MOUNTING PROCEDURE

Step 1

Mount the pump as close as possible to the fuel tank in a

well ventilated area with minimal exposure to road debris.

Avoid exposing the pump and fuel lines to moving parts

and hot surfaces, such as the exhaust system.

The pump should be mounted at tank level or below.

NOTE: Increasing distance between pump and tank will

decrease pump efficiency.

Step 2

Using the pump mounting bracket as a template, locate

mounting holes on a solid member, such as the vehicle

chassis. Drill clearance holes for 5/16" bolts. NOTE: To

ensure against a potential fire hazard from pump

flooding, mount the pump in a vertical position with

the motor on top.

See Figure 1.

Step 3

To prolong pump life and efficiency, a high volume fuel filter

(Part No. 3500) must be installed between the pump and

fuel tank. Connect #8 AN fuel lines as shown in Figure 2 for

Standard Regulator or #10 AN lines as shown in Figure 3

for Return (Bypass) Style Regulator.

Step 4

Be sure to install one of the Mallory High Volume Fuel

Pressure Regulators between the pump and carburetor.

For maximum efficiency, mount the pressure regulator

as close as possible to the carburetor. See instructions

packaged with the pressure regulator. Make sure all

fittings are tight so that air cannot enter the system.
