Lift Pump Time - You Guys are not Crazy

[SnoKing]

I ran the stock original lift pump later moved to frame rail with Geno's Vulcan kit, and finally replaced with my spare when I installed the new VP44 at 52K. Well last month while on our way to Arizona the replacement started to acting up with intermittent low fuel pressure. So this morning I reinstalled the original pump while I decide on what I want to do.



I would like to keep the stock heater/filter finding a replacement to mount on the frame where I currently have the stock Carter pump. I am at around 325HP and 650-700ft lbs and will not be changing that, so I would like to just install a pump with the existing lines. Suggestions? Air Dog 100??? Small Fass??



Oh! And I have to say I kinda thought you guys just had bad karma or something with all your ranting about the Carter pumps. Sorry! This second Carter went less that 20K and less than 2 years.

I put on a fass HPFP when I put the new injection pump in. Got mine here, it still runs the stock heater/filter, and works great. Source Automotive Performance Diesel - HPFP 95gph Fuel Pump for 98. 5-04 Dodge Cummins 5. 9L

For an inexpensive option you can install the Aertex pump that has been modified by Eric at Vulcan. This is a good pump for stock and fairly stock trucks. I put one of these on my wife's truck.



Vulcan Diesel Performance offers DDUSA twin turbos, FireBall injectors, DrawStraws, Big line kits, FASS fuel pumps, Parker bio fuel line, Quadzilla products, DTT Transmissions, Isspro gauges, High Tech Turbos , Veg pumps, metric adapters & fittings,



With your mods, I would install the Air Dog 150 and be done with it. You can route the fuel lines through the OEM fuel filter canister and still retain the fuel heater or you can pipe it direct to the injector pump and install an after market fuel heater.



I will be installing an Air Dog 150 in the near future (Santa Claus was generous this year!) I already have the Vulcan 1/2 inch big line/pump relocation kit installed and plan to route through and use the OEM fuel filter canister so I can retain the fuel heater. Extreme Diesel has the Air Dog 150 on sale for $499 with free shipping:

The Air Dog is quieter than the FASS and comes with a life time warranty. Both the FASS and Air Dog are great pumps.

 

[blacksheepdiesel]

The small AirDog is more than sufficient for both of you. When you choke down either AirDog by running it through the stock filter/heater you simply create more fuel bypassing into the tank from the AirDog which serves absolutely no purpose. If you insist on having the stock filter/heater just go with the smaller AirDog.

Godspeed,

Looks like I might be down to Airtex, FASS DDRP or Air Dog Raptor after a bit of reseach. Sure wish wifes understand all of this and the cost! Why is our truck needs all of these expense parts, is what she is asking! SNOKING

You sure the screen that surrounds the intank fuel module isn't starting to plug up? I always get suspicious when I hear of mutiple failures. You might want to pull the fuel sender and check the screen. I know it's a PITA to drop the tank and all but it might be worth it before installing a new system.

[Erik@LCD]

FASS DDRP is a great solution for your situation. You can also run a small FASS or AirDog 100 through the filter cannister to retain the heater. Just remove the element.

 

[Allnew2Me]

I had two failures in 10K and that was enough of that. I installed a Fass95 back near the tank and no more problems. It has been flawless, the FASS is quiet and reliable.

At less than 70K on the clock and having never had a Fuel Filter that showed any sign of dirt, I doubt that the screen is an issue.



For the record the old original pump is back on and putting out 14 lbs at idle and 10-11 at WOT. Only the second pump actually was showing signs of failure, dropping to 5 lbs a couple times, then going back to 14-15 on a restart. I have lost trust in this second pump. I will most likely take it apart after I put another new pump on it and look at what was going wrong with it.



So it will be some sort of basic after market pump and the original pump will go back to spares. With hose barbs pre installed on it, it is less that 10 minutes to swap it in. It is not like a put a lot of miles on the truck.

I doubt that your problems were caused by any debris in the tank or pump, just the usual lousy fuel pumps. I had relocated mine to the frame rail near the tank thinking that was the cure, and it did show more pressure with a low tank, but they still go out and yours will also. I was stubborn and thought everyone else was wrong until I had another one go out after only 6000 miles and got tired of buying $130 pumps.

