Fuel pump 861155a3 is a boost pump, meaning it is installed between fuel filter and cool fuel pump. The pump was a add on pump to help stop vapor lock on motors. This pump does not produce the 43 psi your looking for

This is a VP issue. The over heat could be a plastic bag was caught on the drive, I don't know. I really like Formula over all I've ever owned, but they are much more cost then chap

Welcome
Don't know about another fuse but sometimes there is stay alive power direct from the Bat. If there is stay alive then there will also be a fuse on this wire close to the Bat
