My truck was ideling yesterday and all of sudden is started surging and barely was running. I limped it home and it has fuel leak off the back of the fuel rail manifold. Is it more common to get a leak on the manifold or the line out the back of it toward the firewall?

 

Check your injector line tubes.

 

They looked ok. The line out the rear is that a return line. If so anywhere to get it beside the dealer

 

Weather was nice today got a better look at it. The number 6injector line was loose. Snugged it back up and back in business.
thanks

 

Glad to hear!
