Hey all. I'm looking for a pressure/power bleeder adapter for the clutch master cylinder. I attempted to make one out of an old cap, but the cap is too flexible and leaks all over the place. If there's another vehicle that uses the same cap that's stronger, I could use that to make my own. But I'd prefer one I can just order and not have to worry about it. I tried a couple off Amazon, but they don't fit. Pics of the ones that DON'T fit are attached. Thanks.
****As much as I appreciate it, I'm not interested in people posting all the different bleeding methods. I know how to do it. This is about finding a pressure bleeder cap for the Clutch.****

Years ago I did just that... and it didn't leak. Just letting you know that it is possible to successfully do.

I've seen pics of older caps and they look much sturdier than the one I have (which is newer). I'm not sure which one you used, but the newer ones are flimsy and thin.

I wasn't aware that there was a difference between "older" and "newer" clutch master reservoir caps. The one I used was probably an original cap from the 80's.

You did say you used an "old cap".

Some good info here, V8 Archie's clutch bleed info and other Archisms

I have used these in the past. Just need to keep the gaskets in place and regulate the air pressure to single digits.

Any more, I just bleed the manual way with a hose in a bottle.

That's probably the secret to success. Back when I was still using this method to bleed the system, I just used a hand vacuum/pressure pump.

To me, purging air from a hydraulic system is so easier with vacuum than pressure or the gravity method.......

I recently bought new master and slave from Rodney Dickman along with his bleeder kits and was very simple 1 man operation per his instructions. Bench bled the master and installed. Swapped the slave and elevated the rear and used his 1-waay bleeder. Easy.

We've bled the clutch slave cylinders with a vacuum bleeder and have achieved good results.

Hi, I made my bleeders that looked like fieroguru's out of old OEM caps and left their seals in. I also had problems. Through experimenting I found that 5-7 psi worked for me. When I tried 10 or more psi I couldn't keep the caps from leaking out air. I never found any other cap that fit the clutch mc. Hope this helps, good luck, please let us know when you figure this out.

PS, forgot to mention I made my bleeder using one of those plastic containers that you pump up by hand and then press the sprayer handle that I had addaped to attach to the cap.
