Billet Fuel Pump Hat, 370z


The CJ Motorsports billet fuel pump hat is a rigid upgrade for the factory 370z fuel pump module. Made from thin plastic, the factory hat is a regular failure point. Our hat is machined from aluminum (6061-T6) for superior durability and reliability. The factory original stainless posts, once removed from the original hat, are secured to our hat with stainless wedge set screws that capture a barb on the tip of the post to ensure they will never pull out.

The included CJM 6-position electrical bulkhead kit features internal and external disconnects and supports up to 12AWG wiring. 14 crimp terminals are supplied (6 for pump wires, 8 for sensor swires). Our connector is rated to 40A, so no more melted fuel pump connectors when using high output fuel pumps. New stainless hardware to secure the hat to the fuel tank is supplied.

There are 3 6AN bulkhead ports for plumbing your fuel lines. The installation kit includes a swivel bulkhead with QD adapter for a PnP fuel pump hose connection, and 2 plugs for the unused ports. A new PTFE hose with clamps is supplied to connect the in-tank fuel filter outlet to the bottom of the bulkhead.

Technical Notes:

  • This product is a standalone upgrade, and can be integrated to any fuel system configuration.
  • No additional purchases are required to add this product to a stock fuel system.
  • Installer must be comfortable with wiring and crimping terminals to assemble connectors.

Installing with a NEW CJM return fuel system: No additional components are necessary. The supplied plumbing components (swivel bulkhead and PTFE hose) will instead be used for the return to the CJM regulator delete provided in the return fuel system. Use the fuel systems included fuel pump bulkhead and PTFE hose as you would with the factory plastic hat.

Installing to an EXISTING return fuel system: You may need the optional component for adapting the supplied PTFE hose to the regulator delete in your return kit. See below for details.


Regulator Delete Adapter: Some older CJM return fuel systems (or other brand RFS that included the CJM regulator delete) used a 3/8" barb adapter fitting for the regulator delete. In this scenario, a new 5/16" barb adapter for the regulator delete would be necessary to connect the provided PTFE hose for return fuel.
