Had a friend helping me change out fuel pump, he unhooked the fuel lines at pump without marking what went where. Now not remembering. Anyone sure where the return line goes? Pretty sure its the last but not sure. Thanks for any help here.

 

Sorry, thats s10 blazer, 4.3, 1991

 

Im pretty sure that on my 93 they all lined up on the sender in the same pattern as they do on the lines on the bottom of the truck. My return line was a little longer than the others too.

 

Hey, thanks alot. I would`ve hooked them up wrong without your help. Very much apreciated ohsofly!

 

you have 3 different size lines 3/8" is fuel feed 5/6" is return and 1/4" is vapor return, on your sender three tubes same sizes, pretty foolproof . just hook up corrosponding hose to the same size tubes
