Is it not getting enough fuel through it? That screen in my tank (mixer) has been there for 291k... I'm planning on doing the in-tank mods soon. I'll bet that'll help some. But I definitely think my pump's gonna crap out!
You have the stock pump and have NO issues with maintaining steady PSI on the injectors? You're running higher than stock PSI, right? I just don't want to have what's happening to Joe happen to me.
still on stock pump for now but my bowl is deleted..i have the adjustable regulator (right behind the alt) and its set for 62 psi but drops off at WOT...
mine is silent, I hate to replace it but with my setup im designing, I need a screw type fitting in the rear for my -8 hose to go into.
the stock pump has the quick fitting, that I can not find an adaptor to fit that goes into a flare type fitting.
Just an option, when I was running into all sorts of fun with my pump/in tank mods, I found out ( at least per the part number and description ) that the 5.4 pump was in tank. If that is in deed the case, then I would suggest the 5.4 fuel pump, this would help reduce air in the fuel lines. There was plenty of supply per the speck sheet.
If you need more info, I will go and look up my old thread and see what I can find. but just another option for ya.
who has had problems with the walbro? mine still works perfect!
My Walbro lasted about 3 months. Left me stranded 100 miles from home on a Sunday afternoon. I searched 5 different autoparts stores in the town I was in at the time and no one had a pump in stock. One parts store finally had one and I changed it out in the parking lot. Could have been a fluke, but the company I ordered it from wouldn't honor the warranty even though I hadn't told them I used it in a diesel. They kind of gave me the run around so I chalked it up as a lesson learned.
My walbro quite on me, I was able to send it in a get a replacement but that one died in less then a year too. So I went with a FASS HPFP, no problems, works great. But it is very loud.

What is the 5.4 and would you please?
I am seriously thinking of doing a dual pump setup, after all I am as dependent on my truck as the rest of you and as dependent on my truck as my fish are on their water and they have dual pumps.

That is good to know, I choose my products based on customer service, which BTW, as a computer tech I have had the BEST customer service from EVGA and as a back yard mechanic, from Clay at RiffRaff Performance, Here's to you clay for putting up with me!!!

What I find odd is there's this late-99 at the body shop and you can't even hear it's pump... AT ALL!!! Mine has what you guys call the "mad bees" drone. Then add that stupid chirping and it's ridiculous! Is it supposed to be that loud?
Your fuel pump is starving for fuel.
Pickup screens are clogged and restricting fuel flow.
I got rid of mine altogether and put the fuel pump at the end of the fuel pickup.
ZERO issues for three years now.
It's a Bosch 69430.
If you decide to do this, you need to peel off the plastic sticker that is applied to the outside of the pump.
The sticker won't melt in the diesel, but the glue that holds it on will and it will end up floating in the tank.
I found that out when I dropped the tank back down to check on things a short while after I did this job. Had to fish it out of the diesel fuel.

So if you have a pump failure will one pump keep your truck running? I'm thinking dual pumps for redundancy and that extra pickup that is obviously needed.
