Diesel Injection Service, now in Colton CA, 909-885-0590 did a great job on my pump just a little over a year ago. She runs like a champ. Give them a call, I'm not sure how it work for someone out of state. I took my rig into the shop, couple days later back on the road. A little pricy, but good work done in there antiseptic pump rebuilding room. You may mention my name/truck (Patrick Tavarez, '93 DodgeCTD, dark blue), as one of there satisfied customers if you think a reference in in order. Maybe they can recommend a quality shop close to you.
Hope you get your IP built right, the 1st time.
