[QUOTE="brewer, post: 598240, member: 348"] Not too long after I put in my DIY efuel (SD pump, RR, etc.), I started getting a pinging sound (like a rod knock sound) from my passenger side. I've also noticed over time I've started getting some oil in my fuel filters. It runs rough (shakes pretty bad) at cold idle (pinging gets quieter as the truck warms up) and gets bad mpg. I've tried unplugging/plugging the UVCH with no luck. Still have yet to do a buzz test. I've also looked up youtube videos of it to see if I can match the sound to someone that's had the same problem, which seems close but I can't tell enough from those videos. As I've been doing some research, it sounds like I've lost an O ring? Truck has 146k [/QUOTE]
