Gas Tank Vent Manifold

Not that I'm aware of.

That looks just like the one on my 73 Satellite.

Inside the outlet nipple is a brass shuttle valve that is supposed to allow gases out and prevent liquids in.

Mine stuck causing pressure to build up during driving which could literally blow the gas cap out of my hand when removing it for fueling.

I had to cut a hole in the body, carefully drill out the brass shuttle, and weld it back up.

Plan B was to build a replacement manifold from brass fittings, but as the price of those fittings has skyrocketed in the past 3 years it would have been over $60.
