370z Stage 1 Fuel Return and Flex Fuel combo system

This kit is meant to bridge the gap between off the shelf flex fuel kits and off the shelf fuel return kits to serve as a do-it-all fuel system solution for your boosted 370z!

We've integrated tried and true components from CJM, Radium Engineering, Fuel-It!, and FLF race supply for a high quality fuel system that will perform as well as it looks. The configuration is a simple and compact design that works with factory fuel rails and the OEM fuel tank top hat. It comes partially assembled to make install a breeze.

Notes:

Flex Fuel Wiring:

Black: Ground: Unbolt most convenient chassis M6 bolt and reinstall with ground wire attached.

Red - 12V with Key on: Connect to tan or yellow wire on top right connector of BCM. Check for 12V with a meter to confirm.

White - 5V ECU signal wire: Pin 102 on ECU. This is in the smallest of the 3 ecu connectors. Cut the wire harness sheathing to expose the harness. With connector removed and visually looking into opening where the wires enter, pin 102 will be in the second column from the left, and the second wire from the front most row. Cut this wire and splice the white wire in so that the Flex Fuel analyzer can give the ECU the proper signal. Tuning will be required to select the CPC pressure sensor input as the flex fuel source. Remote tuning packages available HERE if you would like this to be configured through VPF.

The main fuel feed line will attach to the CJM fuel port with the pre installed 90* fitting and run towards the front of the vehicle to avoid heat from the exhaust. Ziptie the line to one of the radiator fan shroud spokes.

The oem Fuel line will remain in place and serve as the return line. When configuring your fuel lines, make sure the oem fuel barb on the under side of the top hat gets one of the supplied hoses to keep the return fuel aimed towards the basket OR feeding the OEM siphon and swirl jet if the pump is not configured to do so on the high pressure side.

The Supplied 6AN 90* bulkhead will require a small hole be drilled in the OEM fuel top hat. Care must be taken to only drill the hole big enough to

No fuel pump kit is supplied as there are already numerous options for these. However we are working on something in the near future to address the complications of installing the common walbro 450/525 in the OEM housing.
