GENERAL INFORMATION

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)

Series Part Nos. 3140 is recommended. This prevents debris from

becoming wedged in the fuel pump’s 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.
