Your cart is empty.Mityvac is a brand of automotive diagnostic and service repair tools since 1971. Beginning with the design and patent of a single hand-held vacuum pump intended for medical applications, its uses broadened to include automotive diagnostics and service as well as industrial and consumer applications. Mityvac fluid evacuators are ideal for removing fluids from small tanks and reservoirs. These units are lightweight and portable and include integrated reservoirs with capacities ranging from 1.9 qt. (1.8 l) to 2.3 gal. (8.8 l). Vacuum is created quickly and efficiently by manual pump operation, offering superior mobility by eliminating the need for electricity or compressed air. The MV7400 is ideal for draining fluids from reservoirs on boats, RVs, ATVs, snowmobiles, farm equipment or motorcycles. Includes accessories for draining engine oil or transmission fluid directly through the dipstick tubes. Mityvac offers the products and systems you need for any brake and clutch bleeding application, air induction cleaning and compression testing, cooling system evacuation or refill application, for fluid handling and diagnostic applications.

This product is what to expect from Mityvac 👍👍 I have used their products for years now and they stand up to the test of time.

This has by far been the best investment for servicing my equipment. Works great for doing small gas engine servicing and can easily extract engine oil or bad fuel without the mess of drain pans. We also use it for oil changes on our inboard boat engine. It literally took us 20 minutes for a job that used to take over an hour. I keep finding new things to use this for.

This is a good purchase. Built to last and works as advertised. 3 sizes of vacuum hose come with it. Place the best fitting hose into the dipstick port, pump the handle to create an internal vacuum, and it will take care of extracting the old oil. Ideal for boats where there is no way to drain oil from the engine block. I also use it for lawnmower and generator oil changes.

Recieved this Yesterday, but was busy and finally opened it today for an oil change on my car but to only find out this Float/shutt off device was completely broken off and free moving at the bottom, thinking the pump should still do it's job, but nope, inserted the Main Line in and pumped to no suction. Would love to get an exchange. Will edit for an update.

Works very well on my 4 cyl Mazdas. My V6 dodge bends the dipstick in a way that the smallest tube supplied would not go down into the pan.I was a little frustrated. I had some spare small-diameter clear tubing (like aquarium tube) in the garage, and I tried it. It went all the way down into the pan just fine. The other end fit into the Mityvac tube just fine, and the unit worked.

This works quite well for pumping hot or cold oil from a crankcase via the dipstick tube. Easy to use, powerful suction. It will empty 4 liters of cold oil in about 10 minutes. Needs to be pumped up twice. Hot oil in half that time. I use it for changing both outboard and car oil. No mess, easy access, easy to pour out. Pretty solidly made. I have owned three of these units for several years. They have stood the test in winter and summer, on the dock and the driveway. Will pump out a gas tank very quickly

Simple pump system thats works quite effieciently. Comes with 3 different diameter tubes, 2 of which are smaller diameter to fit dipsticks, and one large tube. The evacuator itself is about 3 1/2 feet tall give or take. Definitely of thick, heavy, dense, quality plastic, so breaking or wear on the evacuator is minimal. It is like a bike pump, you pump it up and down. There is a cylinder in the middle that is seperated by plastic from fluid. So there is no fluid cross contamination or worries about fluid getting into the pump, everything is sealed nicely. The handle is a nice sturdy size and the vertical piece connecting to the pump is about a 1/2 inch in diameter and doesnt feel like it is flimsy. I pumped quite violently and hard and it stood up without issue. There is a small U shaped kick stand that keeps the Mityvac balanced while pumping. The tubes come with seperate adapters that are each FOR THAT TUBE, MIXING TUBES AND TUBE ADAPTERS WILL RESULT IN POOR SUCTION. The adapter goes into the pour spout, which stays snugly with its two ridged seals.I used it 3 times so far, one for a TDi engine oil change, a Lincoln oil change, and a lawn mower oil change. Worked great for all three and got ALL the oil out.I definitely reccomend this if you do your own oil changes. Saves time, effort, and will last. Only thing that sucks is the price at $70, but I believe it can last for a very long time without problemsBiggest thing for me is I dont need to jack my car up to get to the oil pan, but for cars that have filters underneath and NEED to be jacked, It gets rid of having oil splash all over you and minimize cleaningTips-For oil, make sure the oil is warm or somewhat hot, but NOT AT FULL OPERATING TEMP. YOU WILL MELT THE TUBES. Wait until the temperature is about halfway between COLD and NORMAL OPERATING TEMPERATURE. The oil will be warm enough to come out smoothly.-Make sure the tube adapter is dry and not wet at all, it helps with the seal- Pour out fluid into a different container each time you do a fluid change, you dont want dirt and grime to sit in the Mityvac-Pump at a continuous rate, I find that a full pump every 2 seconds is good enough to keep a good flow going-Clean adapters and hoses after each use, fluid will get stuck and be a pain later on. Just pump the fluid out into the MItyvac until the line is clear. If the fluid is too thick. remove the tube, place it vertically so that the fluid will drip out into a container, it may take some time but it does the trick-The tube adapter goes into "2nd adapter", you can pull it out with pliers and make pouring easierP.S. oil change for my car took 5 minutes total

I got two oil changes out of my MV7400 and they were great. I'm now sold on the idea of vacuum oil extraction. Unfortunately, my MV7400 failed catastrophically during my third oil change. Oil came out of the handle and sprayed everywhere. To finish my oil change, I put the MV7400 in a 5-gallon bucket and put a plastic bag over the handle and kept pumping as the oil sprayed into the bag and then dripped down into the bucket. I was able to retrieve 3 of the 4 quarts of oil in the engine before I gave up.I'm not that upset about the failure of my MV7400. It's a fact of life that stuff breaks and sometimes even good products fail prematurely. However, I'm very upset about the way that the MV7400 failed. A simple loss of vacuum or a broken part would have been irritating but understandable. To have the device fail like the Deepwater Horizon, spraying oil all over myself and my garage, is unacceptable. No one should have to endure having an oil extractor suddenly turn into an oil sprayer. The design of the MV7400 needs to be changed to prevent this.Cost of Oil: $24Cost of MV7400: $75Cost of boots ruined by oil: $160Cost of whole roll of paper towels: $1Cost of damage to the environment: PricelessEdit: To be fair, I must admit the following. I re-read the instructions for my MV7400 and ran across the following:8. Remove the reservoir adapter from the reservoir, pour the used engine oil from the reservoir into a suitable container, then dispose of the oil in an appropriate manner.9. Rinse the evacuator reservoir, pump, adapter, and tubes with clean solvent or engine degreaser, and allow them to dry thoroughly.I did not do this. I have small cars that only hold 4 quarts of oil while the MV7400 hold twice that much. I left 4 quarts of oil in the MV7400 for months between today and my last oil change and doing so probably ruined the pump seals. However, this brings up two important points about the MV7400. First, why does the pump have to be in the oil at all? Other vacuum extractors do not immerse the pump in the oil and are unlikely to turn into oil sprayers unless overfilled. Second, I purchased a vacuum oil extractor to make my oil changes easier and cleaner. I'm fairly certain that disassembling the MV7400 and cleaning it as prescribed would be less convenient and messier than simply draining the oil in the old-fashioned manner.I now plan to purchase either a Pela PL-6000 or Liquivac Topside oil extractor. They're both reasonably priced and have a vacuum pump that is not immersed in the oil. Live and learn.
