i have a fuel pressure guage mounted on my cowl. easy to see if i've forgotten to turn the pump on when the guage is in your face. i also have one channel of the logger recording the pressure. normally after the brake is released the pressure drops from 9psi to 7psi. when it dropped to 5 we found the filter was becoming blocked from dirty fuel. if you can't afford a logger at least put a guage on the cowl in your face. it gives you something to look at if your engine starts to misfire at speed. helps eliminate potential causes.
