contaminated. Only a fuel pressure gauge or a low pressure lite would tell you. When the engine does stop from a plugged filter in a way it's a good thing as it is no longer damaging the VP. I personally installed a "like stock" pump so I can easily replace it again and again. While I agree there are far more reliable pumps out there, when they DO break you will have trouble finding parts in the middle of nowhere. It's also much easier to lean over the fender to replace the stock pump than it is to lay down in the mud and try to find the frame rail mounted pump covered in frozen ice or mud.

 

If you want to stay with stock pump go for it its your choice pack a spare pump what ever it takes. Its like the fram commercial pay me now or pay me later

 

Mine went 103,000. I replaced it with another[cummins campaign pump] I bought an Airtex for a spare. If I am lucky I will go another 103,000 before I look at it. I am not into the myths and big dollar pump hype. They are prone to failure like anything else.

I know for a fact more oem lift pumps have been replaced needlessly due to mis-diagnostics, guessing, and Ill-advice.

 

From what I've read on other threads, a fass or raptor are the way to go. Anyone use a holly blue? Will get a gauge for sure.
