After pulling my rv a few hundred miles i noticed my driver side of the truck was covered in fuel. I've noticed it before and actually taken it in for that reason and was told nothing was wrong. Then I took it to another dealer and they said that a injector was lose, so I thought the problem fixed. Now here it is again. Anyone have a idea about what it could be?

 

I had my main line coming up to the rail get loose and leak once. I bought a new one thinking it had a hole and it was just loose.

 

If you find out its a line. Dont buy the line from the dealer. just go to a place that sell Hydrolic lines. They will have a rubber type hose that can handle the PSI and wont cost you a fortune to fix. The old 2 gens had issues with fuel lines rotting along the frame rails. They wanted like 400 for the lines. A couple feet of hose at 15 bucks a foot fixed all my issues.
