23. Install the fuel pump retainer ring into the fuel tank from the inside. The C-shape allows the ring to be inserted
through the smaller hole, to the inside of the tank, and the studs pushed up through the holes drilled in steps 11-15.
24. Place the installation ring over the retaining ring studs that now protrude from the top of the tank. With the foam
baffle fully inserted into the bladder/cup, Compress the baffle assembly, and insert it through the installation ring into
the tank being careful not to cut the assembly or your hands on the tank edge. Once the baffle assembly is in the
tank, manipulate it until it’s centered within the opening.
25. NOTE: COMPLETE THIS STEP ONLY IF YOU PLAN ON USING A RETURNLESS FUEL SYSTEM where the ECU
uses PWM to control fuel pressure. In this case you must drill a 1/32" hole thru the pipe plug indicated below. If you
are planning on using a traditional, return style fuel system please skip this step If you are unsure what your system
requires, please contact your EFI system manufacturer or Aeromotive for assistance.
26. Install fuel pump strainer and the foam sleeve on the fuel pump.
Position the fuel pump on the fuel pump hanger assembly such that from the bottom of the outlet cap to the bottom
of the fuel pump strainer is equal to the fuel tank depth. Mark the bracket and the black outlet hose so they may be
cut to the necessary lengths. Remember, take the time to measure twice and cut once!
Note: Failure to position the fuel pump strainer on the bottom of the basket assembly will potentially starve
the pump for fuel when fuel tank level is low, yielding poor drivability and reduced pump performance.
