10mm Non-Return One Way 3/8" Air Fuel Oil Check Valve Diesel Gas

I have a muscle car that when it sits for a week of so the gas runs back to the tank and its hard starting after that.I put the check valve in the fuel line as it came out of the tank and that solved the problem. It works as it was designed to and it was inexpensive.

Good price

Part ok

using this for a check valve in my oil catch can setup.

Better that slice bread
