Via iPhone.
Thanks for the tip. I put some of the filtered material in Acetone and it did, in fact, dissolve. From this info and the visual I think Asphaltene is confirmed.

No access to the bottom of the tank, but I can drop a hose in and pump some fuel out to check that.

I have some Asphaltene chemicals coming tomorrow and my polisher/circulator is one fitting away from completion. I'll do a cleanse on Thursday.

On water, don't know. Remember those filters are 5 years and 300 hours old. The boat has never had a problem with fuel delivery. All new filter/separators were installed today. I think I'll have it all corrected shortly..

Asphaltene dissolved:
