NOTE
Procedure is same to remove No. 1
or No. 2 jet pump. Removal of No. 1
(left) pump is shown here.
1.
Disconnect hose (1) from jet pump (2). Use
grounded container to catch spilled fuel.
2.
Clean up spilled fuel. Use cloths (E135).
Do not puncture or scratch lining
of fuel tank. If lining is broken, fuel
penetrates and activates self-sealing
layers. Activated layers swell and trap
fuel. Activated green spongy material
also contaminates fuel system. This
makes it necessary to replace fuel
tank and flush fuel system.

Reach through hole in tank (3). Disconnect hose
(4) from jet pump (2). Carefully lower hose inside
tank.
4.
Remove four bolts (5) and washers (6).

(E80) and tape (E388).
