I've rebuilt my engine for an engine swap, but I haven't touched the pump other that taking it off and setting it aside. It's been sitting for about three months now and will probably be sitting until late spring. Should I worry about residual fuel in the pump gelling? Is there a way to clean it out? The engine ran fine when it was pulled from the donor truck, but I know diesel fuel is not very stable.

There isn't enough fuel in there to worry about. As soon as you get it hooked up and purge the air from the lines it will be gone. What little there is is needed to keep the innards lubed. Leave it and cap the ports.

Awesome, thanks. That's a load off.

Diesel is not stable? well we just pulled a Bus out that has been sitting for 6 years and put batteries in it and started it up. Same fuel...same everything. We cleaned it up and it is on a route now. Stills runs great and it has a 8.3 in it....I dont think you have anything to worry about.

Just to add a little input, our 4020 john Deere sat for 2 years and when I got it cranking again it had bad fuel

A friend of mine did a salvage job on a WWII barge that had over 2000 gallons of 50 year old diesel in it.
He used it for a couple years in pickups and semis with no problems.

Maybe it depends on the quantity, where it came from, winter mix or summer mix etc etc I guess it just had bad diesel. I'm gonna have to buy me a barge!

Jim at northern factors (bosch fix-it guy) claims six weeks tops for a pump when out of the rig. He will buy cores from wreckers only if they are less than 6 weeks out of the rig, for market value.
otherwise he pays 50 dollars. for p-bosch p pump and will reman them.

You believe that? Sounds like a good way to lowball someone out of the rightful value of their pump. I bought an engine from a guy who had been storing it on his open porch for over a year. It had a fair amount of good Colorado dirt on it. I cleaned off the dirt, pulled the pump off and installed it on another engine. Timed it, primed it and cranked it up. I put about 5000 troublefree miles on it before I pulled it off for resale.

i dont have a sure way to tell if Jim is straight with me. He does all of the Bosch work for this area, and he does have a good reputation. And i have had dealings with him that have been all good. I phoned him on this issue, as a rep from a local truck salvage yard. It was an industry to industry call.

Please notice that I only quoted a professional in the field, and i did state that this condition is once the pump was off the engine or was opened up to the atmosphere
It seems more accurate to try to get professional opinion, or better , some facts involved on these posts. hearsay and antecdotes don't mean much to some poor fellow trying to learn about these machines.
