You really need to know what your doing. I have been around here 10 years or more. Only heard of one guy on here that successfully rebuilt his. Now they can be done. Thepumpguy has rebuilt several here in the last few years when they have been needed for folks on here. He offers a mail in type service on your pump.

After following along on the guy who did his, it's no wonder most people send it in. All kinds of small parts and intricate assembly of parts. If you have done one before or been into that type of thing, then you probably can do yours as well.

I know it痴 not what most do, but I have more time then $$ so though what the ****, we won稚 ever learn how to do something if we don稚 try. Thanks for your help and time.

This is uncommon. I've been around on here a few more Yrs. than Clemsonfor and I think there has been but a few Inj. Pump problems. At least you found the problem or Pump problems. With that being said it almost sounds as if someone may have been in that one!! Don't get frustrated you got it!! It just boils down to Repair the Pump or Replace it. If it is Repairable? Personally I'd be hot under the collar also and it would be my luck that it even being so rare it would be mine that done it. I seriously would check into replacing it. Something Stinks!!!!! I would almost bet money someone was in that pump. JMO......

I think your right on someone has messed with it. I have found a new pump for about $100 cheaper then getting mine rebuilt, so I thought I would take a look at mine and see what痴 up with it,and if it is to hard for me to fix, then just get the new one and all is good. Thanks for your time and help.

THAT pump is NOT a good one to cut ur teeth on.!!
Your best bet is to send it off.. & DONT open it up..
Hoye "might" have 1.?? but you'll pay more for it, than getting yours remaned.. {depending on WHERE/WHO u send it to.}
My "guesstimates" are for a pump that hasn't been touched by the customer..
If I get 1 in "bags".. the price changes..{lost, broken parts}
& if it was EASY, everybody would/could do it..

Hey thepumpguy,I appreciate all your help with this , I have a hard problem sending something mechanical off to get fixed when I haven稚 even looked at it myself to see if it something that I maybe able to fix my self, that痴 what I do for a living 擢ix things but when I look at something and see that it is over my head,I then have no problem sending it to the guy that does that stuff.
Thanks for your time and help.

The 2210 Fredricks Refurbishes. My parts only show the bleeder Screw Assembly which that's not good. Only a hand full of models is on top of that which they do Refurbish also. They maybe who you need to talk to for Parts or Pump Availability. My guess they have the pump...

I will have a look at them.
Thanks for the help.

Seeing bubbles in the line doesn't mean much, most diesels will have a small amount of bubbles in the line, you will beat yourself to death chasing them.. Vapor bubbles are normal to see in a diesel fuel line..

But I知 getting crazy amount of air bubbles at the injectors, I do feel like I知 beat myself with this.
Thanks for your time and help.

Only thing I would check if you haven't already is to make sure you don't have a vacuum problem in the tank starving it of fuel, open the cap and run it to see what happens..

I haven稚 checked this, but I will, I did put a new cap on the tank, maybe you are on something with this.
Thanks for your time and help..

To check it you don't even need a new cap, just leave your very loose or off while running it, or not even finger tight but on the tank. That's all you need to get it vented. It sounds as if you can produce the problem with it stationary. I would just loosen the. So one turn from how you have it on. This will give it enough air.

Make sure that you have the rubber gasket in the cap. It should have a little groove cut in that gasket that will allow air to get into the tank and not make an or tight seal. But if you crank the cap down more than just barely tight this cut will get closed up by the force of cramming the fuel neck upninto that gasket from over tightening.

I will try this tonight if i have time. Thanks for your time and help.

So I did a little test tonight, I didn’t have much time, the fuel line looks basically bubble free now with the cap loose but I’m still getting the bubbles in my fuel at the injectors. I apologize for the shaky video . What do you guys think?
