The Chase Bays AN Fuel Line Kit for KA24DE / SR20DET Nissan 240sx / Silvia is designed for enthusiasts who want to upgrade their fuel lines and fuel filter with high end components and stealthy design. If applicable, this allows you to adapt an aftermarket fuel rail or fuel pressure regulator (FPR) seamlessly. The kit is assembled with all black aluminum A.N. fittings and -6AN stainless steel reinforced hose with high heat nylon sheathing. We use the best components in the industry and we pressure test every line we assemble. We guarantee a leak free start up if this product is installed correctly.
This deletes a portion of the engine bay feed hard line and replaces the filter. In factory form its ugly, bulky, and routed inefficiently. Often in the way of other components. You will cut the feed hard line back about 6" inches to match the return hard line length. This provides a nice tidy look and gives the filter a new mounting location. See photo below for visual reference.
There are many different needs out of fuel systems so we offer 2 main options for our Fuel Line Kits. Keeping the Stock FPR (CB-N-KASRF) and integrating an aftermarket external FPR (CB-N-KASR-FPR).
Stock FPR kit has 3 hoses. The feed line routes from the hard line to the inline fuel filter. The inline filter mounts directly to the frame rail on an existing threaded bolt hole and supplied rubber insulated clamp. From there it goes directly to the fuel rail inlet using different adapters per your entered specs. The return line is easy enough, attaching from the pressure regulator output to the hardline.
The Aftermarket FPR Kit changes the design to integrate the FPR and adds 3 adapters needed for the FPR to attach the lines to. The aftermarket FPR kit does not work with 2 port type, just the 3 port type. It mounts on the driver side shock tower just in front of the master cylinder (see photo below). It is a "dead head" setup which means the FPR is pre-fuel rail. Many kits have the FPR after the fuel rail which makes for 1 extra fuel line and more engine bay clutter. Chase Bays specializes in fixing clutter. The dead head setup is what the 3 port FPR’s were designed for and is common practice in the motorsport world.
