  • Fuel gauge

    Although the car is SORN for the winter and tucked up in the garage... One of the jobs on the 'list of jobs to do' is to fix the fuel gauge.. It works - but is only accurate to the 2nd half of the dial. If I go under 'half full' then I run out of petrol - as happened twice this summer. So I always carry a 5lt canister with me now.
    My Dad can't remember what fuel tank it has (he thinks it might have been from a Fiesta but isn't sure). For LWB Roadters built of the 2001/2002 era - what options were there for fuel tanks? Were only certain types used from certain donor cars - or was it more like 'make it fit' from a variety of smaller cars? I don't have pictures of the tank atm but in a month or so I might get it up on blocks and get underneath. The dash instrument is a Smiths gauge & I suspect that it hasn't been calibrated to the fuel tank sender either properly - or at all - or perhaps it once was but something has over time, corrupted the electrical signal. For the time being I have taped over the '1st half of the gauge' so that if I can see the dial needle than I'm alright, if I can't - time to fill up! I'd appreciate some advice on tackling this one!

    Re: Fuel gauge

    If its a Marina based roadster the most likely tank will be from a Ford escort Mk2 van or estate hence the sender not being compatible with the gauge..

    One tweak is to wire in a resistor of about 16 ohms between the gauge and the tank sender and then the gauge will read lower,

      An alternative is to use one of these https://www.spiyda.com/magento/index...izard-mk3.html

      scott h suggested it on another thread and as I had a similar problem to you I bought one. Great bit of kit, albeit a bit fiddly to setup. However, bridges any sender/ gauge combination and has adjustment points to ensure it's accurate across the full range.

        Thanks for both suggestions, I think I like the Spiyda bit; I imagine it acts as a variable resistor with definitive 'empty' and 'full' readings which allows you to correct the current fitted gauge. Sounds good, added to the growing list of parts..

          I think it was Jez Cox who did a write up in Pitstop of his Marina/Ford hybrid fuel sender conversion.

                Cheap enough but: I don’t see a fuel pickup pipe, and will it work with a Morris Voltage stabiliser (a euphanism) that runs between 9-10 volts.

                The article I mentioned earlier is here.
