Pumps are not as easy to find cheap for any of the 6.5s. The full mechancial pump for 6.5s - turbo or non-turbo, was only made for one or two years for Civilian use (up to 1993). Many more were - and still are made for the military.
Any pump model number ending in 29 - is a 6.2 pump with .29" pump plungers, whereas any pump model number ending with 31 is a 6.5 pump with .31" diam. pump plungers.
With civilian models, the DB2 pump was only used up to 1993. After that, the electronic-controlled DS4 was used. Some DS4 pumps use a pump-driver that will not allow use of all fuels.
I only used waste oil products in my GM 6.2s, Isuzu 2.2s, and my Ford IH 6.9s and 7.3s.
In regard to prices - I often buy entire engines with pumps on them, in the $50 price range. I've got over a dozen spare injection pumps sitting on my shelf.
About filtering - all my waste vegetable oil gets poured through a cheese-cloth, then dumped into my bulk fuel tank. My waste engine oil gets no pre-treatment at all, just goes directly into my bulk tank. My bulk fuel tank is 600 gallons and has a fuel pump with its own fuel filter on it. I've had zero problems, but the content of waste-oils to the diesel is never more than 20%. And, one warning. Just a few gallons of waste motor oil turns the entire 600 gallons a dark color. Not sure what questions would come up if my fuel tank was ever "dipped" and the dark color noticed.
Here are a few DB2 pump numbers for 6.5s.
