fuel rail

[waves]

I had my 04 optimax 150 2-stroke over rev. as I backed off on throttle. Found the cap at the top of fuel rail was squirting gas. Tighten it back down but motor would not idle. I see there is a shrader valve at the bottom of the rail. What is this for. All so will pumping up the bulb solve pressure problem.

One Schrader valve is for testing fuel pressure and the other is for air pressure 90psi fuel and 80 psi air. If you have fuel in your air side you may need a new tracker valve.
