Pretty neat refining rig, nice design, the spin speed seems to be a bit slow, our Navy purifiers spun at about 60,000 RPMs if I remember right, but they were 440Volt an much higher capacity than the home brew rig. No doubt this rig gets the job done well for the home brew fuels fan..
Two things here, maybe help someone,, I don't remember the source or brand name but there are litmus paper strips that can detect water in fuels. also GM has sensors for water in fuel, as far back as the early 80s, should be listed under AC Delco sensors+water, maybe Google that, if interested.
I may install one later, maybe when I do the timing chain, water pump an valve adjust late this year, maybe early next year. Also maybe a truck size fuel filter with clear bowl, an drain valve too, could not hurt, injectors an pumps are very expensive, an I do not like being broke down on the side of the road.
Preventative measures are generally good investment in time an money. I remember the drain valves an settlement area we built on our locomotives at ARMCO Steel, saved us time an hassle cutting the 650 gallon steel tanks open with a small cutting torch, an risking a flash fire too. Cleaning them out that way was a hassle.
BTW, those fuel tank screens on the MB, can be cleaned real well with a can of spray Carb / Injector cleaner, have done that every two years, never had to buy a new screen.. 46 mm socket about $20, at discount parts.
Also, I jack up the rear of he car, put it high on jack stands to do this screen cleaning, an use a suction hand pump to take a sample of the fuel from the low part of the tank, an check for water there.
Never let it sit overnight with less than 1/3 of a tank of fuel, avoiding water from the tank condensation. That an a small bottle of Lucas fuel treatment, frm Wal-mart an I have minimum problems, did have it slow down one night, changed the primary filter an it went back to running like new. That was from fuel at a Valero Station, do not do that again. Dirty fuel for sure, stay with Conoco, an Chevron.
