Fuel leal down test? 1991 240sx

I lose about 20 psi in 30 seconds. Is this oK? If I pinch fuel line between fuel filter and gauge, I dont lose the pressure so I know the check valve or canister or gas tank is leaking. Not sure if this abnormal.



I would say that is bad. It should be much less like 5psi for 2 minutes. Sparky
