My fuel gauge has always read 1/4 tank low
Tested the gauge by earthing out the wire on the sender and it goes to full
So i guess the sender is out
Just wondering if maybe the wire arm that holds the float might be bent causing the error
Just asking if anyone has had similar issues
Before i go by a new sender

Is your temperature gauge accurate?

Float could have a hole in it.

I would test the fuel tank sender ohms readings first.

I think its around 260 ohms to 20 ohms??? Will have to go through my files to confirm.

With an empty tank you should be able to raise the float with a wire or coat hanger.

There is an example here. http://www.gomog.com/allmorgan/FuelSend ... ching2.pdf

OK went to test the sender and i shone a torch in the hole
Very nice clean tank i must say
Lifted the float to see it half full of petrol
Anyway i ordered a new float and seal
And i tested the sender and it seemed to be OK ohms wise

Whilst your checking things, check that you have 10v going to the sender and not 12v.

My voltage stabiliser (found behind speedo) was faulty and sent 12v to the fuel gauge sender, causing it to read a quarter of a tank when empty.

fitted new float and put 1/2 a tank in and the gauge reads 1/2 tank
As i said the float was 1/4 full of petrol and have no idea how it got in there as i cant seem to get it out
