Pelle,
For auto gas and methanol, you need to stay with Buna-N {Nitrile}, which is probably what was in there to begin with. It's a good idea to change out if you can because most rubbers have a sheilf life of 5 years. Buna-N, or Nitrile, also goes by the following trade names: Chemigum, Hycar, Krynac, Nysyn, Paracril and Perbunan.
