accelerator pump rubber

Does anybody make rubber for the accelerator pump that will work with 10% fuel ? I overhauled my carbs about 5 years ago and both carb accelerator rubbers were cracked and had shrunk . I have ethanol free available and will start using it .

Several Vair vendors now sell Viton accelerator cups. Viton is highly rated for resistance to hydrocarbons and no reports so far from users here that they have any issues.

Try John Sweet on eBay or Corvair 1 or CA Corvairs or Clarks.

Hopefully the Viton cups will perform better, but keep in mind the quality of the original buna compound or Viton compound affects durability and sadly some of the aftermarket parts are not as good as OEM.

Let's hope the Viton works better and folks will report on them and were they got them from.
