Good idea. But make sure that you check the SG of the filtered used fluid. If there's rusty water in the fluid it indicates that the fluid has been watered down

Good point Peter. I only use the pump on my own cars and use a fluid made by a local business connected with the original supplier to BMC Aust.
The specific gravity of the fluid wasn't the main problem here. Early hydro cars squeaked so the formula had to have a 'lubricity' agent added.

I'm disappointed that you didn't use a period-correct Coke bottle. :lol:
