We offer 3 different solutions to connect the 3.4L 5VZ-FE high pressure fuel rail to the existing fuel-injected vehicle’s high pressure fuel delivery system, the hard line on the RH side frame.
The ORS 3.4L High Pressure Fuel Hose Extension ( can be used to connect the OEM 5VZ high pressure fuel hose to the existing high pressure fuel line on the frame. This is a good solution for 3VZ-E vehicles where the OEM 5VZ-FE high pressure fuel hose is still in good condition.
We also offer a full replacement hose that will not require the use of the OEM 5VZ high pressure hose. This full hose connects directly to the fuel rail and directly to the existing fuel line on the RH side frame. This is a also a good solution for 3VZ-E vehicles.
Our third solution is for vehicles originally equipped with the 22R-E. Since the 22R-E’s fuel filter was block mounted, a fuel filter is also needed for this conversion. The ORS 3.4L High Pressure Fuel Hose w/ Filter is a great solution. It replaces the OEM 5VZ high pressure fuel hose. The ORS hose connects directly to the fuel rail and directly to the fuel line on the RH side frame. An inline fuel filter is installed in this hose. This 10 micron filter has an easily replaceable and cleanable filter element, and is well suited for this application.
