Always wear safety glasses/goggles at all times.
Keep fuel away from open flame or any spark (ignition source).
Keep at least a B-C fire extinguisher within easy reach when working with fuel or on a fuel
system.
Do not work on a fuel system when engine is hot; fuel can be ignited by a hot engine.
Post signs that read, "NO SMOKING WITHIN 50 FEET" when working with open fuel lines or
fuel tanks.
Direct contact with a high pressure fuel spray may cause serious injuries. Avoid direct contact
with fuel spray. If fuel spray penetrates your skin, get medical aid immediately. Eye protection
and rubber gloves should be worn when working with fuel.
NOTE
Individual plungers are used in the fuel injection pump to provide fuel to each individual injector.
A worn or damaged fuel injection pump plunger will only affect one cylinder.
Make sure to tighten fuel injector nozzle fitting after each cylinder is tested.
