I had a leaking master cylinder and brake fluid made contact with my exhaust manifold once. Instant melt down. Brake fluid is highly corrosive and flamible. I am very aware of leaking fluids under the hood now.
On another note, I work on Jeeps/Eagles all the time installing the Motorcraft 2100 and 2150's. I am always amazed at how bad and rotten peoples fuel lines are. This is common sense stuff guys. Keep your hoses fresh. I'ts cheap, fast and you always end up finding something else that requires attention when you're routing around the engine bay.
