Hi all - We previewed this prior to summer but got delayed releasing these kits. Better late than never!If you've been looking for a complete engine-side fuel system upgrade for your FD RX7 / 13B-REW? Look no further!

We are offering these complete kits with Radium components, custom made AN hardline to connect the primary and secondary rail, and 6an feed/return lines. The hardline allows for a cleaner install and avoids having looped fuel lines to connect the rails. The PTFE-lined stainless braided feed and return come with the appropriate AN barb fitting to allow install with the OEM feed and return lines. For the secondary rail, there is the option to use the OEM Fuel Sensor Port or No OEM Fuel Sensor Port (options selected on website).

We have two versions of this kit - one for the OEM LIM and one for the Xcessive LIM. The injector combinations available are below. We are offering DeatchWerks and Injector Dynamics injectors in various sizes.

Looks like a very complete, thorough kit. Nice job, as usual.

 

With this kit, do you need to retain the stock diffusers?
