Stock Fuel Filler with new Boyds tank questions

[Blazerowner]

I went through AZ performance to get mine. They are a vendor here. I've mocked mine up and it fits well. I never thought about the vent sizing, but I think I would just do a line and filter and not worry about the stock line. One thing to be aware of is the original tube would go in front of the body mount. Their tanks neck goes behind the body mount. So if your filler is still all there you may have to cut it. Mine was already cut so its just a matter of running a new hose.
