Vapor lock

Has anyone had trouble with a STOCK predator doing this. I thought about drilling a small vent hole in the gas cap, like the old happy cap for a flat head.

Yeah. We've had it happen. Drill holes on from bottom side of cap. You'll see the chrome tabs that are out past the seal. We drill a 1/8 in hole in each one. And where the chain attaches to cap. Go through the big hole and drill another 1/8 in hole the vent plate. Just be carefule here and don't go all the way through the cap. CRE Motorsports
