    Fuel Rail??

    What type of fitting attaches to the backend of the fuel rail? I know it is not used on the RXP's but what 4-Tec uses this?

    Do you have a rail you can look over real close?
    See if there are any identifying marks from a manufacturer.
    It COULD quote possibly be used a 3 cylinder automobile engine
    in which there could quite posssibly be a drop in reg available.
    It doesnt have to be a 3 cylinder engine as teh reg will not matter cylinder wise.
    I guarantee there is a drop in reg,I would say for an import car.

    the rail has been used in the Ski Doo line for years, it is for a fuel regulator and R&D has a kit coming out that uses the stock fuel rail and regulator instead of these $300 pieces we have out now. It was in a article i read months ago.

    Yes there are many drop in regulators available that are already 1:1 ratios. Almost all Bosch OEM's have them IE; Audi, Porsche, VW, etc.. There is a large clip that holds it in. Depending on what they are for they are usually 3, 3.2, 3.5bar etc.. and they are non adjustable. If anyone has a HydroSpace, it has one, not sure if it is the drop in for a 4tech rail, but that is the style. The block off you see in the attached photo was made for an Audi S4 2.7 Twin Turbo rail, and it fit the 4tech rail, so it is pretty safe to say the Audi Regulator would fit the 4 tech rail.
