I appear to have an aftermarket Master Cylinder on my M38. The cap has no vent hole and the nut is bigger than the standard issue one. Do you know if this will thread into my existing MC?
Willys Jeep Parts Tech:
It should. Most master cylinders of the era have a standardized cap thread.

Ack! I just ordered this, but now realize it may not fit my 1948 CJ2A master cylinder. Do you know if it will? I don't see that cap in your offerings.
Willys Jeep Parts Tech:
It will screw on but you will have a hold in it for a vent.

I want to use a pressurized brake fluid bleeder - and the old style cap already has a threaded hole. Can you tell me the hole dimensions/thread?

will this fit on an FC-150/170 master cylinder, that would be helpful with filling that since it is just under the speedometer. it also may be helpful to use for filling on all trucks and jeeps with a hose coming up under the hood to fill these hidden m/cs.

We don't list it to fit, but if you have the right master cylinder then sure.
