Fuel return line 77 sbc into 69 with in cab tank

[andrewpclayton]

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.

X2 get a pump for a 70 and back or with just 2 ports,

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

Another option would be a 72 sender it has 3/8 and a 5/16 tubes
