You've not had any mold or other growth in it in 5 years? I can't get past 4 months here. But I've not tried the above yet. I've a couple gallons of an orange 50-50 mix, what the diff between green and yellow/ orange? I went out and found a gallon of prestones 300k miles pure stuff, pale green but quite clear, I could see all the way to the bottom of the jug. Came back in and found a tea strainer, took it and a disposable plastic box out and scooped up as much snot as the strainer could catch, put half a gallon of the Preston in it, and jerked the hose off the pump. Started the motor at about 8g's and put the air hose into the line I'd pulled off the pump. Got huge gobs of slime out of the motors return line splattering back into the tank, and kept blowing until nothing but air came back out. Clean up the floaters with the tea strainer again. Added another quart of the good stuff, shut the motor down and waited for the timeout to shut the pump off, several minutes. Stuck an arm into the tank and hooked the high side hose back up to the pump, washed me up. Got a small lead pencil flow out of the return when I started the motor. greenish liquid is cloudy with visible particles moving around. Rigged the tea strainer so it caught the return flow, and left it running to wash me up better. Now what I need is a paper fuel filter but about 10x bigger and no metal to rust. Put it on the pumps outlet so the crap doesn't have a chance to get back to the motor. Large car fuel filter maybe? Something with a paper element, but no iron to rust. All plastic and paper. Looked around on the net, no such luck. Household water filters could be used but they are all so over designed for city pressures even the junk starts at $40. Come driving weather, go look around & see whats under 5 years of dust on the shelves. You have any better ideas? I'm about what if'd out. Thanks Todd. Take care & stay well. > Todd Zuercher > P.
