gas filler check valve
ok so i just bought a 2004 truck, and a few days later it threw a code, soi went and had it checked at autozone, and its P0446, the EVAC system, i noticed when i filled up my tank that theres no check valve in the filler. is there supposed to be one? could this cause the code? i took a picture of what i mean..
