7. Route the remaining wires (White, Black, Blue, and Yellow "from fuel gauge") through the fire wall and

route the wires along the frame rail. Insure the wires do not come in contact with any moving parts. Use

a small grommet or use a rubber boot when routing wires through firewall to insure wires will not chaff

and create a short.

8. Apply a gasket sealer to both sides of the gasket of the Sending unit. Install the Sending Unit Assembly

to the tank using self-tapping screws. DO NOT BEND FLOAT ARM WHEN INSTALLING

SENDING UNIT INTO THE TANK. Attach the Sending unit harness to the tank. The Yellow wire

attaches to the center brass post of the Sending unit. The Green wire attaches under any of the self-

tapping screws.

9. Connect the 3/8" hose to the 3/8" supply port/check valve on the Sending Unit using a hose clamp.

Connect the long 5/16" hose to the 5/16" black nylon return port using a hose clamp. Connect the short

5/16" hose to the 5/16" aluminum vent port using a hose clamp. Inspect all hose clamps to insure proper

seal.

10. Remove the lock-bar from the auxiliary tank and throw away shipping screws. Center lock-bar in bed

and drill a 3/8" hole approximately 1" from each end of the lock-bar through the lock-bar and truck bed,

then place a 3/8" carriage bolt in each hole. Insure the auxiliary tank is placed on some sort of isolation

mat. (Drop-In or Spray-In bed liners will work. Mud Flaps or a rubber mat will work also). Position and

center the auxiliary tank in the truck bed. The front hold-down tabs of the tanks will slide under the

lock-bar. Drill a 3/8" hole in the rear hold-down(s) of the tank and bed, and then place a bolt in the hole.

Route the wires and hoses under the truck. Insure the hoses are properly tied and no sharp bend was

created. Place one flat washer, one lock washer and one nut on each bolt. Tighten all bolts.

11. (A) ONLY TRUCKS WITH INTERNAL FILL VENT LINES NEED TO FOLLOW THIS STEP,

ALL OTHERS SKIP TO 11 B. Trucks with an internal fill vent line it will be necessary to use the

push-in adapters (not included with kit) on the factory fill neck in place of the vent-line adapter.

Disconnect the factory fill from the body of the truck. Pull the assembly down the underside of the truck

to make it easier to work on and prevent metal shaving to fall into factory tank. Using a 19/32" drill bit

(a 9/16" bit may used, only if the 19/32" cannot be found), drill two (2) holes into the metal portion of

the factory fill neck. *Note: Insure that the holes will be on the side of the factory fill neck facing the

engine side of the truck when it is bolted back to the factory position. Remove any shaving that may

have been produced. Place a bead of gasket sealer around the ring of the rubber boot of the adaptor, (do

not install the elbow at this time). Insert the rubber boot into the 19/32" hole of the factory fill neck.

Insert the metal elbow into the rubber boot. Insure that it has a snug fit. Place one long cable-tie around

each of the push-in adapters.

NOTE: In some later year GM/Chevrolet vehicles, you may be required to pull excess factory vent hose

and remove excessive slack before installing Vent-Line Adapter.

11. (B) Locate the factory fill neck on the inboard side of the truck bed. The vent line adapter has both a

5/8" & ¾" step, the same vent line adapter will be used for both sizes. (If it is a 5/8" vent line, place it upon

the 5/8" portion (lower step) of the Vent-Line Adapter. If it is a 3/4" vent line, place it upon the 3/4" portion

(upper step) of the Vent-Line Adapter.) Mark the factory vent line where the cut should be made, insuring

that you will have enough factory vent hose to slide over the adapter. Cut a small section (approx. 1" or

more) out of either the 5/8" or 3/4" factory vent line. Place a large hose clamp on each side of the cut

section. Insert the vent-line adapter and tighten the #12/#10 hose clamps. NOTE: On some trucks with metal

fill vent lines, it will be necessary to cut a portion of the metal tube and add the applicable rubber hose to

install the Vent Line Adapter. Do not "kink" the vent hose. It does not matter whether the 3/8" fitting or the

5/16" fitting face the factory tank.
