Looks good man! I'm very happy with mine. Been driving it a lot and have filled up 4-5 times now and I can pull the gas nozzle all the way for fast fill. No issues. And I used 1.5" fuel line with 3/8" filler vent I think.
Another note, I love your charcoal canister idea. I don't smell gas from mine and it's always in the garage, but that's cheap insurance right there.
