Overview

The Fore Innovations F2i to F4i upgrade kit is designed to allow you to upgrade your existing F2i Fuel Regulator to an F4i model by replacing the bottom portion. This kit includes six screws to attach the top and bottom sections. The F4i offers an advantage by potentially eliminating the need for y-blocks, associated fittings, hose, and hose ends, leading to a faster, cleaner, and less expensive installation.
Show original supplier description
The Fore Innovations F2i to F4i upgrade kit provides a straightforward method to convert your F2i Fuel Regulator into an F4i model. This upgrade involves replacing the bottom section of the regulator and requires new fittings, which are available with various options such as AN-08 or AN-10 Male 90° low profile, or a 3/8 EFI female for a flex fuel sensor. The kit includes six screws for securing the top and bottom components. The primary benefit of upgrading to the F4i regulator lies in its design, which features four pressure ports. This can simplify installations by eliminating the need for multiple y-blocks and the associated plumbing. Consequently, this can result in a quicker, cleaner, and more cost-effective setup for your fuel system. Optional add-ons are available, including a filter plug for atmosphere reference and a 6mL tube of Loctite 567 thread sealant. The product is universally applicable to any electronic fuel injected engine with a return-style fuel system, whether it uses port or throttle body injection. Contact Fore Innovations for assistance with your specific installation.
