INDUCTION SYSTEM
The Edelbrock Pro-Flo XT system delivers fuel and air to the engine via the induction system consisting primarily of a manifold, 90mm air valve,
fuel rails, and fuel injectors. The induction system is fully assembled, tested, seal checked, and flowed at the factory and is as easy to install as a
manifold. DO NOT DISASSEMBLE any of these components during installation.
INTAKE MANIFOLD
The new Edelbrock Pro-Flo XT manifold has been designed specifically
for electronic fuel injection applications.
90mm THROTTLE BODY
The Pro-Flo XT system uses a throttle body with 90mm air valve. The
air valve can flow up to 1000 cfm at 1.5" of mercury when wide open.
FUEL INJECTORS
The Pro-Flo XT #3527 & #3528
systems use high impedance pintle-
type fuel injectors. The injectors
are capable of flowing 29 lbs./hr. at
50 psi. The injectors mount directly
onto the manifold, one at each port,
for fuel delivery that is precisely
controlled and instantaneously
injected.
FUEL RAILS
The extruded aluminum rail assembly routes the high pressure fuel to
the injectors. Aluminum rails have an advantage over soft rails both in
terms of style and safety.
ASSEMBLING PRO-CLASSIC HOSE
Step One:
Cut hose to length,
as straight and square as
possible, with razor blade-type
hose cutter or shears.
Step Two:
Unscrew socket
from hose end. Push hose into
socket, turning counter-
clockwise, until hose is seated
against step in socket. Make
sure rubber part of hose does not
protrude into socket threads.
Step Three:
Apply Russell
assembly lube to threads on
nipple assembly and in socket.
Insert nipple into socket/hose
and start threads by hand
(clockwise).
Step Four:
Hold socket/hose in
vise. Turn nipple with wrench
until there is less than 1/16"
between nipple hex and socket.
Repeat Steps 1-3 for other end of
hose. Then, flush hose assembly
with solvent or soapy water and
blow clean with compressed air or
let air dry.
