 Fuel Tanks. : Each wing contains an integral fuel bay, located between the front and rear spars, extending from WS 31.38 to WS 65.125. Fuel bays should be filled immediately after each flight to lessen condensation in the tanks and lines. A fuel filler cap is located on top of each wing and provides a fueling/defueling point for each fuel bay.
              Fuel Drains. " Fuel drains are located at various places on the underside of each integral fuel bay and throughout the fuel system. These drains are utilized to collect fuel samples for analysis. This sampling is accomplished by placing the fuel sample cup up to the drain valve, and depressing the valve with rod protruding from the cup.

Safety Precaution:

  1. Ground airplane first.
  2. Ground vehicle  to the same ground as the airplane.
  3. Bond vehicle  to airplane.
  4. Bond refuel nozzle to airplane.
  5. Ensure fire fighting equipment is positioned and immediately available.
  6. Do not wear clothing that has a tendency to generate static electricity such as nylon or synthetic fabrics.
  7. Do not wear metal taps on shoes.
  8. The airplane should be in a designated fuel loading/unloading area.
  9.  High wattage, pulse transmitting avionics equipment shall not be operated in the vicinity of the fueling/defueling operation.
  10. Use designated equipment for fuel loading/unloading to prevent contamination.
  11. During defueling, ensure anti-ice additive blended fuel and unblended fuel are not mixed.

VACUUM SYSTEM

By -
TTP B1-L3 ATA37 Cessna 172 B2-L2   V acuum system has a filter, vacuum gage, vacuum instruments, regulator valve, vacuum manifold,  low vacuum annunciator switches, engine-driven vacuum pumps and related plumbing.   With   Garmin G1000, the source of vacuum air is in the cabin and is pulled through the  system by the engine-driven vacuum pumps. This air goes through the gyro filter at the cabin inlet source  before it goes through the vacuum gage and gyro instruments. The vacuum is controlled by the regulator  valve. The regulator valve is on the aft side of the firewall. The vacuum air is then pulled through the  vacuum manifold and past the low vacuum annunciator switches and then into the vacuum pumps. Without Garmin G1000, vacuum pressure is measured by the low vacuum annunciator   switches in the engine compartment. The vacuum gage in the instrument panel shows the vacuum  pressure. Vacuum gag e gives a direct indication of the
