Monitoring fuel pressure during run - 04/13/10 07:21 AM

Do you guys have a way to monitor your fuel pressure during a run? or do you just run the guage by the carb and call it good? if you do, whats your setup? where do you put your guage? Im semi looking for a kit or what you used to piece your setup together. thanks!

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.

guage is mechanical & logger is a sensor in the fuel line by the carb.

I have the gauge mounted in front of me inside the car. It uses an isolator with the fuel going to it and then antifreeze from the isolator to the gauge.

You use a pressure transducer... most are set up for
a 1-5 volt span

Is that sensor available in NZ?

After the issues I've had I'd like to log the fuel pressure on my LM2

like most here all the gauges are in my face...
