    Install fuel pressure gauge

    I am installin a fuel pressure gauge on my gp1200r. Where is the best place to T into the fuel line? ( between carbs 1&2 or 2&3 or on the return line)

    thanks for the help

    Are you running a return line restrictor?

    No line restrictor. Do i need one? What do i need to get it to work?

    I install it on the main line between the 1&2 carbs. when and ran it, looks like I need to purge the line. got air in it. Was not readin anything.

    the return will allow you to adjust and or build pressure with the jet, should be @ 5-6 psi, the gauge will go after the restrictor jet.

    If the guage goes after the restrictor, how are you going to get fuel pressure readings?

    Dont worry, i had my primer T in before the restrictor a while back and was wondering why my primer switch was leaking... i caught it at the water when i ran it for 5 minutes, the primer will only hold 3-4 psi max, i tested it when i got home. It was fixed right away, talk about a blank moment, ive done alot of them but still seemed to screw mine up.

    You can not run a fuel pressure gauge unless you have drilled the returns in the carbs and run the restrictor like stated. Fuel pressure in stock carbs is created with the tiny outlet hole in the body, you would need to monitor inside the fuel pump to get pressure readings in each carb.
