The picture is of a Racor
15gph filter after approximately 110 hours. The clear bowl had 1/4 inch of the same material in it with no water
. It's now been 6 months and 50 hour so I replaced the filter again. I found nothing on the filter this time but I'm still getting some on the bottom of the bowl. The engine
is a 1996 3gm30f if that makes a difference.
I have no access panel on the tank and the sending unit is in a ridiculous place to get to for a look. It was recommended I use a mantnance dose of Valvtect BioGuard to stop any new growth. The thinking is that my problem is minimal now and with regular filter changes and BioGuard in each fill up it shouldn't get any worse. But of course he's not the one coming through the inlet bridge with the tide ripping.
Does this sound reasonable to you?
Thanks in advance, Woody
