I have a 1982 c20 with low miles and what appears to be the original IP do you recommend running it till it fails? or should I swap it out for a rebuilt one? I see there is a place on EBAY that you can buy a rebuilt one for $265....

thanks for advice.

Personally, I'd just run it until it fails. My pump has been failing for many miles and is still running...

Seems you've gotten all the relevant details on your last post - the rest is a matter of personal choice. If the pump is actually original and untouched - it can die quickly and leave you dead on the road somewhere. That may, or may not be a big deal.
If it's an 81 to 85 pump that has already been updated, or a post-85 pump, such failures are rare - the later pumps wear slowly unless you run water, bad fuel, or too thick WVO - which can shear the drive-shaft and ruin the pump instantly.

I'd question any "rebuilt" pump for $275. Call first and find out exactly what parts have been replaced and/or updated. "Rebuilt" injection pumps do NOT get all wear parts renewed - like you'd do with an engine. Some rebuilders put in more new parts than others. I've called a couple of Ebay sellers who sell "rebuilt" pumps and injectors - and after asking specific questions, I did not like the answers and chose not to buy.

thanks for the warning on the "rebuilt" pumps....maybe I am better off just getting used ones and keeping a spare. (do any year 6.2 pumps fit or do you have to change some things (injector lines?) mounts to motor?

I looked at my pump in the truck and it has a black and white metal id plate and shows that it was the 1982 HD version.....it is hard to read one half of this plate when in the motor....where do you think you would typically see a metal tag added after an update? and if that isn't there do you think I should open it up to look for little chunks of plastic??

The update tag would be on top of the pump, held in by one of cover-screws. I don't think anybody has used those tags in years, though. I suspect the mentality is now - that no pump that hasn't been updated could still be working - so no tag needed. And, that's true for a pump that's been in use - but not true for something that has very low use and miles.

Any DB2 pump from a 6.2 will fit - but there are many subtle differences, e.g. the advance curve, the size of the delivery valve, "Artic hardened parts", fuel delivery rate, and exterior components, i.e. the VRV vavle or the TPS.
