Who sells a cap that is vented ? My car has stalled twice since gassing up . It is the cap because it runs fine with loose cap and I can hear wooosh when I release the bad cap

Snyders, their cap has 2 rivets instead of one. keeps the gasket in place and not covering the vent hole.

To be honest, I would prefer a non vented cap and a pipe leading from the top of the tank to somewhere under the car or to the inlet to the carburetor or some other location. With the windshield open I get the gas fumes from the vented cap coming into the inside of the car. On my Model T I had a small diameter copper pipe leading from the top of the gas tank to the exhaust pipe before the muffler. It added a little pressure to the tank so that I could go up steep hills. Plus, the exhaust gas, being free of most oxygen, was safer than having air in the gas tank. There was a coil of the small diameter copper tubing so that any exhaust gas was cooled before it got into the gas tank. The gas cap was sealed and had an O ring gasket.

Why not clean your existing cap?

I not only cleaned the vent holes in my gas cap but added an additional one. Be careful not to drill into the bottom of the pretty chrome part. Chap

I tried drilling but it still did not vent properly
I ordered from Snyder this a.m.
