Bernd completed the mission
I finished up at Bernd's today with mission accomplished. I went in for new fuel lines, resonator, and while on the way from Arizona, both my oil pressure dash gauge read 103 ( pegged at high end) and my VMS-PC. Bernd thought it sounded like a bad oil pressure sender and we would replace it. Easier said than done.
Cummins told them that they no longer make the sender and have a new one which is a simple on/off type of sender. If hooked to the dash gauge it would read either about 45-50 or 0, on or off. Also, to install the new sender, a new wiring harness and reprogram the ECM was required- not acceptable. Bernd did not accept Cummins solution and talked a little up the chain until he got someone who could give him the correct part # ( same one the folks with the 5.9 Cummins use). It was in stock here in NAC the whole time, just needed the right part # and Bernd to shake them up to get it. Installed the sender, plugged it into my existing harness, both gauge and VMS-PC are reading correct oil pressure. Thanks Bernd.
Coach runs and idles very well now with the new fuel lines,and the Racor700.
Resonator looks good, sounds good, runs good ( just a short run around the loop so far).
Overall- good work.
