As far as I know only the Ultra Lights and Phantom lines offer a HPO gauge for Autometer or do others now??

For fuel pressure you'll NEED a pressure snubber (Autometer #3279 or 3227) or you'll toast the sensor if electric or gauge if mechanical. Learned this one the hard way. Second, powerstrokes like to kill sending units from the vibration. I remote mount them on the firewall to isolate them when I do the installs. Got sick of warranty claims.
