What You'll Learn
The Chase Bays Fuel Line Kit
It is assembled with black aluminium A.N. fittings and -6AN stainless steel reinforced hose with high-heat nylon sheathing. Chase Bays uses the best components in the industry and pressure-tests every line they assemble, guaranteeing a leak-free startup if installed correctly.
The kit replaces a portion of the engine bay feed hard line and the filter. In factory form, the fuel line is bulky and inefficiently routed, potentially hitting the downpipe. With the Chase Bays kit, you will cut the feed and return hard lines back by about 12 inches and route them over the trans to the LHD driver side.

Using a stock FPR or aftermarket FPR
The Chase Bays AN Fuel Line Kit for 1JZ or 2JZ-swapped Nissan 240SX/Silvia S13 is a popular choice for adapting fuel lines with high-end components and a sleek design. This kit offers two main options for fuel pressure regulator (FPR) types: the stock FPR (CB-N-2JZF) and the aftermarket external FPR (CB-N-2JZ-FPR).
The stock FPR kit includes two hoses. The feed line routes from the hard line to the inline fuel filter, which mounts directly to the fuel rail at the front of the engine using a 90-degree coupler and adapter. The return line connects from the pressure regulator output back to the hard line.
The aftermarket FPR kit, on the other hand, adds an extra fuel line and three adapters to integrate the FPR. It is important to note that this kit is only compatible with the 3-port type and will not work with the 2-port type. It is mounted on the driver's side shock tower, in front of the master cylinder, in a "dead head" setup, meaning the FPR is pre-fuel rail. This setup is common in the motorsport world and helps reduce engine bay clutter.
While the stock FPR kit offers a more straightforward installation process, the aftermarket FPR kit provides greater flexibility and the ability to customise your fuel system. It is worth noting that the $50 charge associated with the aftermarket FPR option covers the additional line, FPR adapter fittings, and FPR bracket, but not the FPR itself.
For those seeking an aftermarket FPR, the Sard Standard FPR has been a popular choice for Nissan S13 owners. It is rated up to 450whp, and users have praised its quality and compatibility with their vehicles. However, it is important to note that the kit does not include a gauge or fuel rail adapter, which may require additional purchases.

The dead head setup
The Chase Bays AN Fuel Line Kit for the Nissan 240sx S13 with a 2JZ engine swap offers two main options for the Fuel Pressure Regulator (FPR) setup: the Stock FPR (CB-N-2JZF) and the Aftermarket FPR (CB-N-2JZ-FPR). The Aftermarket FPR kit adds an additional fuel line and is a dead head setup, as the FPR is located before the fuel rail. This setup is designed for enthusiasts who want to adapt their fuel lines with high-end components and a stealthy design.
However, there are some considerations to keep in mind. At idle, the deadheaded fuel in the rail can collect heat, resulting in slightly higher fuel rail temperatures. Additionally, it is important to ensure that the FPR is mounted away from the heat of the engine bay, typically in the fender area, to maintain optimal fuel temperatures. Overall, the dead head setup is a popular choice for those seeking improved fuel temperature management and a more streamlined engine bay.

Using Russell Steel Male -AN to 1/2-20 Inverted Flare Female SAE Brake Adapter Fittings
If you are experiencing problems fitting a fuel line to your 2JZ S13, you may want to consider using a fuel line kit. Chase Bays offers a kit specifically designed for the 2JZ-swapped Nissan 240sx S13 that allows you to adapt an aftermarket fuel rail or fuel pressure regulator (FPR) seamlessly. This kit includes black aluminum A.N. fittings and a stainless steel reinforced hose with high-heat nylon sheathing.
Alternatively, you may want to look into using Russell Steel Male -AN to 1/2-20 Inverted Flare Female SAE Brake Adapter Fittings. These adapters are Endura-plated steel AN brake adapters that are ideal for operating conditions where additional corrosion protection is required. They feature a durable ultra-brite finish that resembles stainless steel but at a lower cost.
When converting your stock hard lines to AN, you will need to make a 37-degree flare twice. The Russell Steel Male -AN to 1/2-20 Inverted Flare Female SAE Brake Adapter Fittings can be used to convert your 5/16 hardline into -6 AN, potentially reducing the number of adapters you need and lowering your costs.
It is important to note that the Russell adapters have a thread size of 1/2-20 on a 5/16 tube nut. This is a specialty fitting, so finding images or descriptions online may be challenging. However, it can be a cost-effective solution for your fuel setup.

Using a top feed rail and an aftermarket regulator
If you're using a top feed rail and an aftermarket regulator, you'll need to go from the pump to the filter, then two feeds to the rail, then one outlet to the fuel pressure regulator (FPR) and back to the tank. The FPR isn't before the rail.
The Chase Bays AN Fuel Line Kit for 1JZ or 2JZ is a good option for adapting your fuel lines with high-end components and a sleek design. It includes all the necessary fittings and hoses, and they guarantee a leak-free startup if installed correctly.
