STEP 1: Removing & Preparing Fuel Tank: Continued
2. Disconnect overflow tube from the fuel tank.
3. Disconnect the factory suction and return line. The factory lines are removed by
pressing in on the two tabs located in the connecting harness. These tabs are
opposite of each other.
4. Disconnect the factory electrical harness located between the suction and
return lines on top of the fuel tank.
5. Before completing the next step review photos 1B, 1C & 1E, the closer the
suction tube is placed to the center of the fuel tank, front to back and left to
right, the more usable fuel there will be!
6. With the fuel tank empty of fuel now remove it from the vehicle.
7. As seen in photo 1A remove the lock ring on the top of the fuel tank.
8. Once the lock ring is removed, remove pick up module from fuel tank.
9. Reviewing photo’s 1B and 1C, place the lock ring back into place for
measurement reasons. Lay the grommet into proper location and use a punch
to mark the center. Drill a 1 ¼” hole, catch all debris, example cup.
10. Using photo 1D assembly the pick up assembly. Use pipe tape on the pipe
threads.
11. Insert the grommet into the 1 ¼” hole. Place the pick up assembly into
grommet, take measurements so the bottom of the suction tube is only 1/8” (no
more than 2 quarters stacked) from the bottom of the fuel tank.
12. Before cutting the suction tube triple check the measurements, it is much more
efficient to cut the tube to long and then correct to proper length than it would
be to cut to short.
13. With proper length being obtained with the suction tube kit, debur and flush
assembly. Place the assembly into the grommet as seen in photo 1E.
14. Reinstall install pick up module.
