I ran steel 5/16 steel brake lines for fuel return. I bought a few 48" sections with some couplers and nuts then rented a double flare tool from Autozone.


Short rubber hose connects the return line to the tank return line nipple.




Splice at the mid body was the last connection made and the easiest to cut to length and flare in the last step.







This is the best I could do with the motor still in the car.


My FPR will be where the windshield washer reservoir used to be.



I'll pretty up these lines when the new motor goes in.
