    Long range tanks

    Ok as some of you have long range tanks . I need to ask a question that may apare to be stupid.
    How does the tank get the feul to the engine. i.e does it refill the original tank via a pump , or do you have a switch to switch it across from tank to tank, or does it just feed from both at the same time.
    Plus do you have a feul gauge for the spare tank or do you guesstimate

    Cheers

    I have 160 litre tanks. One is 127 then other is 33 litres. They are joined top and bottom by several pipes so it acts as one tank. 1/3 of my range is done with the guage sitting on full.

    I have twin sill tanks in my rangie with a solenoid to select between tanks and a sender in each that is activated when that tank is selected.

    That sounds like a fantastic setup
    (only because I have the same).

    I have a 65L sill tank which has four lights to indicate full to empty. There is an electric pump to transfer into the main. If the pump fails then I just need to siphon the fuel. As it's a 65L tank as soon as the main tank's low-fuel light comes on I hit the switch and back to full.

    Long range tanks are a great investment, even if you aren't going to exceed your vehicle's range they give you a lot more touring flexibilty.

    This is how we have ended up doing ours
    The spare tank will fill up the normal tank when the normal tank is empty
    Thanks, just wanted to know if this was the done thing or a cowboy way or not.
    You have now put my mind at rest

    Toyota owners will tell you it's better to directly feed from both tanks. I disagree, as if you feed into the main you will can entirely drain the aux, whereas if you feed from both you can't drain one of them so you're wasting maybe 5L of fuel. And if the transfer pump fails, well draining the aux isn't difficult.

    Yeah that was my thought on draining from both tanks at the same time
