Fuel Restriction
 

How would you change or clean the screen inside a 40gal plastic tank?
(where the fuel gets sucked up from the bottom of the gas tank)

You need to pull the feed tube from the tank and once it is out, clean the screen. Usually, you would need to disconnect the fuel line and unscrew it. At least in a metal tank that is how it is.

ok thank you, I didn't know that the metal line where the fuel line connects to comes out like that.
