sentra Posted September 3, 2014 Share Posted September 3, 2014 Does anyone know why the aeroflow catalog specifically says not to use their 30 micron filter with ethanol or alcohol? They say you need to use the 150 micron element. They are both made from the same material otherwise, the little bronze thumbcap things. -DJ Quote Link to comment Share on other sites More sharing options...
peteretep Posted September 3, 2014 Share Posted September 3, 2014 only fancy business people finish things off with initials I have an aeroflow fuel filter sitting here -PT Quote Link to comment Share on other sites More sharing options...
sentra Posted September 3, 2014 Author Share Posted September 3, 2014 Likewise The young guy behind the counter started going on about it, I told him it would be fine and brought it regardless, however my curiousity was aroused. Other forums suggest down to 10 micron at the rail is fine for e85 (I cant see why it matters what fuel), and these was a little hint that may shed some light on it, is "Dont run finer than 75 if your running it prepump" -DJ Quote Link to comment Share on other sites More sharing options...
danger Posted September 3, 2014 Share Posted September 3, 2014 Well you see David, In early test trials, ethanol was put into older vehicles with fuel systems that had become varnished during normal use with gasoline. Varnish generally only accumulates in fuel systems or containers which see little or no use. Ethanol removes this varnish from the tanks, fuel lines, and carburetors which is then captured by the fuel filter. Once the fuel system was clean and the filter replaced, this issue was resolved. Today’s gasolines contain detergents which help keep fuel systems cleaner and, in most cases, when ethanol fuel is added to a clean fuel system, there is little (if any) varnish in the fuel system and filters are less likely to become clogged.

sentra Posted September 3, 2014 Author Share Posted September 3, 2014 fixing the filter clogging by increasing the hole diameter seems like something americans might think appropriate? -HIV 1 Quote Link to comment Share on other sites More sharing options...
sentra Posted September 3, 2014 Author Share Posted September 3, 2014 Interestingly enough, the aeroflow one for alcohol/methanol is the same material, same surface area, just bigger holes. Quote Link to comment Share on other sites More sharing options...
ajg193 Posted September 3, 2014 Share Posted September 3, 2014 Maybe there is some sort of risk of water coming out of solution and adhering to the surface of the filter and corroding it when the holes are the correct size? Kind of like a catalytic converter EDIT: I see Dane must have read this: http://www.hastingsfilter.com/Literature/TSB/07-3.pdf Quote Link to comment Share on other sites More sharing options...
