Going from the oil pan to the fuel tank

After reading about oil changes on here last week I am going to build a system to pump my used oil directly to the fuel tank when I drain it. Has anyone done this. I searched the threads but did not find exactly what I want to do. I have a 1/2 hp gear pump (110v) that will pull from a 5 gallon bucket (1" line and fittings). The pump will discharge through 2 filters into the fuel tank. There will be no by-pass or relief valves, since I want to keep this simple. (KISS) I will post pictures when done and also pics of the mess should this all go south!!!

i am looking for info on this

I think you'd be better off letting it sit a bit in a seperate container to let some of the solids settle out first before filtering, then add it to your fuel tank. Just my .02.......

There is already a company making this sort of product.

It is called Oil Mate, by EMP
