Is this a one off home made tool?

Going through some boxes of Jag parts , looking for the missing Door parts , I come across the Clutch reservoir cap , that was on the car when I got it , over 40 years back .
Has a hole drilled in it , and a tyre valve added , I guess to help bleeding .
Not that I have ever had a problem bleeding the clutch !

Gee, what could POSSIBLY go wrong with that design?


about 30psi lol
but on saying that , not sure how old the Easy bleed is , diffrent caps , you connect to your tyre valve , same principle :thinking:

It’s a question of volumetric issues…:grimacing:

If I were going to use that I would certainly stick to a hand tire pump, not a compressor!
