fuel filter changing

let the fuel pressure off the system and go in under the rear seat to get at the access hatch to get at the pump and filter in the tank.

there is no fuel filter it has what they call a strainer in the fuel tank attatched to the fuel pump this is excessable by removing the back seat. there are two clips that slid one way or the other to remove the seat. i found when changing the plugs when installing them i use a 3/8 inch rubber hose the prevent cross threading
