   I installed F-391-18 (1/8" NPT) flush fuel drain valves (p. 153 of ACS
catalog) about four years ago. I recently noticed fuel weeping from one. As
I suspected, the O-ring was split. 
  Can anyone tell me what size replacement I need and where I can purchase
(in particular, a newer, more fuel resistant silicon-type)?
Also, what lubricant should I use on the new O-ring?
