I have been running filtered WVO in all but my '91 the past 2 years.(Grease and Diesel 50/50 in winter)
Most of my grease is dropped off to me in 6 gal cubes. I filter to 100 microns, heat it to 180 for an hour or so, filter to 1 micron and put it in the tank.

I have been trying to figure out the best way to collect grease at businesses in a 55 gal barrel. Bilge pump, 120 pump with generator, or hand crank it out into a barrel. THEN.....I saw my neighbor getting his septic tank serviced and it came to me.

Inverter for vac pump or wet vac to create a negative pressure in the barrel and a hose to the grease vat, that way no french fry gets stuck in the pump.......Anyone have any other ideas.
A more cheaper, primitive, grease sucker upper ?

A diaphram pump will move almost anything. They are used to pump concrete. You will need compressed air to run it.

Not sure how much diaphram pumps go for, but the OPs idea is probably cheaper and cleaner. I like it.

I use a modified small block chevy oil pump on a portable 20 volt drill. Fills a cube (4.6 gallons) in less than a minute. I have about 6 ft. of collection hose with a screened pickup. I can pump out of anything and it will pump oil that is quite thick. I can pump well over 20 gallons on a single 20v. lithium battery. I can usually pump all I collect at one stop with one battery. No vacuum pumps, no converters, no collection tanks. It goes straight into the cubes. All this fits in a 18 gal. tupperware tub I keep in the trunk.

netboy,

there is a technical term for this type of grease collector, a Super Sucker.

A more sophisticated design:

Be REALLY careful pulling a vacuum on a 55 gallon drum. They are not designed for it.

All big time grease collectors i know collect with sucker tanks usually made out of big surplus propane tanks. Sometimes big enough to be trailered.

Perhaps you can find a way to utilize the vacuum from your Mercedes to create a vacuum in your sucker container. Many moons ago when i was a youngster the trucks that did septic tank work used the vacuum from their engines to create the vacuum in their huge tanks,by the time they drove the truck to the location they had enough vacuum to do the job.

I use a 12v pump from Northern tool with some pvc hose and strainer on one end, and hose and filler nozzle on the other. I pull from the 55 gal drum I leave at the restaurant. I have it down to 15 minutes to get out 9 cubies, set them in a row, hook up to my marine battery, fill them up and put back in the Excursion or van. I rarely spill a drop. I am usually in my work clothes (slacks and pollo shirt). The equipment all fits in a tidy rubber maid bin. With the extra NT warranty I am covered for or 2 or 3 years, so it is well worth the investment considering I pick up $120 worth of fuel every couple weeks. I thought of doing the "sucker" but it would be too big, heavy (when full) and more time to mess with than necessary IMO.

I have often wondered if a an electric clutch-driven pump off the belt would work, given the proper plumbing, etc. Does anyone know if a spare old a/c compressor would do the trick?

Go to greasecar.com forums. It has all the information you need.

I have been using this setup for 4 years now. It uses a Sureflow 12V diaphragm pump. I have since modified the original setup to use camlock fittings. It sucks the oil in and pumps it out through the same hose using a set of 3 way ball valves. Cheers Dan http://biodieselpictures.com/viewtopic.php?t=249

Find an old compressor tank and a vac pump. you can also use the compressor off a fridge or an old ac unit to make the vac. use a pool hose to suck. I have seen a 55 gal drum sucked up in about a minute. This was my plan till I changed up my collection and now buy in bulk. I have a monster gear pump from Leon at WVO designs and can move 330 gal in about 12 minutes
