Review on 🔁 Enhanced Powerbuilt 648759 Swivel Coupler with 360° Rotation by Jon Smith

I bought this to refuel my 2007 Honda Civic EX (5MT) during a fluid change. This worked for me twice, but it's quirky to use, leaks through the tube and leaks a little inside. Next time I will invest in a hand pump and hope for more success. For my taste, this one is a little bulky and dirty, and MTF doesn't taste or smell at all! (I speak from experience)
