check valve, do I need one

zemun2 · 10-10-2006

I was wondering if I need to use check valve, and if yes where would it be installed, before or after the pump? Nozzle mounted pre TB.
Running stage II kit with MAP sensor pushing aprox 20-21 psi on 1.8T

Thanks

After the pump, And no it's not required if the tank is lower than the nozzle.
