[Caleb Crisp]

Hi. I have a 91 7.3 sat for a couple years was running good and sprung a air leak. Should I start with injector return?

Welcome to the forum.More information on this air leak is required to better help you. In the mean time look at the return line caps.If any appear to be wet then yes. Replace them. Get the area clean before opening anything up. A tip about return line kits.Some a much better than others and we have two different sizes. The green clamps will be the small size. The red clamps are the large size and... They have the lines offset compared to the smaller size caps with the green clamps.
