 The fuel pump canister has:
 -a body
 -an outlet valve
 -a slide valve.
 The body is hollow to contain the fuel pump. A mounting flange at the bottom of the body attaches the canister to the fuel tank. The fuel entrance to the canister is immediately above the mounting flange and a wire mesh strainer protects it. The slide valve closes to seal the fuel entrance to the canister when the fuel pump is removed. When the pump is installed it holds the slide valve in the open position.

 The canister has two primary fuel outlets. One outlet contains the outlet valve and is the fuel supply to the engine feed pipe. The other outlet has a sequence valve. A small opening in the side of the canister connects the fuel pump to:
 -
the pressure switch

 -
the jet pumps.
