Return Fuel Line?

Do the 69-72 blazers have a return fuel line? I can't remember.

The return line started in '71 or '72, I think. My '70 does not have one.

My 72 4x4 did have a return line. It is completely inadequate for fuel injection applications however.

The return line is only 1/4" The minimum recommended size you can use for a return line is 3/16" and 3/8" is preferred.
