Clutch reservoir
This morning my Lt4 had no clutch, there is no spill underneath the car or anywhere. I topped the fluid off, since it was empty, and now the clutch is fine again...
Anyway, what is the rubber hat´s function inside my clutch reservoir cap? Is it supposed to look like this? IT dosent allow much fluid in the clutch reservoir like this...

That rubber hat is an expandable moisture barrier. It is designed to telescope/accordian into itself to take up a small volume when the clutch master cylinder is full, then expand as the fluid level drops.
You have to compress/telescope/accordian the seal when you put it back into the reservoir....play around with it a bit, you'll get it.
Almost all brake master cylinder reservoirs and clutch master cylinders have these devices and they all work on the same principal...

The fluid level in brake master cylinder resivoirs drop as the pads wear but the clutch master cylinder resivoir fills as the clutch disk wears. That is why the hat on the clutch resivoir does not fold into the cap like the one on the brake. I made a mark on the resivoir when I replaced it so that I could easily find what level to fill to when the hat is out so that when the hat is back in the fluid comes to the full line.

Dont you level the fluid to the "full" mark, then "curl" op the rubber hat, and put it back on with the cap???

So, I can only say to fill the clutch master to the full mark, and collapse the rubber hat before installing it; it will then have room to move in both directions.

I think this is wrong, but it's been awhile since I bled my clutch system and I don't have access to my FMS at the moment to verify.

After the bleeding process is complete, fill the reservoir to 1/16" below the "Low" mark so that when the "clean and dry" moisture barrier is re-inserted and lid screwed on, the fluid level remains between the LOW and HI mark. This set up method provides the best level of atmospheric pressure isolation with in the hydraulic system.

I blaze few trails, preferring to go by the Factory Service Manual.
Only filling the reservoir to below the low mark sounds like "blazing new trails" to me......I don't care who the person is playing Lewis and Clark.
