Redline bottles and pump alternatives?

[Boris3]

Yeah, in the realm of possible and I do have the compressor...but I'd like to try it out in someone else's garage first. Mine's an attached to the house and the potential carnage has me cautious.

Much easier to make a pump from a small garden sprayer.  With the right attachments it also will make a good pressure bleeder.

Turkey baster and a 4 ft hose

I've used the methods from both post 1 and 2.  The option from post 1 is best and least messy.

I used the syringe approach to top off a leaking diff on the daily this evening. Worked pretty well actually. Wouldn't want to do this with a full fluid fill but not a messy as I thought it would be.

I ran into the exact same issue with my e46 last week when i was putting fluids in. I've got a 1-way pump i borrowed from TJ similar to what was listed at Pegasus, and the pump got me through both diffs, the trans, and the transfer case, however, from the get-go the cap just wouldn't stay on over the spring. So I had to grip it with one hand to keep the cap over it, and pump with the other, which was hella awkward - I basically cut the necks off of the redline bottles and just propped them up on some blocks so they were high enough where the hose would reach into where i needed to get it to while also being able to hit the bottom of the bottle. Then I was just really careful not to knock them over because again both hands were busy managing the stupid pump so I couldn't grab a bottle. Still made a glorious mess and ruined all the cardboard I had covering the garage floor. 

I was hoping this thread would have some magical bullet proof way that people who are smarter than I already thought of, but it seems like there isn't any universally accepted truth for the DIYer. 

If I'm ever independently wealthy, I'm buying everyone here a commercial grade pump.

I just use the pumps that don’t fit and deal with it. Swearing a lot helps

the amount of "god fucking dammit"'s that leave my mouth during this process is appalling but it definitely does help, you are correct.

And somehow you get those extra 4 pumps of fluid into the diff that weren’t needed, but decided leak out all at once

The royal purple 75-90 bottles you can buy at Advance thread perfectly to the transfer pump. I always forget to order Redline online but when I do I transfer it into royal purple bottle.
