My bad thought you meant he rebuilds IP pumps.
Oh...for that, go to Test Calibration. Desirrah Dr is the first left off the I65W service road heading north from Moffat Rd (US98). 251.471.3777. They will want a core, and I wanna say mine cost like $300. That was a few years ago and a special situation: Diesel Injection Service

lied to me and forgot to rebuild my IP when they had PROMISED a one week turnaround...I was screwed, needed my truck working again, gonna lose my job, etc. So they sent me to Test Calibration and arranged $100 off the price of one their rebuilds. That IP has been a good little trooper throughout all my alternative-fuel exploits and although a Baby Moose would be great, a bird in the hand etc.
