1985 FJ100 Fuel Tank Vent Question

[ProStreetZ28]

OK, I did a search and found a ton of information on the later fuel cap with the two little flapper vents, my FJ has the chrome gas cap, this is not a California fuel tank. My question is where and how does the tank vent. I took the cap apart and it didn't have any flappers in it. I just used KREEM to seal the inside of the tank and I want to make sure that it didn't plug any vent within the tank itself. Thanks

I've got one of those caps apart on my desk now....

If you look at the underside of the cap, the tank vents through those two holes in the alloy cap that retains the locking mechanism and there are two one way valves in the upper body of the cap above that through which pressure is transferred either one way or the other.

In other words it vents from under the lid of the cap - there is no "piped to another place" vent as such like on the later tanks...

Thanks, I wanted to make sure I didnt plug anything up when I sealed the tank. Now if I could find a new seal for the gas cap.
