i have air bubbles in my fuel return line, the clear one that goes back into the IP. Usually you don’t see them until you tap the start of the line down near the injector at the front driver side. It has screw down clamps on the hose, tightened those to see if it would help and the bubbles didn’t go away. What was weird was, when I started the truck, it started with no problems, but the bubbles went from the connection with the IP, back down to the injector. The truck ran for about 10 minutes, didn’t bog or throttle at all, then I killed it. Bubbles again came up the line when I tapped it at the base connection with the injector. Can anyone tell me where it sounds like I might have a leak? Someone definitely replaced the return lines at one point in time, but I don’t know when. Probably going to buy a return line kit, to see if that fixes the issue but it wouldn’t hurt to get some input on it. I’m somewhat mechanically inclined but I’m fairly new to mechanic work, definitely new to diesels and the 7.3. Thanks.
