Gen III+ In-Tank Fuel Pump for
Jeep CJ Universals, 1972-1986

The Jeep conversion industry has seen various evolutions of fuel system modifications to accomodate modern fuel injection engines, including the installation of external fuel pumps and the installation of various variable pressure regulator systems. None of these methods are as simple, cost effective or desirable as this method.

The Fuel Kit
This kit is designed specifically for 1972-1986 CJ Jeeps and utilizes the factory Jeep fuel tank.

Novak’s Gen III+ fuel pump kit will cleanly upgrade the original Jeep fuel sender to an in-tank pump assembly that provides the higher, ~58 PSI pressures required by GM Gen. III+ engines.

Options:
Option I: With Pressure Regulator
Included in this kit is a pressure regulator / filter combo that will supply ~58 psi to the fuel injection rails through a return-less supply line. This is for Gen. III+ engines that require a regulator external to the GM fuel rail.

Option II: Without Pressure Regulator
Identical to the above kit, except the regulator is not included. This kit is for Gen. III engines that already have the factory regulator integrated into the fuel rail, typically many 1997-2002 GM LS / Vortec series engines. You will notice the presence of a diaphram style regulator and its associated return line, in addition to the always-present supply line. Check your engine for applicability.

This is an example of one style of regulator on an LS style engine. These earlier style fuel rails that feature their own regulator will always have a supply line and return line.

Installation
Installation requires that the fuel tank be lowered (and preferably nearly empty) and that this replacement fuel module replace the factory version.

Any person or shop working on any factory or conversion vehicle fuel system must consider that any open flame or electrical spark or tool spark in the proximity to fuel and especially fuel vapors can cause massive damage to life, health and property. Improper electrical connections can spark, overheat and ignite fuels and their vapors. If the installer is not qualified to work on a vehicle fuel system, they should seek the consulting and installation services of someone who is competent in this area.
