Having read this and other threads, I'm still confused. Want to replace the o rings in some leaky fuel line connectors. Probably also need to replace some valve o rings in the tanks. Can anybody provide a standard number for these? I don't want to pay several dollars for an o ring that should cost several cents.
The most common o ring sizing standard is AS568, the US Aerospace Size Standard for O-rings ( I think it used to be AN). I would think OMC would have designed around standard sizes. There is a chart of standards sizes here: http://www.applerubber.com/src/pdf/as56 ... -rings.pdf
Is it true that the tank valve o rings changed over time? Anybody know those sizes?
