The Story

Bus doesn't run right now. It was my daily driver until last year, then it quit and I haven't had time to track down the problem.

But the expensive stuff is already done... new fuel pumps, filters, hoses, belts, and the whole fuel system's been gone through.

This 7.3 diesel is the kind you can fix yourself: no computers, no sensors, just a good engine you can turn a wrench on.

Lots of folks out there who know these buses inside and out.
