And
@Gravity Aided don't panic! I should have mentioned, it was never going into a vehicle. I was trying to make the ultimate penetrating fluid. My most recent stove purchase (1927 Primus No 97) has a leaking non return valve that I am really struggling to get out. Plus Gas has been defeated and after some research discovered a 50/50 mix of acetone and auto transmission fluid when mixed into an immulsion is the last word in penetrating fluids.
I only wanted a tiny amount and not the litre on offer. Power steering fluid was from what I could tell at least almost the same and available in a smaller bottle!
I filled the pump tube with the mix I made and I'm sure some of it has disappeared!
