[Double Venom]

More thoughts on venting: Ford uses a "roll over" valve for their tanks from the olate 90's. Small litle valve but should be big enough to handle the ventige.

A 3/4"(?) hole cut into the top of the tank, the valave then pushed in (Factory has an OEM rubber grommet fo it). Once installed a small hose is attached to it via the factory barbed end. This valve will not let fluid out but it will allow air to pass.

This idea should work ---? Might be a little difficult to install in a used-partially filled gas tank though!
