I think your information on the gas trash pump is a little skewed. Iíve been using one for about a year now and I believe if you have a sizeable amount of oil to collect itís the fastest and neatest way to go.
First almost all trash pumpís are self priming, I havenít had to prime my pump since the first initial prime. I have pumped oil when the temperatures were in the single digits. (I do use a heating element attached to an extension cord in the winter to make it go faster) but I have pumped some thick paste. Also you donít have to worry about the pump clogging it pumps the crispyís and all.
Second you can get a good gas pump for less than $200.00, I paid $180.00 for mine at Tractor Supply. You will pay at least that for a good vacuum pump, and then you will still have to manufacture the tank set up.
Third it is very neat. I have fittings in the ends of both hoses, so all I have to do is back in drop the tail gate put the suction hose in the 55gal drum I provided. Put the push hose in the barrel in my truck and start the pump. (And it is fairly quiet) My pump will pump at idle so itís easy to control the flow rate. Then when Iím done all I have to do is wipe the oil off the hose with a rag or paper towel put the cap on the fitting in the end of the hoseís so no oil dripís out and close the tailgate and away I go. No fuss no mess.
Sorry for the late reply. I'm in western Pa. The pump's brand name is Champion, I'm not sure of the GPM on it but I have it bushed down to 1" hose for easier handling. I'm out of town on business for a week when I get back I'll try to get a photo for you.

The SS looks easy enough from the picture. Can you provide any more details on the 12 volt vacuum pump (brand, where available, size, etc.) and the 'plumbing' portion of the assembly? How long does it take to draw vacuum on a 10, 20, 40 gallon tank? THANKS.
I may have to try that. I also have a very small 2 stroke generator, but it's noisey. I sure would like see some plans on the 'plumbing' part of the tank other than just the photo. Can you direct me where to look for them? Thanks again.
