Also, approx. how high is the lobe on a B/RB cam that actuates the lever on the fuel pump? (Oh yeah, something's very worn...) Thanks guys! 2005 300C Hemi 2014 Ram ProMaster 2500 I Rekey, Repin old Chrysler locks and cut keys by code

Took us a while to figure out what was going on, until I posted on this site a few years back and someone came back with in minutes with the answer. Very common... 1999 Dodge 3/4ton Cummins 24 Valve, 4x4
