Diagnosis: Injection pump rebuild ... $1,100 ... ouch!

[FinnJohn]

Hi guys, I have a question for you again. I searched the forum but couldn't find anything on it.

My injection pump is leaking diesel all over and I just got word that it's pretty much a basket case. A local outfit wants more than a grand to go through it, but I'm seeing several of them on eBay, used, for $100 or $200. Do these fail a lot? Is it a bad idea to take a chance on one of these used ones? Or is there a source of rebuilt units that cost less than $1,100?

One other thing -- will veg oil ruin IPs? Do I need to worry about whether a used IP comes from a vegmobile?

Thanks!
