Disassembly
DANGER
Gasoline is flammable. Use caution when storing
or handling it. Wipe up any spilled fuel before
starting the engine.
1. Park vehicle on a level surface and engage parking
brake.
2. Raise or remove the cargo bed or other attach-
ment(s). If bed is raised, place safety support on lift cylin-
der.
3. Make sure that the engine is stopped and the key is
removed from ignition switch. Allow engine to cool.
4. Inspect carbon canister and attached hoses for dam-
age or obvious leaks. A damaged or leaking canister
should be replaced.
5. Remove EVAP components as needed using Fig-
ures 11, 12 and 13 as guides.
A. If hoses are removed from the carbon canister,
note hose location for assembly purposes. Figure 11
identifies hose location.
B. If vacuum check valve (item 11 in Fig. 12) is re-
moved, note direction of arrow on valve body for as-
sembly purposes.
IMPORTANT: A plugged carbon canister or fresh air
filter can cause fuel pressure problems that result in
poor engine performance and also can lead to fail-
ure of the fuel pump.
Assembly
1. Install all removed EVAP components using Figures
11, 12 and 13 as guides.
A. If vacuum check valve (item 11 in Fig. 12) was re-
moved, make sure that arrow on valve body points
toward engine.
B. Make sure that evaporative system fuel hoses
are not kinked after installation. Also, secure all
hoses with hose clamps.
2. Lower or install the cargo bed or other attachment(s).
