Just out of curiosity, doesn't the 7.3 have a mechanical fuel Injection pump?. ...if so, how does it prime with air in the lines?

Damn I wish this had popped up a few weeks ago when I was in CO. I have a hard on for OBS PSDs. I've paid that much for a running one, but if the truck's in good condition I'd say it's definitely worth negotiating with him.
If someone here buys it and keeps it in decent condition, I'll buy it from you when I get back from Trashcanistan.
The 7.3 uses oil pressure from the high pressure pump to activate the intensifier piston in the injector. A stock injector will have a 7:1 ratio so with 3000 psi of oil you have 21,000 psi of fuel coming out the tips. All of this happens inside the injector body. Fuel pressure between 40-70 psi is all that is needed to feed the injector. Hope that helps.
I thought you meant the seller himself. I've met more than a few people whose gears were a tooth off.
Great concept by International but it was designed for low RPM torque. Not a problem unless you want to build a high HP motor with it.
