I also hooked up the fuel feed line, using the original carbed line...which is nylon, just like the efi cars. The chassis harness/fusebox also had the fuel pump wiring already in it, so I only need to run 12v to the harness at the wire going to the in-tank pump, and it runs fine. I tested it...and dumped a bunch of gas on the garage floor, lol. Still pretty happy though .
You had nylon feed line to the carb??
I'm still thinking about replacing the nylon feedline on the B230F with the original carb steel feed line. Which is exactly the same steel line as the return line on the B230F
