fuel gauge

[old-and-rusty]

If it`s getting worse, you could have a hole in the float in your tank. So it`s filling up with petrol, falling lower in the tank and giving you a lower reading.

Pull the pump out and test the gauge whilst moving the float.

Hi
First check the earth wires round the top of the pump housing. I had a simular problem a while ago, turned out to be back earth contact.

my wife's Silvia only goes up to 2/3rds. I checked the float and the earth wires. I think there may be a spot of corrosion on the feed wire but where I don't know. it is on the list for repair but has been for a while. I will get round to it eventually. I tried manually lifting the float right to the top and it still wouldn't go further than 2/3rds. I could try providing a new earth wire first to make sure that is not the problem as there has been a lot of Hammerite slapped round there in the past.

Mine only goes to 2/3rds full even when it full to the top which is'nt often, my mk1 did the same, tried the earth on mine made no difference
