Technical One way fuel valve

I have this fuel cell in the trunk of my 1930 Model A. I hopping someone can tell me what I need for a one way valve set up.

I think I need a one way valve on one side with a hose coming off it to vent outside the car and maybe even a fuel filter at the end. And I can cap the other one. One side has a vent on it, but I don’t think it’s the correct type of vent.

Both are male 10AN fittings

Thanks!

 

That looks like what we called "rollover" valves. They were also vents. Our organization quit allowing them unless they could stop fuel from coming out no matter what the position of the tank. My son and I both use a line from the top corner to the opposite side and at the bottom with filters on them. With todays fuel there is a lot more evaporation. Also we both use a -6 line even tho I feed my pump with a -10 and he uses a -8.

 

Given that the filler neck is in the trunk, down here it's mandatory for that area to be fully sealed from the p***enger compartment with a non vented cap being used. The tank needs to be vented externally with an appropriate rollover loop so any discharge is outside the car and not into the trunk or p***enger compartment. Safety first.
The vent tube needs to run up and above the tank and filler neck (If applicable) in a loop before it exists the body.
In my 35 Chebby I ran the vent from the underfloor tank up through the floor to the belt line where it did a loop before it it then turned back going down and exiting through the floor area rear near the ch***is, tank and fender. I'd recommend using an in-line one-way rollover valve connecting a vent line to it and use that marine fitting where line exits floor. That way no fumes can enter the p***enger compartment as tank vents externally.
On my 46 Olds I'm using one of that marine vent as a bulkhead fitting as it has also has a mesh filter screen that keeps out debris, plus it's compact and non too intrusive.for aesthetics as well as running an additional vapour return line to the filler neck. Additionally my return line connects directly to drop in-tank fuel pump ***embly.
