Hi,

I have a Marina Pro oil changer in which I work my *** off with. Marina Pro states 45 to 50 pumps to extract the oil. This is true, but I have to repeat that step at least 8 times to extract all the oil. This accounts for approx. 400 strokes. I'm about to have a stroke. Yes, the oil is warm and the drain hose is inserted properly all the way to the bottom of the oil pan.

Ok, I'm all done crying. I have the Volvo Penta 5.7 GXI DP which has a garden type hose male fitting on the top of the dip stick tube. The pump mentioned above only uses a hose (without) using a garden type hose fitting.
I'm looking for a good pump that will adapt to the garden type hose fitting on my dip stick tube. Does anyone have any good suggestions for this type of pump? I may try to adapt a female type fitting onto my hose, therefore eliminating any possibility of suction loss through the dip stick tube. It's hard to believe that I am losing suction due to the hose being immersed in the oil.

Your help and suggestions would be most appreciated. Thank you, Ray
