This plumbing kits include everything required to plumb the fuel system between the Radium pump hanger and the fuel rail. This kit is NOT designed for the stock fuel rail.
The kit includes -8AN (1/2″) feed hose that runs from the fuel pump hanger through the provided fuel filter. A -8AN 90 degree PuskLok hose end is included for connecting to an -8AN male aftermarket fuel rail fitting (not included). A -6AN (3/8″) fuel hose runs from the FPR (not included) to the fuel pump hanger return port. A -6AN 90 degree PuskLok hose end is included for connecting to an -6AN male aftermarket FPR fitting (not included). The fuel lines run though billet aluminum fuel brake line retainers. The fuel lines clear the OEM fuel pump cover and do not require any cutting or drilling to get them past the fuel tank. The feed and/or return hose can be easily modified for installation of an in-line flex fuel sensor.
The included Radium Engineering fuel filter mounts in the stock filter location using a specifically designed Nissan bolt-on billet mount. Depending on the kit selected (-03,-05), the fuel filter will be assembled with a choice of different elements. The -05 version is most popular because it meets filtration requirements set forth by Bosch Motorsports and works well with E85.
