Anyone have a factory 402 non-A/C set-up? Would like to put a rumor to rest.

[71CHEVYSHORTBED402]

There's a long-standing rumor the 402 with A/C had a fuel pump with a return line to the fuel tank. I know it's not true, not for a 1971 anyway, because they only offered one fuel pump for a 71 402 and A/C doesn't matter. The fuel sender has only one line as well. A return line applies to 1972 only.

Even the part houses are on-board with the confusion. I know because of the pump to carb. lines they offer.

I don't suspect a return line has anything to do with A/C. So my question is, does anyone have a 1972 factory 402 set-up, non-A/C, and does the fuel pump have a return line between the fuel pump and fuel tank?
