Fuel return line 77 sbc into 69 with in cab tank
I am putting a 77 350 engine into a 69 with the stock in cab fuel tank
The fuel pump on the 77 engine has the fuel line in and a return line. What’s the best way for me to make this work new fuel pump with no return? make a return line into the stock tank? Thanks in advance

If you do not want to install a return line, replace the pump.
I believe the return was to help prevent vapor lock. |

X3. If you have no vapor lock issues, just use a '70 style pump.
