My prefilter would turn BLACK after less than a half-tank, so I took action.

I drained the tank, when I removed the hose from the bottom of the tank, the fuel GUSHED out, so the in-tank strainer is not clogged (or it has been compromised in some fashion) anyway, I filtered all of the fuel, and got lots of black gunk out.

I now have 2 primary filters in the fuel line, and I have been reusing the prefilters. I can't believe all the gunk that comes out of that tiny filter.

Am I the only one here cheap enough re use the primary filters?? I just rinse with simple green, gently blow it out and reinstall. (then 100 miles later its jet black again.)

I'm using a star-brite fungus enzyme, (the same one I use in my boat diesel) hopefully its doing its job.

Cheers,
Robert
