Doug, my rig does not have a prefilter prior to the Davco 382.

Forest, my strategy is to run this tank pretty low, and keep changing filters if needed. If it persists after the next fill up, then polishing will be in order. Hmmmmmm, 12V transfer pump from HF, ten feet of fuel line, and a water filter housing and filters from Lowe’s, the rusty gears are slowly turning...............
