Fuel filter depressurize?

i drive a 2001 s10 i want to change the fuel filter. my gas light is on and i was wondering if i still have to depressurize it first if so how do i do that? if not what would happpen if i didnt?Fuel filter depressurize?Just crack open the fuel filler cap, that will release most of the pressure and stop fuel pouring out when the filter is disconnected.Fuel filter depressurize?You can depressurize it on the fuel rail under your hood. The valve looks similar to the air valve on your tires. Even if you don't depressurize, it is still OK to replace the filter. It may squirt a little gas, but not much. Just place a rag over the connection as you disconnect it to be safe. A Haynes or Chilton's manual for your vehicle will give you details on where to find you filter, how to disconnect it, how to depressurize etc. It would be a good investment to get the manual because of your vehicles age. Other things will begin to need replacement and the manual can show you how on almost any repair.Fuel filter depressurize?can just loosen fuel line a little at a time
