Clutch Problems

So my new jeep I got from my uncle never did work right, something is wrong with the clutch. He thought the slave cylinder needed to be replaced, which is inside the bellhousing. When you tried to work the clutch, you had to pump it for it to even halfway work. I was driving it down the street in first gear just to see if I could get the clutch working when, while I was pumping it, I just lost all pressure and the pedal goes straight to the floor with no resistance. I checked underneath and found brake fluid practically pouring onto the pavement. For some reason, where the clutch line goes into the bellhousing, there is a small rubber tube that comes out, looks homemade. I put some more fluid in the clutch and got my brother to press on the pedal while I was underneath and sure enough, Fluid just came pouring out of that rubber tube. does anyone know what this means and what I should do? THanks alot

Replace the slave cylinder. Ya might as well do the clutch and resurface the flywheel while you're in there.

Do NOT resurface the flywheel. The wrangler manual specifically warns that the Jeep flywheels are slightly domed, and that resurfacing will screw it up.

Lightly hand sand it if there is glazing on the surface, but don't get it anywhere near a lathe.

Do you know what the "domed" surface does? Nothing. Supposedly it helps for smoother engagement of the clutch. I don't buy it. Resurfacing a flywheel is common practice when replacing the clutch.

Resurfacing is common with flat-faced flywheels. The dome helps with centering the clutch plate to the flywheel, and lets it slip over a broader pressure window when engaging. Helps keep it from grabbing/bucking when taking off. People have resurfaced it and complained about it grabbing afterwards.

Alright.....I guess it may depend on the person. Although. Someone who does not know they are buying a jeep that "had" a flywheel resurfaced will not know the "grab" difference there is(ever was). Resurfacing the flywheel will cause NO harm.
