    Default Fuel polishing

    I did a search and didn't come up with anything to conclusive on the subject. I use my own fuel around my place in diesel engines to go through it within a year. I put Biobor and something for lubrication in it when I get it. I do have several gen sets that I have installed that have one or two 55 gallon barrels of fuel onsite for strictly gen set use. It was dosed when pumped, but some of that fuel is two years old now.

    I do use a filter to catch moisture in the smaller bung of the drums when I set up the aux fuel system. That should stop any airborne moisture from getting into the tanks. But any moisture in the fuel already could start to cause a problem long term. What are people doing to polish the fuel to filter out anything? I know we have some pretty smart people in here so I'm sure someone has come up with a system that will work without spending huge bucks.

    The other alternative is to hire a fuel polishing company to come out and work the fuel over a couple times a year. I hate to recommend that as I'd rather do it as part of my regular service work on these gen sets.

    This is what I have considered. Let me know your thoughts on this

    Looks like Racor makes 2 micron filters for that rig, too.

    I plan on storing several hundred gallons of diesel at my farm, was thinking about one of these units too, if not just hooking up a pump to one of these: https://smile.amazon.com/iFJF-Separa...eparator&psc=1

    Or similar filter/separator with a 1 or 2 micron filter.

    Question I’ve got is how long and how often to run the filter to maximize any potential benefit.

    It’ll take a lot of research and review from where I’m sitting to find out how much of this kind of “polishing” is done prior to ever dumping it into a gas station’s underground storage tank and how much filtration occurs between that tank and my truck (or 55 gal drum or jerry can) making this process necessary, desirable, or superfluous.

    Thanks for posting.

    How much fuel do you plan on using for a $500+ filter to be cost effective?

    Id rather pour out fuel and buy new than to waste money on that setup. I can make you a filter set for less than 300.

    If it was just my own fuel it wouldn't be a problem. I'd be using the setup on about a dozen locations with anywhere from 50 to 100 gallons each. That's a lot of fuel to burn on a bonfire!

    What kind of filter setup are you talking about?

    Would a "Parker Racor 660R-RAC-01 660R10 Fuel Water Separator 10 Micron w/ Heater Option" from Ebay work? $30 with 30psi / 60 GPH rating. Pipe this filter / water separator up to a fuel pump and run your old fuel through it every other year?

    Still need some sort of portable pump that can move a decent amount of fuel.

    Define portable and decent. Also time frame/period.

    That was my question, too.

    How much is enough? How small a particle to remove (knowing a good 10 micron filter will capture smaller ones over time), how long to run and how often?

    Is this even necessary or overkill?

    edit:

    poked around the innerwebs. There's a plethora of information on this esp. among boaters.

    Good article here: https://theboatgalley.com/diy-fuel-polishing/

    YMMV.

    I was slinking around the net, too. This guy's operation looks good to me: http://www.alpharubicon.com/altenerg...ishercommo.htm

    I've only got 50 to 70 gallons to worry about so was thinking of filtering the tank during engine testing using one of my spare 803 fuel pumps. Slow, but inexpensive.
