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.


what gauge do you use to log psi by converting it to volts? i have a LM-1 and a LC-1?
i use a camera to look at on the gauge incase i dont look at them.
