How to remove anti siphon screen

It's an anti-roll over valve. IE, stops gas from spilling if the truck gets upside down.

Between the fill up spot and the tank is there a rubber hose that connects them?If so why not disconnect it and siphon from there.

When replacing the fuel pump in my 95 S10 I had to empty the tank. There was a ball captured at the fuel entry point of the tank that prevented getting a siphon hose beyond that point. It's captured in a 3-fingered manner and a stiff poke with a garden hose dislodged it into the tank. Beware once there, the only way to replace it is to remove the tank. You might consider adding a fitting to the truck's fuel line for purpose of getting fuel out. I'd first check to see if the 2002 has a "fuel pump prime" lead that will let you run the pump without the key on.

Thanks for the help, guys. Sounds like a good thing for safety. Pete

It does, right next to the fuel pump relay there will be a single hole
