@Gary. Some post/threads from you in the past your concern was about using the windscreen washer bottle for your water/meth injection. At that stage I was not sure. Gladly I can report the following:
1.Yes you can use the windscreen washer bottle.
2.But mix must never be different from 50/50.
3.That mix will not harm anything on your plastics outside the car or on paintwork or alike.
4.Pump must be lower than washer bottle.
5.Make sure what ever liquid was in your washer bottle is totally removed and cleanly washed, to prevent any other type of chemical reactions.
Advantages: Do I need to spell this out??? 🙄 🙄
I think I am going to walk this route. 8)
