Was there ever a p-pump application for this beast? I've seen many busses with ve-pumps utilizing them, just wondering on availability of factory p-pump injector lines. Reason I'm considering it is because I already have one, and would like to get my truck together (OBS f350) and all other plumbing/wiring sorted out before I start hacking the core support up for air/air. Truck is bare frame from the firewall forward at the moment.
