3.
Remove the fuel rail from the intake manifold being careful when separating it from the fuel injectors.
4.
Disconnect the fuel pressure regulator from the fuel rail and set it aside. (If your vehicle has a purge valve mounted on the fuel rail, remove
the purge valve and it's bracket and set them aside.)
5.
Remove the fuel injectors from the intake manifold. Inspect o-rings (and fuel injector insulators if applicable) for any damage or wear and
replace if necessary. If they are in good condition, they can be re-used (The upper o-rings can be discarded. They will be replaced by the
four supplied 8mm I.D. x 2mm thick o-rings). Set the fuel injectors aside.

EDELBROCK FUEL RAIL INSTALLATION: (Note: The word "Lubricant" in the following installation instructions will refer to fuel system appropriate
lubricants for assembly of fittings, o-rings, etc. Such as: clean engine oil, silicone spray lubricant, brake cylinder assembly lube, or o-ring lube)
1.
Install the factory fuel pressure regulator to the Edelbrock Fuel Rail using the Fuel
Pressure Regulator Adapter, the two 6mm x 1.0-20mm long Socket Head Cap
Screws, the 1/2" I.D. 1/16", and the stock fuel pressure regulator o-ring (See Fig.
2) . (If your vehicle has a purge valve mounted on the fuel rail, attach the purge
valve and bracket to the Edelbrock Fuel Rail at this time.)
2.
Install the Russell Honda Fuel Fitting using one of the -8 AN o-rings, using a light
coat of lubricant on the o-ring and the threads of the fuel fitting.
3.
Using a light coat of lubricant on the four 8mm I.D. x 2mm thick o-rings, install the
o-rings onto the factory fuel injectors. You may then install the factory fuel injectors
into the Edelbrock Fuel Rail. (On fuel rails machined to accept Bosch style injectors,
install them in the same manner as the stock injectors)
4.
If the two 1/8" NPT ports are not going to be used, install the 1/8" NPT plugs using
a liquid teflon or pipe sealant that is compatible with fuel on the threads and install
them into the fuel rail. Make sure to let any pipe sealant or liquid Teflon fully cure
before running fuel through the fuel rail.
5.
Using a light coat of lubricant on the stock fuel injector o-rings and if applicable, fuel injector
insulators, insert them back into the intake manifold. Carefully press the now assembled fuel
rail with the fuel injectors into the intake manifold and secure with the factory hardware (See
Fig. 3) . (Fuel rails machined for Bosch-style injectors will require the use of the supplied
fuel rail spacers. On fuel rail part #4797, install the spacers under the fuel rail. On part
#4799, remove the fuel rail standoffs, and re-assemble with the M-8 spacers under the fuel
rail standoffs, and the M-5 spacers under the fuel rail.
6.
Re-attach the stock fuel inlet and return line. (On vehicles where the location of the fuel
pressure regulator has been moved to the end of the fuel rail, replace the factory return line
with a length of 6mm fuel hose if needed). (If your vehicle has a purge valve mounted on
the fuel rail, re-attach the purge valve hose). Reconnect the fuel injector wiring harness and
re-attach the fuel injector support to the fuel rail. Some applications may be attached by the
fuel rail mounting hardware.

NOTES FOR CUSTOM OR RACE FUEL SYSTEMS:
1.
The Edelbrock Honda/Acura Fuel Rails are equipped with -8 AN, o-ring
threads at each end of the rail. Each end of the rail requires the use of a
-8 AN, o-ring sealed fitting (For examples, see Fig. 4) . Use a light coat
of lubricant on the o-rings and threads of the fittings you use. A remote
mounted fuel pressure regulator must be used with this setup.
2.
The Edelbrock Honda/Acura Fuel Rails are equipped with two (2) 1/8" NPT
ports on the top of the fuel rail. These can be used for a nitrous system fuel
supply, or for a fuel pressure gauge sender. Use a small amount of fuel
system safe liquid Teflon or pipe sealant on the threads of your fittings when
threading them into the Edelbrock Fuel Rail. Make sure to let any pipe
sealant or liquid Teflon fully cure before running fuel through the fuel rail.
