Features

  • Versatile Adapter Set: Comes with a 3/8" rotating metal adapter and both 8mm and 10mm metal adapters, making it compatible with most outboard motors, including Johnson, Mercury, Evinrude, Yamaha, and Honda (not compatible with Volvo Penta)
  • "Third Hand" Butterfly Adapter: The butterfly adapter acts like a third hand during pumping by securely anchoring the filler tube into the fill port, providing extra stability and convenience for hands-free operation
  • Two Rigid Suction Tubes: Includes two rigid tubes of different lengths (5.9" and 4.7") to easily reach the bottom of quart bottles of varying heights, ensuring minimal fluid waste and maximum efficiency
  • Fast & Efficient Pumping Delivers 8cc of fluid per stroke for quick refills of marine lower units. The 20" flexible silicone hose is long enough to reach tight, hard-to-access areas, making fluid changes simpler for boats and vehicles alike
  • Multi-Purpose Fluid Pump Ideal for siphoning and transferring a wide range of fluids including gear oil, transmission fluid, differential oil, and lubricants. Perfect for boats, cars, trucks, RVs, motorcycles, and more

  • Works perfectly, quality silicone tube
I used this to change the PTU fluid in a Ford Maverick. The hose is a nice quality silicone, and it pumps a good amount of fluid quickly. I saved tons of money by doing the fluid exhange myself and knowing it was done properly. The screw on lid is made for standard quart containers so it worked great on the Ford Motorcraft oil. ... show more

  • Small transfer pump
A little smaller than I thought, nice to have included extra accessories. This "transfer" pump worked well....pleased with the purchase & at a reasonable price too....

  • Must Have Tool
This is a must have tool for refilling differential and transfer cases. It's a little difficult to use if you don't have your 4x4 significantly raised off the ground.

  • Pump cracked during first use
Worked well for filling half the rear differential and then pump cracked. Can't send it back with oil in it.
