[SEL] Fuel pump check balls

[Curt]

Tom,
While there are certainly many SS bearings made for the food processing 
industry, I believe you'll find the vast majority of bearings are made 
of 52100 steel. That's 1% carbon steel and the only stuff that will let 
you get super hard Rc numbers. Typically around 50+ for bearings.
The higher the hardness the better the fatigue life.
