Barry Grant BG 400 Installation And Tuning Instructions

BG 400
Fuel System
#170001
You have bought the BG400 - the ultimate in
state-of-the-art electric fuel system. It will
provide a fuel flow of 400 gallons per hour. This
system is different from the one you are accus-
tomed to, so please READ THE INSTRUC-
TIONS THOROUGHLY and follow them to
insure maximum performance from your BG
Fuel System. THIS PUMP IS DESIGNED
FOR COMPETITION USE ONLY. ANY
USAGE IN STREET DRIVEN VEHICLES IS
STRICTLY PROHIBITED. A list of related
components and accessories is included on the
back page of these instructions.
PUMP INSTALLATION
Mounting
The best location for mounting your BG400 Fuel
System in the vehicle is as close to the fuel tank
as possible. The fuel pump inlet should be level
or below the fuel pickups if at all possible.
THE PUMP SHOULD NEVER BE
MOUNTED IN THE DRIVER'S
COMPARTMENT OR NEAR ANY HOT
ENGINE COMPONENTS.
It should be mounted on a solid member, such as
a chassis, in a vertical position; motor on top. A
mounting bracket comes with the fuel pump. If
desired, an optional band clamp kit (part number
170030) is available. Do not allow the motor
housing to touch any metal parts on the vehicle.
This will affect the motor and pump perfor-
mance.
The fuel pump should be fed by a single #12 or
equivalent line from the tank. This may require
rework of your existing fuel cell. A BG5000
(part number 170018) fuel filter should be in-
stalled before the pump as it will prolong pump
life and does not restrict flow. Plumbing kit
INSTALLATION AND TUNING INSTRUCTIONS
Inlet
number 152387 has all the necessary parts includ-
ing a pump to filter adapter fitting (part number
140019).
The outlet side of the pump, going to the regula-
tor, should be a single #10 or equivalent line.
Plumbing kit number 150287 has all the necessary
parts from the pump outlet to the BG Regulator
inlet.
The return line should be fed with a single #8 or
1/2" line. Plumbing kit number 150187 is avail-
able for this application. The return should expel
the bypassed fuel into the liquid rather than into
the air space of the fuel cell. This will prevent
aeration of the fuel. All fuel tanks and cells
should have fuel cell foam installed to prevent
fuel slosh.
WARNING: DO NOT BLOCK THE RE-
TURN, VENT, OR PUMP FEED. MAKE
SURE THAT THE SYSTEM IS LEAK FREE
AT ALL CONNECTIONS...YOUR SAFETY
DEPENDS ON IT!
BEFORE MAKING ELECTRICAL CON-
NECTIONS, DISCONNECT THE POSITIVE
TERMINAL FROM THE BATTERY.
Your BG400 Fuel system should be connected to
a fully charged 12 or 16 volt battery. A fuel
pump, like any other electrical accessory, will
only perform at its best when given adequate
voltage. The black wire is a ground (-) and the
remaining wire is a switched hot lead from a 12 or
16 volt source. If wired incorrectly, the pump will
