The Holley Blue pump that I had installed on my 1999 Cummins truck just took a dump, for the second time. Here is a little background on what has been done:
When my original VP died (in ’04 or ’05) and I replaced it with an Industrial Injection Hot Rod VP, I also installed a Holley Blue pump on the frame as close as possible to the tank. I wired in a dedicated 30 amp relay, triggered by the original LP power wire, to power the pump. That Blue pump lasted until last September. As that Blue pump was used when I put it on (I know, I know, but it was laying on the shelf), I chalked it up to age/wear. An autopsy revealed that the armature was really worn and had 2 or 3 burnt bars.
So, I purchase a new Blue pump from my local O’reilly Auto Parts and replaced my old one. Good pressure (after “adjusting” the relief spring) and quieter operation made me a happy camper. Until about 3 days ago when I started my truck, went about 50 feet down the driveway, and noticed that I had no fuel pressure. I stopped, shut off the engine, and tried cycling the key a few times. After the 3rd or 4th try, the pump came back to life and the pressure returned to near normal. I started the truck and continued on my way, eyeballing the gauge about every 3 seconds, but other than the pressure being a little (2 or 3 psi) low, I had no other problems. Until this morning that is…I start my truck, everything is normal and I take off down my county road, make it about a ½ mile and no fuel pressure again. I stop, cycle the key several times, no pressure. I unplug the relay, scrounge a piece of wire and jumper the connector. I crawl underneath and peck on the pump and it starts running, sounding like crap I might add. I turn around and head for the house and just make it to the driveway when it quits again. I can peck on it and make it run, but it sounds like crap.
Of course, Holley only warranties pumps for 90 days. But I’m really kind of hesitant about putting another Blue pump back on it if they won’t even make it a year. I had it in my mind that I wanted to try one of the Edelbrock/Essex pumps until I noticed that their warranty is void if used with diesel fuel. So…what other options are out there…without spending $500-$700 that I really can’t spare right now?

Thanks!

 

the original carter lasts a lot longer than that......i have had a campaign pump on the frame for at least 5 years and it's still going strong

 

go with a fass ddrp abt 250 dollars 18psi idle 13 - 14 wot mount on frame not stock location had mine abt 1 yr no problems i think they have a 4 yr warranty

 

Becareful with the fass if you get one that has the filters they are hard to get replacements for. I am having that trouble now They had fleetguard make them a special filter that dosent cross to anything else.

Jason:

Sorry to hear about your Holley Blue Pump. FWIW, I ran a Holley Red for over three (3) years on a 2002 Dodge CTD 24 valve that I had and never had a problem with it. It was still on the truck when I sold it.

I would recommend another Holley to you, but I know you are probably "gun shy" about them now, which I can't say I blame you. If you do get another one, go to "Advance Auto Parts." On the Holley Red I had they offered a one-year warranty at the time I got mine. I also saw a nice fuel pump from "Mr. Gasket" in their store about a week ago. I think they were about $100.00 and the sales guy said they can be used with diesel fuel too.

Goood luck Sir!

Here is the link to that "Mr. Gasket Diesel Fuel Pump" from "Advance Auto."
They are cheaper than I thought. Only $60.00 on-line:

Couple of things to consider. What gauge wire did you run to the pump. Make sure it's more than adequate to handle the current/load. Do you have a pre-pump filter...this will make sure the fuel into the pump is clean. With a pre-pump filter remove the plate on the bottom of the pump and take out the brass screen. If no pre-pump filter this screen could be clogging up placing added strain on the pumps and causing failure. This has worked flawless for 2+ years now. JMO.

 

Well, my truck has been sitting and I have been saving up for a decent pump.
I was thinking pretty strongly about getting one the AirDog pumps that the DTR store has on sale. It seems like the most "bang-for-the-buck", as far as pump, filtration, etc. I was considering a FASS HPFP ADJ 150-1003, but seems like for another $50, the AirDog looks like the better deal.
What do you think? Is there another choice for $500 or less that I'm missing? Does the AirDog, that the DTR store sells, come with all the installation hardware? Is there anything that it doesn't come with?

 

I think the reason I've had good luck with the Holley is because I've always used it as a pusher pump behind the stock lift pump. The two pumps share the load of getting the fuel out of the tank.

 

Put a walbro 392 on the INSIDE frame rail just in front of the tank with a pre filter and never look back. Cheap and very easy to do. For the cost of the air dog you can get a spare 392 and throw it in the glove box and if you ever need it about a 5 minuet change on the side of the road if you install it right.

Walbro has been the OEM on many vehicles for many years not this particular model but you get the idea.

I had put a new carter back there and like your holley it took a dump after a year as it has to many others seems to be very few have had a walbro take a dump none of them are always perfect.

 

Man, the price is right, but, do you think the Walbro would flow enough for my application? 50 gph seems like it would be borderline...

 

These are positive displacement gearoter style pumps and they move some fuel.
When i first hooked mine up without the by pass/return circuit i just tapped the power wires together for a couple of seconds to purge the system and test the pump and almost blew the needle off of my gauge

In other words they really move some fuel and if you look at the specs can do it at somewhat of a high pressure much more than we need. 450+ HP should not be a problem for it.

Did you install larger lines and at least drill out the banjo bolts this helps with the flow volume.

 

I installed my walbro in May '07. 3 years later I have put 51K miles on this pump. No issues to date. Still idles at 20 psi and pulls down to 15 psi at wot.

 

Hi guys, I just had gauges (fuel, pyro, boost) installed on my 2000 Quad Cab w/6 speed and noticed my fuel pressure at 7-8 psi at idle and dropping to 3 psi when I step on it. My only mods are a BHAF and MBRP exhaust. I had the original fuel pump(and injection pump) die under warranty and had it replaced a couple of years ago. Could this be a filter problem or is the stock pump that weak?

 

Could easily be that the stock pump is that weak. May want to change the filter out also. If you still have the stock LP, you should really think about an upgrade; although few have had good luck w/the stock LP. 3psi is not enough, IMO!
