I was thinking on this modification and I think it may work.
Chime in and share your thoughts.

Single line to the fuel pump NO return line. Talking mechanical pump.
Single line going to the carburetor from fuel pump.

Yea that is the typical setup.

Now I have seen those return type fuel filters.

What if you put a T in the line a few inches BEFORE the fuel pump.
Attached this small return to that T.

That vapor lock and boiling in my vehicles happens after the pump.

Would this get rid of the air in the system.

I think some of those filters were used and hooked to the mechanical pumps that had 3 fuel hose connections on them.

Correct me if I am wrong or way off base.
