GENERAL INFORMATION
®
The COMP PUMP 70 Series Electric Fuel Pump is a low volume fuel
pump designed for automotive applications. The operating fuel pres-
sure is factory set at 5-6 PSI. A fuel pressure regulator is not used. We
recommend a 5/16" or larger fuel line with this fuel system.
When installing the fuel pump fittings, use a thread sealant compound
(you can find this at a hardware store) on the fitting threads. Do not
use Teflon tape. Teflon tape can get into the Gerotor and lock the
pump. Also, do not overtighten the fittings. This could damage the fuel
chamber.
The fuel pump output pressure can be slightly adjusted on the vehicle
using a fuel pressure gauge. To change the fuel pump output
pressure, release the jam nut and remove bypass plug. Clean the
bypass plug. Apply thread sealant compound to the bypass plug
threads. Install bypass plug. Turning the bypass plug clockwise
increases fuel pressure. Tighten the jam nut.
Be sure to install a suitable fuel filter (minimum 40 micron filtration)
between the fuel tank and the fuel pump. The Mallory COMP FILTER
®
Series Part Nos. 3140 is recommended. This prevents debris from
becoming wedged in the fuel pumps Gerotor and locking it.
MOUNTING PROCEDURE
Step 1
Mount the pump as close as possible to the fuel tank (at or below the
level of the fuel tank pickup) 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.
NOTE:
Increasing distance between the 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 holes for 5/
16" bolts. See Figure 1.
NOTE: To ensure against a potential fire
hazard from pump flooding, mount the pump in a vertical
position with the motor on top.
Step 3
Connect fuel lines as shown in Figure 2. If your fuel system requires a
fuel pressure regulator, proceed to the instructions with the fuel
pressure regulator.
