re post #84.
The fuel pressure is vacuum controlled. One way to check pump pressure is to clamp off the fuel return line, but only long enough to read the pressure, which is probably close to twice the operating pressure (engine not running or you will flood it). Check it with the battery fully charged and when the battery voltage is lowest.
As long as the pump pressure exceeds the 40 psi max operating pressure, you should be fine.
Oh yes, fabulous build.
