I have seen so much info about WVO pumps and short of Goulds pumps for thousands of dollars I have not seen much really practical for severe duty…12V pumps are ok but not continuous duty… I thought I might try something different… I got a large but very economical water pump with a gas motor and modified it for WVO…we tested it today and it will fill a tote in about 90 seconds.. It was awesome…the one thing to note is you want to ball valve the pump to avoid having to prime it…this keeps the pump body filled…use up to 2 inch hose even…ohhh and the cost…pump…hose…fittings…how about less than $300.00
