Bad rear pump results in build up of excess fuel and fat condition.

Wire each pump on separate manual circuit with 25AMP fuses and proper quality toggle switches.

I recently put my fuel pumps on a separate fuse panel. Each pump has a fuse. ...

How can I test the pressure of each pump separately?

Should both be 106 psi?
