97 Bravada

Since I have purchased this vehicle I have done nothing but throw money at it. Is this normal for Bravada's? Plus, could someone tell me where the fuel filter is? I believe I'm smart enough to know where it is even if I am female, but when going to purchase one for replacement at AutoZone they told me something very peculiar about the fuel filter and I just wondered if they were yanking my chain because I am blonde.

The fuel filter is mounted on the frame rail under the car about the middle of the drivers side front door and it's held on with a clamp.
The procedure calls for the fuel pressure to be relieved before you disconnect the fuel lines as they can hold high pressure for a long time.
