MityvacMV6400 1 Gallon Fluid Dispensing System for Topping Off Fluid Reservoirs, Master Cylinders Includes 5 ft. Hose with Wand and Flow Control Valve

Great product . I returned the first one because of a problem , it was easy to return , and the refund was fast. I ordered another one and it literally came the next day after the one I returned. The Mityvac works fantastic and makes decanting automotive fluids , such as diff oil , and trans oil , like the newer 8-9 speeds , which are filled at the bottom @ the trans pan , effortless and so easy with the brass shut off valve , precise filling is very easy .

Works great for filling differentials and all types of gear cases. I did have a problem with air bubbles leaking into the oil stream. I contacted Lincoln (owners of Mityvac) via email and received an immediate response. I had a add some sealant between the pickup tube and the coupler in the top of the tank. Easy fix and no issues since.

I bought this pump to pressure bleed brakes along with the Power Probe Master Cylinder Adapter Kit. The only modification needed is to swap out the Mighty Vac connector at the end of the dispensing tube with a Universal or Automotive/Tru-Flate coupler. The Unit is well made and holds pressure. The pressure relief valve avoids unnecessary spills seen with other pressure tanks.

Works great. Very easy to use. I am a professional Tech and this product make my job earlier. Down side slightly slow to fill due to the tube size. But worth the money.

I care enough to put magnetic drain plugs in my transmissions and differentials. I change gear oil every 30,000 miles. Gearboxes last forever if you do that. I used to use a hand pump that screwed into the top of a one gallon gear oil jug and always wondered if the pumping was ever going to end. I am old enough now to get muscle spasms doing that. Trying to squeeze oil out of a hose connected to a one quart bottle of gear lube ends up with getting oil everywhere. You put the gear oil in this device, pump it up with air and then open a valve and watch the lube go into the gearbox. Close the valve when the gear box is full, put the cap on the fill tube and the only drips are in the catch pan under the gear box fill hole. Using a heat gun to put a short right angle bend on the end of the fill tube can be helpful. I wish I had bought this rig a long time ago! It is the only convenient way to fill a gear box from under a vehicle. Someone with a little plumbing skill will figure out how to pressurize the bottle by converting a spare lid with suitable parts, as I did, but make sure that you use 20PSI regulated air if you were to do that.
