VARIOUS POWERJECTION III VERSIONS
The Powerjection III is available in two different versions. The Throttle body
assembly part numbers 70020 (Satin Finish) & 70021 (Polished Finish)
come without any fuel system. These part numbers will require the user to
supply the following components:
• EFI Rated Fuel Pump • EFI Rated 10 micron Fuel Filter • Fuel Pressure Regulator • Fuel Pressure Gauge
These versions were designed for those who already have existing components or wish to supply their own components.
The second version part numbers 70026 (Satin Finish) & 70027 (Polish Finish) come with the above listed components as an "all inclusive" package for
those needing all the components.

All systems will require the use of a return fuel line. A return fuel line is a
separate fuel line that allows unused fuel to return back to the fuel tank. We
offer a return fuel line kit part number 70107 for use with the Powerjection
III systems. This kit includes 25-feet of -06AN stainless braided fuel line and
all necessary -06AN hose ends and fittings to plumb the fuel pump, fuel filter and to connect to the EFI system. Note that any of the Powerjection III
systems can be converted to a returnless setup by incorporating our 70035
FuelOnDemand Kit. This kit also provides many other features that extend the
70108
life of your electric pump and also lessen the pump noise at idle or low
speeds, particularly on very large pumps. We also offer our 70108 Fuel Line
Kit for use with returnless systems.
All Powerjection III systems are tested live in a test engine cell to ensure they are fully operational as part of the extensive quality control measures maintained throughout the entire build process of the Powerjection III
system. Butterflies are adjusted and the idle is set for you on a running engine. (Set for a SB engine - you may need some minor adjustment.)

16. Fuel Filter (70026/70027 Only)
We recommend the installation of a pre-filter to avoid damaging the
fuel pump in case you have foreign particles in the gas tank. Note that
most small filters sold for EFI systems will not work properly. We have
tested a number of common filters and they cause fuel cavitation and
erratic operation. We recommend the Professional Products #10210 or
#10211 Inline Filter.
Almost all EFI systems require a vented fuel tank. This system is no exception. The fuel tank MUST be vented and the use of a vented fuel cap WILL
NOT be sufficient. Minimum vent size should be 1/4-inch. This system also
requires a return fuel line from the throttle body unit back to the fuel tank.
(Unless you are also incorporating our FuelOnDemand kit) It is necessary to
install a vent and provisions for the return fuel line if these are not already
present. If these modifications need to be performed, remove the fuel tank
using the vehicles manufacturer's guidelines and have experienced personnel make the modifications. If any welding is performed on the tank it must
be fully flushed all gasoline and gasoline fumes.
The Powerjection III throttle body will fit the common square-bore intake
manifold that a Holley 4150 will fit. The linkage of the throttle body is the
same as a Holley 4150 so there should be no need to modify the linkage for
the accelerator if the vehicle is presently equipped with a Holley. Carburetor adapters can be purchased from speed shops to adapt your intake to the
4150 square bore. If you have a spread bore carburetor style manifold you
can utilize a Professional Products #52111 Manifold Adapter Plate Kit to
allow the Powerjection III to fit your manifold.
