I’d like to know the size of both lines… I’m replacing mine with rubber (front to back).

yeah my return line has a leak in one spot on the bottom of the car, i’m planning on just taking a length of fuel line, putting a slit in it then sliding it around the hard line with a couple hose clamps. i’m a lazy sob and don’t want to change the return line.

i just realized i have the hose on my parts car that goes from the return line to the fuel rail, i’m just going to use that since it will be the right size.
