Outer Limits 4x4 Board

Hey
Just bought an NJ in very good cond, seems to build up pressure rather quick in fuel tank, doesn't matter if it quarter full or nearly full there is always a resonable amount of pressure when fuel cap is removed.
Is it hard to access the tank breathers or am i going to have to remove the tank to do this, Thanks in advance for any help.

The tank should be "breathing" through your carbon canister. Find the line from tank to canister and check that.
