Carter Fuel pump

[625fireman]

Anyone think, or tried one of these for 6.5's. Seems to read like it would work rather well. The only ? I have is 100 gph too much for slightly modified. Summit says gas only but Carter's webpage says you can pump diesel or just about any fuel through it. They have a couple different ones but this one looks the best to me.

If you are talking about a stock replacement carter lift pump, I have used one for 2 years now without issue. In fact, I am using it to supply my cummins aswell, I don't have my pressure guage hooked up right now, but with my 6.5, I never saw less than 2 PSI at WOT.

 

[Matt Bachand]

I don't think rotary vane pumps are flow on fail (always). Thus if a power/wiring problem, or pump failure, truck is getting towed. That or your going to be underneath the truck hacking/splicing to bypass that setup to get home on the IP's great ability to limp back home almost as well as if its fed with a healthy lift pump.

Also 8psi is too low IMO for a modified pump. Once it pulls through a prefilter, and pushes through the filter manager it will be down to 4-5psi at most. If spending coin and doing mods for upgraded lift pump, I'd want at least 8 going into the IP. Not that its necessary, but if giong through the hassle to mod the lift pump, why not?

Obvoiusly something adjustable is better, but something that puts out around 15psi would be closer to 10-12 at IP after the filters, if 14 is safe for the IP, then a 20psi pump would probably be closer to 14 after the filters. There are little options available however that are flow on fail with these PSI ranges.

Like I said above, its not even necessary as long as your not 0psi, but it must have a slight advantage, and it must make the IP work less if it doesn't have to suck at all.

Just my opinion.

 

[625fireman]

Nope its not a stock replacement pump. Sorry the pic didnt post earlier. As for the psi they have two models p4600($103.95)-hp is 8 psi (the first post) and p4601hp ($122.95) is 18 psi. both flow 100 gallons per hour. 3/8 fittings. Both prices are Summit racing. The 18 psi says it requires a regulator. But i dont think it would be need for ours?????

 

[Matt Bachand]

The 18psi should be close to perfect (IMO) with a prefilter and the flt mgr.

You would want to make sure your not feeding the IP more than 14 (thats a safe PSI from what I've read)

Also check into if its flow on fail. If its not. I'd plumb in a bypass with a easy to use valve.

I'd love to see you try it out. Be sure to run a pressure gauge plumbed between FLT MGR and IP to make sure your not juicing it too much pressure.

Thats a very fair price. I'd really like to see someone give it a shot.

 

[Matt Bachand]

Are they even rated for diesel fuel?

 

[625fireman]

Summit says no but Carter says it will pump almost any fuel including good ol #2.

That basic design Carter pump was used as a lift pump on a lot of the earlier 5.9 Cummins. It's a somewhat controversial subject as many failures of their VP44 injection pump have been blamed on failed Carter lift pumps.

You might inquire w/ Acesneights1 as he's got a 5.9 Cummins (he really likes) about that vintage & has prolly trolled the 5.9 forums enough to have the skinny on that pump type.

FWIW - the stock LP is rated ~ 20 gph, Walbro FRB-5 lost of folks have used ~ 45 gph. 100 gph is 5x stock.

Yep the fuel flow was my big concern too. I didnt know what the stock ones were rated at, thanks for the info. I was just curious bout these I saw them at Summit while I was there sat nite picking up my head studs.

 

[Jorge6.5]

Did you get the carter pump installed? If so how is it?

 

[625fireman]

No I never did it. TOO many other things came up. I am still runnin a stock one. Which sux.......
But i havent forgot about it though.........

 

[1999gmc]

Just wondering. But why not just get a Walbro for another $20? I put 2 of those Carter pumps on my father inlaws 01 cummins in 3 years. Got the lift pump from Carquest but when taken out of the Carquest box, it said Carter right on it.

 

[Jorge6.5]

From my readings, seems like the carter pumps don't last long on the cummins for some reason.

I have a carter oem style replacement lift pump on my truck for a few years now and it's still working great.

The carter pump can also be had for less then the walbro. The carter actually comes as a kit with a mounting braket, mounting hardware and hose fittings. Basically just need some rubber hose to plumb it in.

I have spoken to few 6.5 owners who are having great luck with the carter and have several miles on them. The walbro pumps can fail too.

The Carter put a small bubble stream in the fuel as seen from the IP return line. They do not tolerate Biodiesel as this ruins the brushes. They have a screen in them that is difficult to get to and clean. When it died (in under 2 months) on me I put in a Walbro and haven't bought a new pump in years for the 1993: I did have to rebuild it due to bad fuel, but...

 

[DieselSlug]

Wow, old thread. I put a used Cummins Carter pump in mine. I like it a lot! I think they fail on the Cummins from engine shock. I put one on my rig at least 3-4 years ago, no issues what so ever. A solid 14 psi at idle, down to 9 throttle. I did buy a spare because people told me i was dumb for wanting this pump, but its still on the shelf. You can get these pumps used from Cummins guys for 30-40 bucks!

 

[Jorge6.5]

I think I'm gonna go with the carter p4601hp kit, seems like a robust unit. I have already looked into check valves incase one is needed

Good to know they wont handle the bio...........as that is what I run, at least 10% most of the time.
Guess there are out for me!!!!!!

I had a Cummins pump gifted to me by Diesel Pro (Mike) back in the day, I used it for a xfer pump from my bulk tank to my main tank, it died, and when I opened it up saw the vane blocking the outletport. Confirmed with Mike that is what was killing many of the on engine pumps on the Cummins as fuel lubes those, and lack of fuel is bad ju-ju and why you can find those cheap from the Cummins guys when they upgrade. A flow on fail IMO is what you want in a pump, guys @ Hoesli Diesel Service in Evansville Indiana are the ones that turned me on to the Walbro pump, they recommended those for their Cummins customers as improvement over the OEM pumps.
