2. Use the vehicle’s existing primary line as the fuel return line with modification to
the pick up as described below.
3. Use the vehicle’s existing return line (if so equipped) as the fuel return line. This
option applies only to vehicles previously equipped with fuel injection. If the
vehicle is not already equipped with a return line, some fuel tank modifications are
required for routing the return line through the sending unit plate back into the
tank. The first two methods listed below require some welding and should be done
by a professional radiator or fuel system repair shop.
RUBBER RETURN LINE METHOD
Drill a 5/16-inch hole in the sending unit plate adjacent to where the main line enters the
tank. This will be the hole for your return line. Insert a short length of 5/16-inch hard
line (available at most radiator shops) into the hole and weld it to the sending unit plate.
The hard line should extend through the hole 1 to 2 inches on each side of the plate.
Connect a length (at least 4 inches) of 5/16-inch rubber return line hose to the hard line
that will extend into the tank. Connect the rubber line to the fuel pickup line using tie
wraps.

BULKHEAD FITTING METHOD
Drill a 9/16-inch hole in the sending unit plate adjacent to where the main line enters the
tank. This will be the hole for your return line. Insert a #6 AN bulkhead fitting (available
at most radiator shops) into the hole, the narrow end of the fitting on the inside of the
plate. Apply a rubber washer or RTV sealant and fasten the fitting to the plate with the
