  • Great product!
Size: 3/8 Swivel+ 8mm+10mm Adapter
This oil pump worked perfectly for changing the differential and transfer case oils! I would definitely recommend this if you want to start doing your own service on your vehicles.

  • Exactly What I Needed for Yamaha F200 XB Lower Unit Oil Change!
Size: 10mm Swivel+8mm Adapter
Worked perfectly on my Yamaha F200 XB for replacing the lower unit oil. Made the job extremely easy!

  • Great little pump
Size: 3/8 Swivel+ 8mm+10mm Adapter
Worked great on a 80’s Mercury BlackMax 150. One thing to know is to use slow pumps. Don’t think you’re going to fill the lower unit in 30 seconds. The pump will cavitate if you try to go too fast.

  • Works once the broken hose was replaced.
Size: 3/8 Swivel+ 8mm+10mm Adapter
Was disappointed when I tried to use it. About have way through the bottle of oil, I notice oil was running out. Found a split in the house. Had to put drain plugs in to stop oil leak. Cut the hose in half so I had just enough to finish the job. Will need to replace the hose before next service. Other than the hose, the product worked as expected. 2013 F70 Yamaha. ... show more
