WARNING
The JP-8 and diesel fuels used with the MTRCS are combustible and highly
explosive. Do not smoke or use open flame when performing maintenance. Flames
and explosion can occur resulting in severe injury or death.
The JP-8 and diesel fuels used with the MTRCS are toxic. Always wear eye, face,
and hand protection when working with or around fuel. If fuel contact is made with
eyes, flush your eyes and seek immediate medical attention. If fuel contact is made
with skin or clothing, remove contaminated clothing immediately, clean your skin with
a mild soap or cleanser, and rinse with clean water.
CAUTION
The fuel tank will retain a small amount of fuel even after it has been drained. Fuel
lines will have some fuel in them that will drain out when disconnected. Use cleaning
rags to clean up any spills when performing the following tasks.
1. Drain fuel from fuel tank into suitable container (WP 0012, Service).
2. Disconnect fuel sending unit electrical connector P4/J4 (Figure 3, Item 1) on wire harness (Figure 3, Item 2).
