just installed a airdog2 165 on a 94 12v cummins, my question is, where does the return line coming from the pump go to? i know it comes with a fitting that hooks up the line from the injectors but, where does the other end hook to?

 

The return line on the air dog should go right to an elbow that is hose clamped into the filler neck. If this is what you mean?
