FUEL PUMP ASSEMBLY

Assemble the fuel pump assembly per

FUEL PUMP RELAY INSTALLATION

Find a suitable location on the driver’s side
of the vehicle. (See Fig. 7-b.) Locate the
fuel pump relay as close to the battery and
fuse box as possible.The location of the
relay shown is just for reference as some
vehicles may be different. Generally you
want the relay to be as close to the battery
as possible.

Attach the wire coming from the #30 termi-
nal on the relay to the power distribution
box on the driver’s side of the vehicle using
a 3/8" ring terminal.

Attach the #86 terminal to the #58 factory
fuel pump relay in the power distribution
box. (See Fig. 7-c.) Attach the #86 terminal
from the supplied relay to the #87 terminal
of the factory fuel pump relay. This will be
the trigger wire that will turn the additional
fuel pump relay on.

Using a spring lock tool, disconnect the fuel
line located just in front of the transmission
cross member.

Attach the fuel pump inlet hose to the steel
fuel line coming from the fuel tank using the
90° fitting provided in the assembly.

Attach the fuel line that is coming from the
fuel pressure regulator to the flex line that
you disconneced from the steel hard line.

Take care in routing the fuel lines. Keep
them away from sharp, hot or moving parts.

When finished installing the fuel pump
relay, cycle the ignition several times and
check for fuel leaks.

Attach the #87 terminal wire of the addition-
al fuel pump relay to the positive terminal of
the fuel pump. Carefully route the wire
down the firewall to the fuel pump. Be sure
to keep the wires away from hot, sharp or
moving parts.
