Hi, I am using an original 32 Ford tank. I added a roll over vent valve. Will it work to install a small fuel filter on the end of the vent? The hope is for the tank to breathe and keep dirt out. The stock vent was in the same location with no filter. The filter would sit on top of the tank. My engine is a mild 283. Highboy so no place to hide a vent under a fender.
I can't see a filter is going to create any issues. Although not what you've asked, I'd be routing the vent line accross the tank to one side, then up through the trunk floor, rising up some then looping down back through the floor to vent to air. This results in little chance of any fuel sloshing out of the vent, particularly when the tank is full. My roadster trunk often stinks of fuel, but my new coupe doesn't ever. My roadster is due some work! Chris
I looked at doing that, the Tank’s site tech states there should not be a loop so that gas does not get trapped and plug the vent?
Not a loop, just run vent upward, 180 degree bend, then downward through the floor, as suggested. Some use very small K&N type air or breather filter at the end of the hose. Something like this: https://tcbros.com/products/crankcase-breather-filter-with-mounting-tab-for-3-8-id-hose

That is the simple solution that works. The vent is decently above the top of the filler neck and vents to the air. Snagged photo below. A filter is a good idea simply because remember, the vent doesn't just let fumes out when the car is sitting in the hot sun, it's main purpose is to let air in to replace the gas the fuel pump pulls out of the tank and if air doesn't go in you create a vacuum in the tank.
