    My 2006 LR3 is leaking gas next to the exhaust catalyctic converter on the right side... is this a big fix? Is it a DIY. Suggestions please.

    You would have to probably remove the skid plate at a minimum to determine where the leak is coming from. Hopefully you have the mythical BC vehicle with no rust, then that is fairly straight forward. Raise to off road height, then get a floor jack and some blocks of wood to help lower it down. Then look around for the leak.

    Thanks Greg... the leak seems to come from the rear right side of the engine and comes from a hose going into exhaust catalytic.

    What engine do you have? I don't think there are any hoses running into the cats.
    This is the 4.4 V8

    the 4.0 V6 is similar.

    Number 3 is the cat. 7 Silencer - Front, 8 - Silencer - Centre, 9 - Silencer - Rear.


    Here is the fuel system for 4.4 v8, again v6 is similar:

    10 - Pipe - Fuel pump to engine (feed)
    11 - Pipe - EVAP purge valve to charcoal canister

    I would think if it was 10 leaking it would be a very bad leak as the line is high pressure (65.25 lb/in²). Given it's leaking on your cat there is pretty good chance of a fire, so I wouldn't drive it until you get it fixed. So I would think it's either one of those lines, possibly it's only leaking at the connection to fuel rail. Take off the engine cover and get a light and a mirror and have look at the back of the engine.
