Bought an electric oil pump to draw the used oil from my engine. The kit included a hose that has a female garden hose fitting, which would screw over the OMC 4.3's threads at the top of the dipstick tube. Great - that would eliminate having to use the long probe drain hose.<br /><br />But, the pump's garden hose fitting is too big for the dipstick's threads, and just slides over them.<br /><br />What gives here? Do I have to buy some type of pipe adapter to get a pump hose to fit the OMC's dipstick threads?
