Hi Randy Water in suspension is not the same as water held in an emulsion. Eg:
"Water Content - If emulgated [emulsified], a higher water content is not disadvantageous (as long the emulgation remains stable, which is very difficult). Normally water will cause problems anywhere in the fuel system." -- Comments from Elsbett Technologie on the German PPO fuel standard: "Quality Standard for Rapeseed Oil as a Fuel" http://journeytoforever.org//biodiesel_svostd.html#vegstd There's quite a lot of discussion about this in the list archives.
