Task Instructions
1. Place a new 14mm ID copper washer, that came with the new filter, on the 14mm adapter fitting. Thread it into the new 6.5 MICRON FUEL FILTER. Torque to 260-280 in-lbs using two 3/4 wrenches. Figure 174
2. Place a new 12mm ID copper washer, that came with the new filter, on the 12mm adapter fitting. Thread it into the new 6.5 MICRON FUEL FILTER. Torque to 180-200 in-lbs using a 7/8 and 3/4 wrench.
3. Use a 3/4 wrench to hold the 12mm adapter fitting at the fuel filter outlet and a 11/16 wrench to torque the -6 AN B-nut to 110-130 in-lbs. Figure 173
4. Locate the fuel filter assembly in place on the aircraft and loosely thread on the -6 AN B-nuts. Figure 172
5. Position the fuel filter assembly so that there is 0.75 to 1.25-inch clearance between the top bend of the filter bypass tube and the carbon wing spar. (This slightly tipped back positioning ensures clearance to the headliner.) Snug the connecting -6 AN B-nuts finger tight.
6. Install the B-clamp around the fuel filter, install the #10-32 nut and torque to 20 in-lbs with a 1/4 wrench, verifying that the specified filter orientation established in the last step has been maintained.
7. Use a 3/4 wrench to hold the 14mm adapter fitting at the fuel filter inlet and a 11/16 wrench to torque the adjacent -6 AN B-nut to 110-130 in-lbs.
8. Use a 15/16 wrench to hold the check valve and an 11/16 wrench to torque the adjacent -6 AN B-nut to 110-130 in-lbs.
9. Use a 13/16 wrench to hold the union fitting at the fuel pressure relief block and an 11/16 wrench to torque the -6 AN B-nut to 110-130 in-lbs.
10. Turn on fuel valve, turn on master power, turn key to A position, and check for leaks.
11. Install headliner. (Headliner Installation)
