Well fellas, I got the truck back together. If anyone was around a couple of months ago I was the guy who had to take the passenger head off my 1988 7.3 to get an easy-out unstuck from one of the injector ports.

Today I was ready to start the truck again; I began to bled the injection system. I have fuel going to 6 injectors, except cylinders #6 and #8 (The two rear most cylinders drivers side)

I cracked the injector lines at the injection pump, and fuel wasn't coming from those two ports.

I have three options: 1) Rebuild it myself ( I have no idea or experience in this field) 2) Buy a new pump 3) Have it rebuilt at a shop.

I'm interested in y'alls opinion on the matter, and if anyone could provide me ideas, prices, or point me in the right starting point on rebuilding the pump myself.

As always, much appreciated

 

Just curious, was the pump working prior to you removing the head?

 

I've only had the truck running twice in the four months I've had it, all in the first 2 days of ownership. Both times I've had to use assist by a can of Liquid Engine Destroyer. Once the truck was started it would smoke and shake fiercely.

I think yes the injector pump was working prior to me removing the head, but still was starving fuel to two cylinders due to the obvious misfiring.

 

Ah fair enough. Well depends on budget you can find a decent reman which will be good, i use one. I would suggest replacing injectors at same time. Or atleast have them pop tested. If you want to try the poor mans trick, ive had luck soaking a bad pump in wd-40 and pb blaster then atf and running atf through it. Pump is still working. Wouldnt hurt to atleast try running some atf through the pump first.

 

Fill the filter with Diesel Kleen start or crank it into the pump and let it sit a day,IP's are not home rebuildable.

 

I could definitely try that

 

If worse comes to worse I found a reman pump from Diesel Care for $ 325. Taking into consideration that some reman pumps go for 500, am I getting a "you get what you pay for" with this? http://store.dieselcare.net/dbinpu.html

 

Check out pensacola diesel. For affordable stuff.i know there customer care is decent. Plus i dont believe they have a core charge on these pumps. It wouldnt hurt to contact a local shop and ask for a price aswell.

 

i've heard good things about pensicola, and about hectorwithinjectors on ebay.

personally, when i had my engine apart i sent a spare IP in to a local shop to get rebuilt, and $600 later i got a pump that was inferior to my old one. i don't plan to go back to them.

as others have said, you can't rebuild it yourself - you might be able to take it apart, and maybe put all the pieces back in the right order, but you'll never get it set up right without specialized equipment that nobody on this forum is likely to buy any time this decade.
pumps aren't available new, so rebuilt is your only real option.
depending on your budget, you might stop by your local self-service junkyard and see if they happen to have one - i got 2 there for cheap - and its at least worth a gamble.

 

I price checked my local rebuild shops, and I heard figures anywhere from $595 all the way to $ 1400. I went to a local junkyard and I found a F350 7.3 non-turbo somewhere before 1994.5. The tag on it reads DB2830. I went back home to check mine and it says DB2-4812. What does this mean, would it fit/work correctly if the numbers aren't matching? I also rechecked the DieselCare link and if I recall correctly it said 5013.

Pensacola had a pump for 395, but no four digits to compare to. I'm pretty confused right now.

 

diesel care, pensacola, dpc..... all cheapy remans that have little to nothing done to them other than cleaned up and resold.

Contact R&D IDI Performance to get a quality reman pump with a good track record and someone you can one on one interact with and answer all of the questions you have about the pump numbers. (you're way over thinking it btw on the numbers.)

 

when it comes to the numbers, all of our pumps are interchangeable. there were only small modifications made to the pumps themselves, none of which are critical.
i would guess the number was different for every year and tranny option, just because manufacturers like to change numbers like that, but they're all the same inside. grab the one at the junkyard and see how it runs - i guarantee it'll fit.

 

not true. 6.9 and 7.3 are different pumps, and certain pumps used different shafts/seals and bushing/bearing.

All bolt on, but not all are the same and knowing what you have before contacting a builder is important.

 

The fuel system is the very heart of your engine. The health of the IP and injectors, as well as the timing and integrity of the return rail components will completely determine how well your engine runs, how much power it has, what fuel economy you will get, and what kind of stress you put on the rest of the engine. Basically, the fuel system is one place you don't want to skimp if you can help it. We all understand being short on cash, and sometimes a used junkyard pump or cheap-ish rebuild is all you can afford. It will get you back on the road, but if you want to run the truck for a long time to come, invest in a good pump. The price difference is not so much more than a cheapie one, and it will pay you back in longevity and performance. R&D sells theirs for $570, and it is a quality part. By comparison I spent almost $400 at Autozone before I knew any better, for a junk pump with a 90 day warrantee that runs, but with lack luster performance. A lot of owners are happy with their Pensacola's, and compared to the shot piece of junk they took off it works great, but if I was going to drop that much, I'd hold out and drop a 'lil more on a good one... just my .02

 

I've tried to run Diesel Kleen through the pump for two days, even sprayed carb and choke cleaner down the two nozzles that were not spraying fuel out of the injector. I considered the carb and choke drying out any rubber gaskets, but I figured the fuel may lubricate it again, and if It didn't lubricate then the pump was already trash.

As per your recommendation I tried to contact R&D IDI, but I never got an answer from the guy. I then called up Pensacola, talked with the guy, basically asking him about the pumps, numbers, what they do, who they send the pumps off to (if they do), etc. He told me that they clean the pumps, tear them down and replace the moving parts and that I was getting a new pump included with a one year unlimited mileage warranty. He said that the pump they sell is a Boss pump, and that "they don't deal with Stanadyne junk". The biggest winning factor here was that the gentleman said they had the pumps in overstock, so they weren't even going to do a core charge, which I'm more than happy with. I can't believe I'm saying this but it seems $395 can't be beat for a numbers matching pump. I will update in a few months how the pump is fairing me. I appreciate everyone's input for sure.

I can also add that I asked him if the pumps were interchangable: 5013s, 2812s, 4821s, etc, and he told me that ultimately they were not because they all carried different inner parts. <-- Just to add perspective on this topic.

I did read up that dynamic timing is best left to a shop (I'm not buying the tools to do it myself, I'm strapped for cash as it is). Can any ol' local diesel shop time a clacking IDI correctly?
