What is this fluid leaking??

Cranked my truck this morning and let it warm up for probably 10 minutes then came outside and saw a big puddle underneath it. Probably 3 feet long and 2 wide, was coming out of the plate that's behind the oil pan towards the back of the truck. Fluid is clear, real gritty like oil and smells like gas. I'm thinking it may be brake fluid because my brakes have really became un-responsive in the last week. But what stumps me is where the leak is dripping from. After I noticed the leak I was in a hurry so I backed my truck up about 20 feet to get it out of the way then killed it. The entire time the truck was cranked that fluid came out of the plate behind the oil pan. As soon as I killed it the leak stopped. Any suggests to what it is the location of where it's touching the ground from confuses me especially since it smelled like gas too, was in a hurry so took the other truck and left so couldn't get a look under the hood or pictures. All I saw was it's leaking from the circular plate behind the oil pan. It's a 96 f350 5 speed

If its brake fluid it is probably coming from the clutch slave cylinder getting ready to go out. My slave just went out in my ranger like this last week.

How hard do you think it is to replace it? I probably don't know enough to replace it, but wonder what it'd run to replace with labor?

Idk, I've never worked on a manual in these trucks. I've always had automatics.

I'd assume its an internal slave, of which requires dropping the Tranny to replace it since its right on the input shaft behind the clutch

Crap ok, thanks for the help! Think I should replace anything else while the trans is down?

Just look at your clutch to make sure nothing is worn down. You might want to get that whatever type of clutch disc if yours is stock. I'm sure someone will chime in with what it is

Probably fuel. Did you look in the engine valley?

If the clutch is operating properly, it's NOT clutch hydraulic fluid. If it leaked that much, your pedal would be on the floor with no action. And it wouldn't leak/stop with the running/stopping of the engine.

Put some white cardboard underneath the truck and run it. Check the color of the leaking fluid.

Sorry guys didnt check forum til now, it was brake fluid for sure, I'm not sure for what reason I thought it smelled like gas. It was the clutch slave cylinder, I looked up under the truck and yep, thats where the leak is coming from. As the wrecker pulled it up on it poured out a ton more brake fluid... Also when I came back home yep it had a puddle under it of more brake fluid in the place I moved it to, just not as big as the other one where I had it running at, when dirtydiesel said that's probably what it was he was dead on. Back to the 24 valve for a little while haha
