OMC Portable Gas Tank Venting

[TN-25]

I have an early 60's non-pressurized single line 5 imperial (6 U.S.) gallon tank. Recently while transporting it with fuel inside it just seeped fuel out the whole time. I did not have the hose on it at the time. Fumes were so strong that I will not use this tank until the issue is resolved. It has the correct cap.

Is is possible that dirt or debris could have messed with a check valve on the coupler? Do I repair or replace parts? Can I dissassemble and blow out the coupler?

Thanks!

I have seen similar topics posted here but not this particular one.

the gasket in the cap is probably shot. do know of replacement. discard and buy a new tank. the plastics work fine. just get OEM connectors.
