ASAP - fuel filter, is blue - in or return?
 

On the inlet side of the fuel filter, there are 2 fuel lines, BLACK and BLUE.

I mixed them up
I read that the black is the return but just saw a photo where the blue is return??

The out side is easy, blue and vacuum.

THANKS!

Blue is the "RTN" (center connection)
Black is the "IN"

I pulled up the back seat and checked the lines at the pump, Black at the elec. pump and blue at syphon side.
Also found this photo:

Maybe this will help someone else that wasnt paying attention when pulling off the lines......

That’ll be me then. Thank you!
