Clutch Reservoir Rubber Cup

[Garrcus]

Alright so after doing a bunch more research online I found a couple more forums discussing this, it turns out that what the GM parts guy told me is correct. They do not make the cup diaphragm any longer and you cannot even buy one in a master cylinder kit or any other clutch kits sold. So if you have one treat it with care.

The jeep cherokee replacement cap with the seal integrated into the cap itself is my next option but I am worried that since there will only be a seal at the rim and nothing protruding down into the reservoir that it will not operate properly. Correct me if I am wrong but the point of that cup seal is to eliminate the possibility of air and moisture getting into the system by taking up that space and also acting as a fill line as to not overfill the reservoir. So should I just use the seal-in-cap replacement and fill it all the way up to eliminate the empty space or judge the fill line as to where the bottom of the cup seal would have been and leave the rest of the space empty? I really don't know if that will cause any problems or not?

Thanks again guys.

Not to sound to simple here but why don't you just try it?

Yeah, that is my next option, just looking to get as much info as possible before trying this. Money is tight and I just want to try and avoid having to replace other parts through my ignorance in the area. I'll let you guys know how it works out,

Thanks again for all the help.

Resolution:

Alright so I went ahead and ordered the 91-97 Jeep Cherokee cap replacement. The cap is actually the exact same cap and comes with a new diaphragm somewhat similar to the old one which is awesome... problem solved. Working condition--so far so good.

Thanks again to all of your feedback guys.
