Yeh....ask me how I know....

Reason for this -- AutoH carries the URO for that particular item. Chinese Junk. I replaced all mine with URO about a year ago and it split on me a few months back and I had the exact same symptoms.
Replace it with an OE hose. It sucks since its about $15 @ the dealer, but at least you know it will last a lot longer than 6 months that's for sure.

I always wondered if there was a product that would prolong the life of these hoses by keeping them supple...?
You can always wrap some tape around the hole if you need the car today, although it sounds like a bad crack.

Why do you think you need a new FPR? They generally never need to be replaced. If the diaphragm is broken inside you will see raw fuel going through the vacuum tube out the other end. If you don't see that, I would leave it alone.

You check the mixture via the X11 connector on the driver-side fender. Unscrew the cap and probe pin's 2 and 3. (2 is ground...3 is the mixture ratio). You want 50% or ~.65v fluctuating.
