Gas cap

Can gas caps wear out?

Drove truck today and dash display reads "GasCap".

I removed it and re-installed it making sure it was tight.

Display still says "GasCap".

Yes, they can although I don't think it's that common. Could be the gasket on it has failed as well and not sealing the system.

Put some Vaseline on the gasket and see if tha solves the problem. Not all replacement caps will work either, so just replacing the cap doesn't always work.

Nathan I will tune that out of the truck sir it’s likely an Evap leak at one of the fittings on the tank we did since it had to be played with it’s a good bet a fitting is leaking now vapor not fuel.
