Customer Questions

Question:

What are the fiber washers used for in this kit? - Ryan

Answer:

Hey Ryan, those press into the corresponding sockets in the rails themselves, and act as thermal insulators between the rails and the lower intake manifold.

Question:

would this kit be a direct fit for my 1990 300zx? - Aldo

Answer:

Hey Aldo, you will need to splice in the connectors, clearance the plenum above Injector #1, and tune the ECU if the injector flow rate is different from stock. After that it does fit the 1990.

Question:

If I purchase this kit with the 370cc injectors, what brand of injectors will it come with? - Matt

Answer:

Hey Matt, it would come with AUS injectors.

Reviews

Rated 4/5 based on 1 customer reviews

Installation was easy. Some tips: Hose location and configuration just like in the photo of the product (If trying to assemble in a stock config). Top-left of the photo is front of vehicle. The barbed SS hoses come up and over the plenum but under the balance tube. Some manipulation of the dampener pip makes it a bit easier to get to work. Install the connecting hose before install of the rails. 5/16 hose came with 1/4 barbs on the lines. This made no sense as the image is 5/16 barbs.

Description

The CZP High Performance Fuel Rails are precision CNC machined for perfect fit and finish. These have superior flow characteristics compared to the stock fuel rail and are ideal for high horsepower builds.

  • Eliminates the need for an adapter kit, accepts new-style injectors and installs in an old-style lower intake manifold.
  • Thermally isolates the fuel rail from the lower intake manifold.
  • Utilizes AN fittings for the "cross-over" tube as well as the inlets and outlets. Also uses O-Rings as a "second barrier" to prevent leaks.
  • Can be used in a parallel or serial (like stock) configuration. Included fuel lines are for a serial configuration.
  • Anodized black for a clean look and long-lasting protection.

Note: If installed with an old-style upper plenum, you will need to grind away a small amount of casting above the #1 injector for the connector to clear.

This set also includes the following items, giving you everything you need to install:

  • Stainless Steel Braided Lines
  • OEM Fuel Hose and Clamps
  • Injector Caps w/all Mounting Hardware
  • 6x AUS Fuel Injectors, color will depend based on size.
  • Optional New Style Injector Connector Pigtails
