I tried to use my new oil pump from blackstone today. Followed the directions ( I have a masters degree. LOLOL ) and when I test it on my finger I do get a little suction. Put it down the dipstick tube and can pump forever and get NOTHING... It is making it to the oil. . any ideas??? I still don't see how it even sucks oil out since the tube goes right into the bottle and into the sump... thanks!
