I trying to get my 1981 XS400 on the road and I just cleaned the tank and petcock. When I reattached it, gas leaked from where the petcock attaches to the tank. I assume that the o-ring needs to be replaced and I ordered a new one; however, I wondered if anyone uses any kind of sealant, silicone or oil on the o-ring to help with the seal.

Any and all help is appreciated.

Thanks,
