Yes it will damage the evacuator reservoir and turn the fittings gummy over time. We had two separate evacuators at my shop- one for oil and the old one my boss destroyed was only to be used for gas. It basically collapsed the tank. It didn’t leak, but looked horrible and it still worked fine. Also, I did not get blown up. Any mechanic will tell you, a customers fuel pump never goes out with a 1/4 tank of gas in the car. Usually, its full or 3/4 of the way full. 20-30 gallons in the tank makes removing the tank a little difficult without sucking some gas out first. Advice: buy two, or immediately transfer gas to a proper storage container and clean out the evacuator and fittings.

Q: Has anyone used it to do a complete transmission flush,and if so how?

The idea of using Mityvac is to avoid mess. Yes I used it for complete flush, replaced 3.8 qt of fluid four times within 100 miles, fluid is bright pink even after 800 miles and not a single drop on the floor. Have patience, this thing will do the trick. Alternatively you can disconnect fluid outgoing line to trans, start the car wait for 1/4 of your tranny fluid to be collected, stop the car, replace the fluid with new, repeat 4 times and you are done, but there may be spills and you don't require a MityVac, it just does your job easy and clean. Pick your choice.

Q: Can this be used for brake fluid?

If ypu want to use for brake fluid and coolant buy 7075x01 gasket or buy a send extractor CTA 7073, that pump comes with the anti corrosive seals on them and is only like $3 more then the pumps with oil seals on them. You can do brake fluid with this but you'd need to wash it out within 10 mins of have brake fluid inside, eventually the gasket will let air into pump and you'll get the drips when extracting fluids. I'd just use this to do it and buy the 7075x01 seals to change them to when this starts dripping eventually. You'll need to change them out eventually anyway, even if you only do oil extraction.

Q: what all you guys use to clean the inside of the tank so will not contaminate the clean fluid for dispensing

I've used mine to pump out hydraulic /transmission oil. I clean the tank by running a pint or so of gasoline through it prior to putting the clean oil in it. This has worked fine.
