Fuel Tank

[gus]

I am looking at making my tank, and using the sender unit from the donor. I would use the feed and return take offs that are part of this assembly.

What I was wondering was what people have done for venting the tank. Is it part of the filler neck assembly, or could I use the one way valve from the brake servo pipe to let air into the tank, but not let fuel out?

Any advice appreciated.
