  • Question

    Is it possible to use the factory fuel line from the fuel tank installing only the filters and fuel pump near the fuel tank or do I have to use a new fuel line. Return line must be new, that´s clear, because there was no return line before. Ford Torino GT Fastback 289cui. V8 1968. Thx.

    By Joerg B. on March 10, 2018

    Answer
    That would largely depended on the diameter of your existing fuel line. While it can be done you will want to inspect the entire line for any damage. We recommend a minimum feed size of 3/8''s.

    Will this product work on a Volvo Pental 3.0 boat motor that has a Holley 2 barrel marine carb?

    By Julio G. on March 19, 2018

    Answer
    While it may function well on the engine, the product is not currently coast guard certified. Additionally there is no provision in your exhaust system for the oxygen sensor, which means you would be required to tune the system in open loop.
