General Homemade brake bleed pressure device

I cannibalized my old gunson eezi-bleed today and made a pressure bleeder that doesnt require me to remove the spare wheel. Made it from a pump sprayer that was £2.50 from wilko. If you dont have an old leaky eezi-bleed you could use some plastic tube and an old master cylinder cap. I will add a pressure gauge when I can find an old one or pick one up cheap.
