R&D FX-SHO/FZR/FZS
FUEL PRESSURE REGULATOR KIT
R&D offers a Yamaha FX-SHO/FZR/FZS model specific fuel pressure regula-
tor system allowing custom fuel pressure tuning to the EFI fuel systems fuel
pressures. The R&D Fuel Pressure Regulator System offers a wide range of
setup possibilities. Base fuel pressure is adjustable from 5 to 60 PSI. The R&D
fuel pressure regulator can also be set up to allow “rising rate” fuel pressure at
a 1 to 1 ratio (One pound of fuel pressure gain over base for every pound of
boost gain). R&D offers two types of fuel pressure regulator set ups. Part
#802-00080 will come completely assembled and ready to install. The R&D
Pro System is 100 percent complete, installs directly to the top of the fuel
tank, and connects directly to the fuel rail with OEM security lock connectors
with no modifications. For the R&D Fuel Pressure Regulator only use part
#801-25010, which comes complete with 90 degree barbed brass fittings for
use with push on type hose and Oetiker style clamps for security. R&D offers
high performance fuel hose that can be purchased by the foot, as well as the
Oetiker style clamps. The R&D bypass style regulator system is capable of
handling any fuel pump up to 250 GPH. Replace “Deadhead” regulator
performance and experience the full flow volume and rock steady fuel
pressure that only a dynamic R&D fuel pressure regulator kit can produce.

REGULATOR BLOCK
OFF KIT
R&D offers a Fuel Pressure Regulator Block
off Kit which will allow the OEM stock in tank
fuel pressure regulator to be removed, blocked off, and replaced with a billet
part which is mandatory when installing an aftermarket externally adjustable
fuel pressure regulator system. The OEM in tank fuel pressure regulator
is fixed to maintain 40-43 pounds of fuel pressure at all times. For high
performance applications where horsepower is boosted, it is necessary to
install larger flowing fuel injectors and be able to tune the fuel pressure up or
down as needed. Most factory race teams are running 65 plus pounds of fuel
pressure along with higher flowing fuel injectors and externally adjustable
pressure regulators. The R&D has a complete line up of fuel pumps, fuel
injectors, fuel pressure regulators, fuel gauge, and fuel hose accessories all
designed specifically for the Yamaha SHO. All R&D fuel injection parts and
products meet Coast Guard, I.J.S.B.A., and APBA approval.

The R&D Fuel
Pressure Gauge
Adaptor Tool is
designed to be a plug
in fuel pressure gauge
that needs no modifi-
cations to install and
use. Simply disconnect the OEM locking fuel connector from the fuel rail and
plug the gauge tool directly into the connector. Plug the locking connector
supplied on the R&D tool onto the fuel rail and lock. Use the tool to verify fuel
pressure and fuel pump condition. Use the tool to set and verify base fuel
pressure settings on the R&D Rising Rate Fuel Pressure Regulator
(RRFPR). When finished, disconnect the tool and reconnect the stock fuel
line. The adaptor installs inline between the OEM fuel rail and the R&D
RRFPR via the OEM connectors for easy connect and disconnect. The R&D
Tool works on both Yamaha and Kawasaki fuel systems. Installation time is
only 2 minutes. Liquid filled fuel pressure gauge sold separately.
