A pressure will be incorporated in the filter base. It will be used to indicate filter blockage. The pressure differential value is set at 14 in. Hg. ± 2 in.

The 6.2L uses a water in fuel warning system, which allows the user to guard against water in the fuel. The water is detected by a capacitive probe located in the filter base. Electronics within the probe will connect a ground (circuit 150) to the ground side of the water in fuel lamp (circuit 508).… Read More »

The bottom of the filter is a hollow water collector. (See Figure 4-19). Because of the greater density of the water, the water droplets will separate from the fuel oil. It will hold approximately 260 cubic centimeters of water (approx. 3-10%). A nylon fiberglass coalescent is used to blend the small water droplets into larger… Read More »

The engine fuel filter is a two-stage pleated paper type filter (Figure 4-20). The first stage consists of approximately 350 sq. inches of filtering area and will remove 96% of particles 5-6 microns and larger. The second stage is made of the same paper material with glass particles and consists of approximately 100 sq. inches… Read More »

See Figure 4-19. The purpose of the heater is to heat fuel, so that the filter does not plug with parafin wax crystals. This will allow the use of fuels at temperatures substantially below the cloud point of the fuel. The heater is electrically powered from the ignition circuit 39. It is placed in the… Read More »

The G-P series uses a Stanadyne Model 75 secondary fuel filter in 1983. See Figure 4-16. It is fastened using two bail clips. It is particularly important to place absorbent towels under the filter when changing it to improve cylinder and case valley drain and prevent fuel oil contamination of the clutch driven disc. The… Read More »

The 1982 C, K & P, and the 1983 C, K trucks use an intake manifold mounted secondary fuel filter, before the fuel enters the pump. This filter is an AC 10 micron paper replaceable element of the spin-on type. It is mounted to the rear of the intake manifold. See Figure 4-15. SECONDARY FUEL… Read More »

A Diesel cold weather package is used. This package consists of an in-line diesel fuel heater and the engine block heater. (Figure 4-14). The purpose of the heater is to heat the fuel so that the filter does not plug with paraffin wax crystals. This allows the use of more efficient #2 Diesel fuel at… Read More »

See Figure 4-13. If it should become necessary to drain water from the fuel tank, also check the primary fuel filter for water. This can be done as follows: 1. Open the petcock on the top of the primary filter housing. 2. Place a drain pan below the filter and open the petcock on the… Read More »
