CJM Twin Pump, FD RX7

Features | Options | Images | Installation

The CJ Motorsports fuel pump hanger for the 93-95 RX7 is constructed from a billet aluminum flange with 3x -6AN bulkhead ports and pump holder brackets consisting of aluminum, stainless, and polyethylene. Bulkhead fittings are included, and there is an optional plug for using this mount with a single pump. A stainless steel mount for your original fuel level sensor is also provided in this assembly.

NOTE: This product is intended for fuel pumps of about 39mm diameter. This includes in-tank Walbro pumps, Aeromotive Stealth pumps, and some pumps from AEM and DW. We no longer support Bosch 044 pumps, or Denso pumps.

We have integrated our 6-position 10-14 gauge electrical bulkhead (and connectors) to safely and professionally provide power and ground for your pumps and factory fuel level sensor. There are also 2 fuel pump ground studs that can be used for projects that need to leave connector positions available for an additional sensor (such as the OEM low fuel switch).

The pumps are held by polyethylene brackets with internal Viton o-rings. These soft materials can help reduce noise.

Basic kits include the flange with connectors and crimp-on terminals, bulkhead fittings, pump holders, OEM level sensor mount, and stainless fasteners to secure the hanger to the fuel tank. The flange will re-use the factory Mazda fuel tank gasket.

Our installation kits provide convoluted PTFE hoses, hose ends, clamps, and fuel pump strainers that you will need to install your fuel pumps to the hanger. Installation kits also provide a return hose to guide the return fuel into the factory baffle area.
