    Advice on best way to install second gas line for auxiliary engine.-gctid363932

    I have a 10 horse Honda on the back of my boat. Currently it is connected to a small tank which sits out on the swim grid. I would like to add a gas line connection to it from the main tank. If there has been a discussion on the best way to do this already could someone please point me to the thread, I did a search but did not find anything...

    I wondering where the t should be added? Additional valves... Best practices...

    Thanks

    I assume both motors need the same type fuel. If you have a spin on filter for your main engine installed just run a fitting and new hose off the housing. Most have capability for 2 fuel lines.

    If not, many gas tanks have either a second pickup already installed or a blank off for one to be installed. Of course then you need to add an inline filter.

      Some have also added a check valve in the new line as well so the main engine doesn't suck the fuel out of the auxiliary line and engine.

        +1If you don't have the fuel filter now, the need for the second line to your auxiliary is a good reason to add it. As Fish-a-Palooza advised, the second output is ideal because it will help ensure you have rated fittings there.

          Good point. I was going to mention that this is usually unnecessary.

            The tank in my 1998 2052 Trophy is fitted with two (2) fuel pick-up's. Use one for the big engine and the other for the kicker.

            I steered away from using the second outlet on the existing fuel seperator because if the filter fills with water, both engines will not run. If they are on separate filters, I figured the chances of both filling with water at the same time were a lot lower.
