22RE to 5VZ-FE High Pressure Hose Fuel Hose with Fuel Filter

Note: The original 22R-E or 3VZ-E fuel pump (in-tank) normally works well with the 5VZ engine and can be left in place. However, if forced induction is used, we recommend upgrading to a performance fuel pump. Trucks or 4Runners originally equipped with fuel injection have a fuel pump mounted inside the fuel tank and a high-pressure fuel line from the tank to the engine bay area.

Carbureted vehicles do not have a high-pressure system in place. In this case, we recommend installing a fuel tank and hard line from a similar-vintage vehicle that had the 22R-E or 3VZ-E. When not using a Toyota tank w/ internal fuel pump, we recommend installing a high-pressure fuel pump in the existing fuel tank/fuel cell. The fuel cools the fuel pump during operation, helping it last longer. Additionally, in-tank fuel pumps nearly eliminate the risk of ‘vapor lock’ in the fuel system. If an external (in-line) fuel pump is used, we recommend mounting it as close to the tank as possible and as low as safely possible.

• The original fuel supply line (high pressure hard line from fuel tank/pump) enters the engine bay on the RH-side frame rail (on fuel injected models).
• At this end of the line, there is either a male fitting (nut), a female fitting, or a female to female fitting (union) fastened to a male fitting. A female fitting or a union is necessary. If needed (male fitting only), this fitting can be found through Toyota or NWT, 571511. See pic #35

• Full Hose and Hose with Filter: Remove the original 3.4L high pressure fuel hose from the rear of the fuel rail and discard. This will require removing the bolt and clip fastening the engine harness to the rear of the engine, then moving the engine harness up and to the rear. Install the provided banjo adapter in place of the original hose fitting, at the rear of the RH fuel rail, using the provided gaskets and original banjo bolt. See pic #36

• Install the provided M-M adapter into the F fitting/union on the original fuel supply line. Note the orientation of the adapter, it is a compression fitting with different threads at each end. Tighten both adapters.
• Fuel Hose Extension: Install the remaining M-M adapter into the end of the existing 5VZ fuel hose. Note the orientation of the adapter, it is a compression fitting with different threads on either end. Tighten the adapter.
• Hose with Filter: Using the provided clamp, mount the fuel filter on the inner fender above the fuel supply line. Note filter orientation by the inscription on the filter. The shorter hose will be used between the frame supply line and filter, use this as a guide when mounting filter, see pic #37
• 
  
• 7th Injector-Ready Fuel Hose: The installation of this hose at the engine and fuel line is the same as the full hose. There is an extra section of hose that will route to the new 7th injector. The adapter on the 7th injector must be replaced with the provided Adapter. We recommend using thread tape on the threads into the new injector on the provided adapter. See pic #38
• 
  
• Route and install the new High Pressure Fuel Hose(s) between the adapters (and filter if applicable), tighten all fittings. See pic #39
• 
  
• Note: If a 5VZ fuel hose was previously installed and the 7th Injector kit is now being added to the engine: Install the provided hose section and adapter to the new 7th Injector. This hose section will now be spliced to the existing NWT fuel hose. Using the new hose length (and pic #38) as a guide, cut the existing hose and press the two ends of the existing hose onto the new 7th Injector section.
• Caution: This will only work with relatively new hose, in good condition. If using an older hose, we recommend a complete replacement.
