Need opinions on how I primed my oil pump on 8ba flathead. I bought one of those suction oil/ fluid pumps ,the one that you can stick hose end into a can of oil and pull the handle and fill the pump.I then made a fitting to connect the pump I bought to the oil line coming up from the back of block ( goes to oil sender and oil filter canister) and pumped 1.5 quarts with steady pressure. I have not added oil to filter housing or oil pan. I will need to add 3.5 quarts total ( 1 quart to oilfilter canister , 2.5 quarts to oilpan( crankcase) . Is 1.5 quarts enough for the priming? I plan on spinning engine some with spark plugs out before I actually fire it . thanks for replys.
