Vented gas cap So I bought a new gas cap a while back and it was supposed to be a vented cap. However I’ve been noticing that when the truck is sitting outside it builds up pressure in the tank. And it also builds while driving as I have an electric fuel pump. Shouldn’t a vented gas cap prevent this? Reply Like 10 Sec. The Crown Automotive Locking Vented Fuel Cap is a direct replacement for the late export CJ’s. This fuel cap is keyed by the manufacturer and supplied with two keys. To maintain the proper fuel flow to the carburetor the seal and vent create the required back pressure.
