DESCRIPTION: Edelbrock Fuel Pumps are for street high performance or marine use where there is a demand for high volume fuel delivery. These
pumps are compatible with both gasoline and alcohol fuels. They have been thoroughly tested and proven to have flow capacity significantly greater
than other popular mechanical fuel pumps used for street applications. Performer RPM Street Fuel Pumps fit the following applications:
#1721 - 262-400 C.I.D. Small-Block Chevrolet
#1722 - 396-502 C.I.D. Big-Block Chevrolet
WARNING: Personal protection must be given careful consideration. The pump body itself is spring loaded with a heavy diaphragm spring. If the unit
is taken apart for adjustment or re-positioning of the lower pump body, extreme caution should be taken when assembling and disassembling the upper
pump body to and from the lower pump body. Upon 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.
IMPORTANT NOTES:
• Inlet and outlet ports are tapped to 3/8" NPT.
• Edelbrock repair kit #1799 is available for you to replace critical
components of the pump when necessary.
• Edelbrock Universal Fuel Pump Kit #1797 is a machined aluminum
plate that can be used to relocate the inlet and outlet fittings to the
bottom of the fuel pump for improved clearance in some engine
compartments. (Required for 1970-1/2 to 1981 Camaros as well as
many other applications.)
Installation of the mechanical fuel pump is the same as for OEM pumps. If uncertain of the procedure to follow for your particular vehicle, consult the
appropriate repair manual for your model vehicle. Note that the fuel inlet and outlet of the Edelbrock Street Performance Fuel Pump is much bigger
than original equipment (3/8" NPT) and that a Universal Fuel Pump Adapter #1797 is available if the larger physical size of the pump requires relocation
of the inlet and outlet fittings.
NOTE: On some 351-W Ford engines there may be casting flash on the front cover which will interfere with proper seating of your new fuel
pump. File this area flat for proper gasket seating.
RE-POSITIONING THE LOWER PUMP BODY: The lower pump body may be re-positioned as needed to allow better alignment of the fittings for
specific applications.
1. Referring to the exploded view on the following page, remove ten allen head screws from the perimeter of the pump pulsator cover and separate
lower fuel pump body from upper fuel pump body.
2. Rotate lower pump body to desired new position and start but do not fully tighten the ten allen head retaining screws.

shield between fuel pump and wheels to proven dirt from plugging
pump vent hole.
