No, There is only one and it is inside of the fuel tank.
Assuming this is a gas engine with one fuel tank, one.
Does it have fuel, spark, compression?

1999 Chevrolet Tahoe (gas 5.7l 350 cu.in.) fuel tank capacity 27 gallons
It is on the inside of the frame rail by the cross member on the driverside.
It is located in the gas tank
no it does not, you will have to remove the fuel pump relay or fuse to shut it off.
YES it is. GM had a problem with the fuel pumps making noise and still does.
