My GTX keeps vapor locking after I turn it off (fuel boiling out). I'm currently running a Holley mechanical pump, Eddy RPM Performer and Holley 750 DP. I have used an electric fuel pump before (Carter super pumper) and it was soooo loud, so I don't like it.

Can I put a "cheap" electric fuel pump in line with the mechanical pump so when I turn it off and the fuel boils out I can just flip a switch and turn the electric on to get it started? Will the mech pump let the electric pump through it?
