Fuel Sender
Hi ive got a random fuel sender supplied by the kit manufacturer but not supplied with a gauge probably because the owners always want something
different but can any gauge be used with any sender?
Cheers

In my experience - no  The gauge and sender should be a `matched` pair - for instance an Escort gauge wont read right with a siera sender .
Its cuz I is blond , innit

^ unless either the gauge or sender can be calibrated in some way?
i actually haven't got a clue. i actually don't understand fuel senders at all. i don't get how you can have all that electricery in
a fuel tank and its ok

From the notes on my Acewell unit, fuel senders come in 100/ 250/ 500 Ohm ratings. IIRC VW campers come in 60 Ohm, but you can put a resistor in
series to make them work.
I guess putting in on a multimeter and seeing what the range is will give you an idea of the appropriate gauge (if you can get a matched one).

You could always make your own gauge like i have. i made the circuit from this website:

i have 8x led's above my R1 clocks that light up depending on the level of the fuel.. simple circuit, but it works really well

I'm sure the fuel level sender MNR supply is a racetech one, just buy one of their fuel gauges and it will work properly. I have this on mine
and it works very well.

Cheers for the response and damn the answer i hoped for was yes
Davey D that looks really cool but i dont think my dad will go for it as he really fancies the VDO gauges and its a shared build.
Probaly best if i call MNR or just try the VDO gauge.

The sender is a coiled wire wound onto a former over which a contact slides - i.e. a variable resistor but the resistance can vary hence
incompatability issues.
Fitting a resistor may help it work better with a gauge but it will not be accurate.
The current passing though the wire is quite smal so unlikley to cause sparks; even so, air/fuel needs to be in a specific ratio for combustion -
read explosion - to occur. The air will be forced out of the tank by petrol vapour.
Anyone who has ever had to call the AA out to start a car will realise how hard it is to ignite petrol.
