Re: Clunk Line
Al, actually the Japanese carmakers were sticklers for fluorosilicone (Viton is fluorocarbon) and liked to use LCP (liquid crystal polymer) for pump inlets since while expensive, it was dimensionally extremely accurate and chemically resistant.
Not saying these are accurate today, but they were in 1990:
Ford - get it done right
GM - get it done on time
Chrysler - get it done cheap - hence the Buna-N. Stupid decision, parts failed within 6 months.
