WARNING

DO NOT perform fuel system checks, inspections or maintenance while smoking or near fire, flames or

sparks. Fuel may ignite, causing damage to vehicle and injury or death to personnel.

Personnel must wear fuel-resistant gloves when handling fuels. If exposed to fuel, promptly wash

exposed skin and change fuel-soaked clothing.

NOTE

Use a drain pan to catch residual fuel in hoses when fuel hoses are disconnected. Ensure all spills are

cleaned up.

If replacing more than one fuel hose at a time, tag hoses to ensure correct installation.

Remove and discard tiedown straps as necessary. Use new tiedown straps on installation.
