Maintaining proper fuel pressure is an important factor in keeping an engine running strong, consistent, and healthy. Monitoring fuel pressure on a VQ35DE, VQ35HR, and VQ37VHR can be very difficult without the necessary tools that the Z1 Motorsports Fuel Port provides.FuelPort

The Z1 Fuel Port is 100% CAD Designed and machined from 6061-T6 billet aluminum. Available with an attractive black anodized finish with laser etched Z1 logo. A high quality Viton o-ring is included to form a reliable safe seal at the fuel rail.

Fuel System Innovation

Unlike many different style fuel ports available, the Z1 Motorsports fuel port is designed with 1/8-27 NPT and 1/8-28 BPST threads to fit a variety of gauges on the market. This port can be rotated a full 180 degrees for use with either NPT or BPST threads. (due to physical constraints of the engine, use of only one threaded port at a time is recommended) Pre-machined pilots can be found on both sides of the fuel port giving you the ability to machine additional threads if desired.

Engine Diagnostics

This port makes an excellent diagnostic tool, as it can be installed within minutes and allows the user to install a mechanical gauge for under hood fuel system diagnostics. Additionally, a Schrader valve can be installed for use with many different style fuel pressure testers used by diagnostic technicians. These are available using the options below.

Simplifying Nitrous

Most 'wet' nitrous kits for VQ motors include a simple fuel tap that requires the factory line be cut to plumb fuel for the nitrous system. This fuel port can be installed with no modifications to factory lines, making fuel plumbing simpler and safer. A fuel pressure switch can be installed here allowing the system to cut nitrous pressure if fuel pressure ever drops below a specified value for additional protection.
