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.
Installing with a return fuel system? You WILL need the optional Return Fuel Bulkhead. You might need the regulator delete adapter. Please see the option details below.
Return Fuel Bulkhead: If you have a return fuel system, you will need this option. The latest CJM Top Hats have threaded -6 ORB Ports, and the standard package only includes one compatible swivel bulkhead fitting. You will use that one for the return fuel, and you will need to add an additional swivel bulkhead for the fuel pump output line. The 8mm and 10mm option is describing the size of the hose barb on the bottom of the bulkhead. You need to choose the one that matches your fuel pump so that it fits with your existing in-tank fuel pump hose. Most 255-340lph pumps have a 5/16 (8mm) barb. Walbro 400, 450, and 520 Hellcat pumps have a 3/8 (10mm) barb.
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. This adapter is simple a 5/16 to 1/8 NPT hose barb. It is not the actual regulator delete fitting. Since 2018, our regulator deletes have built-in 5/16 hose barbs and do not need this.
