Where can I get a vented gas cap

Anybody know where I can get a vented gas cap for my 84 K10? I am doing a emissions delete.

Re: Where can I get a vented gas cap

Has anybody heard of just drilling a tiny hole in the gas cap so it can vent? And just not overfill the tanks.

If you're deleting the canister, extend the vent line up to the vent on the carb that also connected to the canister and be done with it.

Re: Where can I get a vented gas cap

When I deleted my canister, I just put a metal fuel filter on th eline to keep dirt out of it and vented it under my driver's side fender. It has been that way for years.

Snowmobiles run something very similar to this.
