1 / 4 page COMP PUMP® SERIES 70 ELECTRIC FUEL PUMP PART NO. 4070 INSTALLATION INSTRUCTIONS ® FORM #1042 (REV. B) 8/00 NOTE: DO NOT RUN THIS PUMP WITHOUT FUEL (EXCEPT FOR BRIEF PERIODS WHILE PRIMING). SPECIFICATIONS Operating pressure: 56 PSI Fuel pump inlet/outlet thread sizes: 3/8" NPT Oil pressure switch rating: 5 AMP Fuel pump over current protection: 5 AMP fuse Fuel applications: Gasoline Service Parts PN 3146A Brush Kit PN 3164 Seal/Repair Kit, Gasoline PARTS INCLUDED IN THIS KIT 1 Electric Fuel Pump 2 Nuts, 5/16" 24 2 Bolts, Steel 5/16" 2 Washers, Steel 5/16" Flat 1 Splice Connector 1 Ring Terminal 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. 1 This product is covered under one or more of the following U.S. Patents: 5,007,806; 4,998,557; 5,111,793; 5,123,436; 5,186,147. |
