Trying to identify manifold coolant sensor
The original owner had it converted from a 6.9 to a 7.3. Maybe they installed the 6.9 manifold onto the 7.3?- jax1463

Air Intrusion ..... Stumped!
I have replaced my return lines, injector O-rings and the line to the injector pump. Checked all of the fuel lines back to the tanks. Can't find any seeping or loose connections. Anyone here have any possible idea where to look next?- jax1463
