My shade Tree mechanic has been installing an engine 2005 Colorado 3.5 Auto trans into my 2006 H3 adventure Manual trans for a while now running into problem after problem, we are down to our last issue before starting it back up,, seams the Colorado engine has a fuel pressure regulator that has no where to attach to the hummer, any thought or solutions out there???? the auto parts store assured me this would be a straight forward swap.

 

Swap the intake, fuel injector rail and TB from the Hummer to the Colly motor. No more FPR.
