Does anyone know where I can get some from? I have a leaky fuel injection union on my tintop that requires fixing.

Rubber o-rings are readily available, but I assume that 'normal' rubber would be corroded by petrol?

Nitrile rubber is fuel resistant, if that helps you at all

For unleaded fuel you need viton O rings, send me a U2U if you know what sizes you need, may be able to help.

Ok thanks guys. Dingz, I'll measure up and send you a U2U.
