Suggestions on how to pull oil 12 feet vertical
I just installed a oil furnace in my garage. Oil tank sits outside about 12' lower then furnace and about 15' away. My buddy who helped me with this and does it for a living told me to run one oil line from bottom of tank to furnace. We tried to fire it the other night with no success. We used a vacuum pump to prime and once it was primed it would fire but then shortly go out and lose its prime.. so here's some details the furnace is older but was removed working. Oil line is new and air tight.oil filter is at furnace not on tank( new). From what I read I might need a tiger loop? Or a supply and return oil line with a 2 stage pump? Any and all suggestions are greatly appreciated
