It's over there, on the left - I see it.

Seriously, one of these days, I need to do that to my hardware cabinet. Forty years of my accumulation, and I can't find shit.

Here is page two of the thread. One has replaced his with a GM unit, others have rebuilt the factory canister, but it seems to be a common issue. I started having excess fuel tank pressure last year on our road trip to Wyoming. Across the Nevada desert, with a ambient temperature greater than 94 degrees, below 1/2 tank, we started getting fuel vapor smell in the cab. Bleed off from the canister in the engine compartment, and then I'd stop for fuel and unscrew the gas cap, it would vent off the pressure for up to 20 seconds.
