I just remembered I cruise at 1600 RPM at 55. Revised my post.
Lift pumps commonly went bad on the gen II trucks, but I imagine the issue was addressed on the gen III. I got a replacement OEM "campaign" lift pump for cheap, but discovered it had gone bad after less than 40,000 miles. Before I installed a fuel pressure gauge, I would only discover the lift pump had gone bad after running out of fuel and then being unable to prime the fuel system (no fuel from loosened injectors). I had to buy an aftermarket lift pump since the OEM was so useless. Fortunately I have never lost a VP44, which is $2,000 compared to the $150 lift pump.
Does CR even have a VP44? I imagine it's a different high pressure pump altogether.
