Webra Woes

[Brian Young]

I have had similar problems w/ hairs fibers and junk
in the pump. Pump is very sensitive to trash. I now
use the hanger 9 filter which has a very fine element
and a sintered clunk in my fuel jug, and my tank to I
think.

Some of the other screens/filters I used would let
fibers pass through, the Hanger 9 has a tapered cone
shaped element and I hope nothing sneeks past it.
