dose anyone know were to get the #3 o-ring (the small one in the on/off valve). picked some up from mcmaster-car (no good) thanks Steve
Have you tried Home Depot or Lowes? It is surprising what they have sometimes. I needed some o-rings for another project and found out that they had a large selection of sizes. Another source may be automotive stores.
thay need to handel the cold temp. i can only find the black rubber ones at the stores. no good at cold temp.
