hi guys i started smelling a strong gas smell around my bike then noticed there is a leak coming from the petcock where it screws into the tank it seems to just be a seal problem was wondering if gasket sealer or something could fix it ? but also want to be able to remove the petcock if needed so i dont want it glue petcock threads to the tank there seems to be enough room for an o ring but im not sure if i can find one gas proof