I also cut one apart and they look perfect inside, no crude or anything that would indicate failure, in fact the 4 I had to play with all ran fine on the bench but wouldn't produce pressure on the truck.

 

[Shelby Griggs]

I would put the FASS DDRP on, there is a replacement bracket available for the frame mount location (the Vulcan relocate kit one is too wimpy). Will bolt right up to the rest of your Vulcan kit and that should solve your LP woes. I just did this, don't have enough miles to know anything about it yet, but I am hopeful! Much quiter than the OEM Carter too.

I moved mine from the stock postion to the frame rail with the kit from Geno's. I had intended to continue using my stock pump with 100k on it, but I messed up the studs removing it. Stock pump was still holding 10psi and I wanted to see if moving it helped any. I used my spare, and it pegs the fuel pressure guage. I was wondering if the new airtex could be mounted on the frame rail? I would like to get one for another spare. JC

 

[SnoKing]

Vulcan has a kit for the frame mounting of the Airtex pump. However it repeats a lot of the parts. Waiting to hear if the engine mounted one will just fit down on the frame. May need one longer piece of hose. SNOKING

 

[Chief USA]

The Aertex pump comes with the bracket on it already and bolts to the OEM bracket on the side of the engine just like the old Carter pump did. It should bolt onto the frame bracket as well. You will need a modification kit for the Aertex pump so you can attach the 1/2 fuel line and AN fittings. Vulcan sells that as well. Don't forget that the Aertex pump requires a 70 micron prefilter to be covered by warranty.

 

[SnoKing]

I ordered the Airtex E8845, pre-filter and a foot of hose. I unbolted the Carter for the bracket, removed the bracket and drilled holes for the Airtex pump mounts. Reinstalled the Vulcan frame bracket on the rubber mounts that I made and then moved the hoses over to the Airtex with minimal fuel leakage.



For the wiring I took the short jumper that comes in the Carter box and cut it half. I matched up the colors for correct polarity to the pump then crimped and soldered the ring connectors to the jumper. This allows me to plug the Airtex into the Vulcan relocation wiring harness. Also I can in ten minutes or so reinstall the Carter if I have to do that.



Pressures. Before with good Carter.

Idle 14. 5

Cruise 13

WOT 11

Airtex

Idle 19. 5

Cruise 16-17

WOT 11



I had to look at the E8845 closely to find the plus and minus 12V markings. Looking at the end with the outlet up, the plus is to the right and minus to the left. Markings are on the white plastic end cap.



Pump outlet is the end with the 12V connections.



It took me about an hour to install in a RV park in Arizona with minimal resources.



Will not be able to tow until April 1st, so no report there.



It is very quiet! And hopefully will last a long time.



Cost = <160

I got similar results with the Aertex 7153 pump Eric modified for me along with the Vulcan 1/2 Big Line/Relocation Kit which I installed on my wife's truck.

 

[VolsFan]

I just installed the DDRP on my truck today. It wasnt too bad of an install the hardest part was drilling the frame to mount the new bracket, but it is in the single digits here and had to do it outside. I am very pleased with the results. After sitting for two weeks, the truck fired right up after being primed of course, and the pressure gauge went right to 20 lbs. I drove it around town and I couldnt get it to go below 15 psi at 35 psi boost. I ordered the whole setup at Vulcan and would reccomend them to anybody. My carter went out on new years eve and i order one on new years day. I knew it was a bad time to order one, but after a week or so I called and talked to Eric, and he had one sent out right away from Kentucky, as he was awaiting a shipment of DDRP's himself.

 

[JMetzger]

I have always had good service from Eric at Vulcan.

The Walbro I installed 10K miles or so back has been running great so far - with the restrictive Frantz fuel filter and my homebrew regulator/bypass valve, PSI holds steady at 15-16 PSI in most driving situations



The OEM Carter that was moved down to the frame rail is disconnected from power, but still there in case the Walbro goes TU:

I'm still running the 7 psi carter pump on the frame rail that I installed in June of 2001 at 60,000 miles and I now have 240,000 miles on the truck. I had to replace the engine mounted 15 psi one at ~200,000 miles (it lasted 140,000). Prior to that I went through 4 engine mounted pumps in 60,000 miles. I've been very happy with the two Carter pumps in series.
