Gas Cap Maintenance

Postby Midnightsun » September 25th, 2019, 7:03 am

Just a reminder as many never think about this. Your gas cap has an o-ring on it that seals the tank and keeps rain/wash water out of your tank. I highly suggest you remove it/them and replace with a new if you have never done so or if it looks to be in great shape then just apply silicone grease or o-ring lube to it. This will keep it looking and working great not to mention the gas cap comes on and goes off much better. A telltale sign it needs lube is slight squeaking when installing or removing.

That is a good one,....just to add......while you are doing the ring, take the time to check that the grounding is still good....another overlooked maintenance check.
The above is strictly my opinion always based on years of doing...remember to support local business , it pays back.

I replaced my o-rings a couple years ago. Pulled them out one time and saw a bunch of cracks. Only cost a couple bucks each and got them at the local hardware store. I don't use gasohol, but if I had to I would have upgraded to viton rings instead of the standard rubber ones.
