My fuel gauge has never read properly. It reads 'empty' OK but shows full when the tank is actually about half empty. The fuel tank is off a Mini Van with a BMC Mini Van sender sending a signal to a Smiths fuel gauge - probably aftermarket not OEM. Question is what capacity resistor should I put in line so that the full is calibrated properly to when the tank is actually at the top? (12v & neg earth) Cheers Maximus

can you not bend arm in such a way so it only reads half full at half full

Don't be silly... a resistor will alter the correct empty reading as well. In order of cost (I've seen you in the bar queue - you'll go for method 7... ;D) Method 1: Buy a fuel guage and sender you tightwad Method 2: Buy a sender to suit your guage Method 3: Buy a new guage to suit your sender Method 4: Advertise on the parts wanted area - maybe traderbob or his henchman have something in their pile of old instruments Method 5: Drill a hole in the top of the tank and cut a stick from a nearby bush. Method 6: Carry a can. Hope this helps

Method 1 'Ow Much' - I've got to buy a round soon now you know ! ;D Method 2 'Ow Much' Method 3 'Ow Much' Method 4 Anyone got a guage to suit a mini van fuel sender? Method 5 I know another member who uses this method to very good effect ! Ony run out of fuel 15 times now !! Still it will need calibrating therefore better employ the use of............ Method 6. Do that anyway due to the fantastic fuel economy I get (not!!) Cant bend the float or else it won't be actually empty when it shows as empty Will a resistor in line affect the extremes of one of the readings? Wont it cut the current/volts sent at the full end of the scale to bring it to the full marker & not try to wrap it round the stop post. But even if it cuts the current/volts at the 'empty' end there will be no current/volts anyway hence reading 'empty' Cheers Maximus
