•DISASSEMBLY:
1. After removing fuel pump from engine, remove twelve allen head
screws from the pump pulsator cover and separate from lower fuel
pump body.
2. Remove eight screws from the valve retainers (7) in the lower fuel
pump body; remove valves (5) and old gaskets (6).
3. Remove the pump diaphragm assembly (1) by pressing into casting
and unhooking from fuel linkage rod (10).
4. Remove oil seal (12) and oil seal retainer (13).
5. Grind (don’t use chisel to cut) rocker arm pin (8) end and remove
locking washer (9). Drive rocker arm pin through casting and remove
rocker arm assembly. NOTE: Drive rocker arm pin from side
previously ground.
•CLEANING:
Clean all parts that are to be re-used with a commercially available
carburetor cleaner. Follow instructions provided with the cleaner.
Make sure that there is adequate ventilation when using cleaning
solvents.
•ASSEMBLY:
1. Install the six valve gaskets (6), six valves (5), and two valve retainers
(7) in the lower fuel pump body. The valve retainer screws should not
be torqued to more than 25 in./lbs. The valves should be installed in
the following manner:
The “inlet” port of the lower fuel pump body is identified by the
embossed letters “in”. The valves on this side of the casting should
be installed with the “spoked wheel” side up. The opposite or
“outlet” port is not so identified. The valves on this side should be
installed with the “spoked wheel” side down. Valve retainers (7)
should be placed so that their ends will exert a downward pressure
on the valves (see illustration).
2. Install new pulsator diaphragm (2) on the lower fuel pump body
using two center allen head screws. Torque to 35 in./lbs.
3. Install the new oil seal (12) and retainer (13) in the upper fuel pump
body. The oil seal retainer should be tapped flush with the casting.
4. Assemble the rocker arm, linkage (10), and bushing (14) together.
Install the new rocker arm return spring (11).
•PLEASE study these instructions carefully before installing your new fuel pump rebuild kit. If you have any questions or problems, do not
hesitate to contact our Technical Hotline at: 1-800-416-8628, or e-mail us at Edelbrock@Edelbrock.com.
•DESCRIPTION: This kit contains all parts necessary to rebuild all Edelbrock Street High Performance and Racing Fuel Pumps #1711, #1712,
#1715, #1721, #1722, or #1725. Your fuel pump was manufactured and assembled to exacting specifications and strict quality control
standards. Care should be taken when rebuilding this pump to ensure continued satisfactory performance.
WARNING: Personal protection must be given careful consideration. Eye protection should be worn at all times, especially when grinding and
peening over the rocker arm pin. The pump body itself is spring loaded with a heavy diaphragm spring. Extreme caution and care should be
taken when assembling and disassembling the upper pump body to and from the lower pump body. Upon re-installation of the fuel pump on
the engine, care should be taken to ensure that all fuel lines and fittings are properly installed, tight, and not leaking fuel.

INSTALLATION INSTRUCTIONS
5. Press the replacement rocker arm pin (8) into the fuel pump body
casting and through the rocker arm assembly. Install the rocker arm
pin lock washer (9) and “peen” the pin tightly over this washer.
6. Apply grease liberally to the pull rod end of the diaphragm (1). (The
diaphragm’s pull rod end must be inserted through the oil seal. The
grease will prevent any damage from being done to the seal during
insertion.). This kit contains two diaphragm springs. Use both
springs for Racing fuel pumps or the larger spring only for Street
High Performance fuel pumps. If you want to install both springs in
a fuel pump originally equipped with the single low-pressure spring,
please note that Racing fuel pumps MUST use a fuel pressure
regulator to prevent carburetor flooding. Place the new diaphragm
spring(s) (3) on the diaphragm and pull rod assembly (1). Insert the
diaphragm pull rod end through the oil seal and “hook” the eyelet
hole of the pull rod onto the rocker arm linkage (10).
7. Assemble the lower fuel pump body to the upper fuel pump body,
with the diaphragm and diaphragm spring attached. Make sure the
diaphragm and threaded casting holes are all aligned. The inlet and
outlet ports of the lower fuel pump body should be at right angles
(90°) to the rocker arm assembly.
8. Start but do not fully tighten the ten allen head retaining screws.
Before fully tightening these screws, the rocker arm must be
actuated to and held in the “full stroke” position. This is done to
ensure that the diaphragm will be pulled to and held in its maximum
working (flexed) position while the retaining screws are torqued tight
in two steps. First to 15 in/lbs, and then to 35 in/lbs in a criss-cross
or “star” pattern to ensure even, progressive tightening. This
procedure will ensure against premature diaphragm wear and
subsequent failure due to over-stretching of the diaphragm material
when in the full stroke position. Another by-product of an improperly
set diaphragm is erratic fuel flow and pressure. NOTE: This
procedure can be assisted by holding the fuel pump in a vise or
appropriate fixture, and holding the rocker arm down with a pipe or
similar tool.
After re-installing the fuel pump, run the engine and check
for fuel leaks and proper operation. Correct as necessary.
