Fuel gauge on XK150
#1
![Default](/forum/images/icons/icon1.gif)
Hi
The fuel gauge on my XK150 always jumps to full when I switch on and the red fuel low warning light also comes on. I tend to ignore these as I dip the tank and always carry a spare can in the boot….but it is something I want to correct.
Can anybody offer suggestions?
Thanks for your inputs
Cheers
Mike

I don't have an XK series sports car, but I did notice your car as 1957 build.
That was at the same time as MK1 sedans were manufactured i.e. 1955 to 1959.
i have owned about 5 of these MK1cars and a similar number of MK2s.
One Mk1 I acquired had a similar problem to yours with the fuel gauge going to full with the low fuel warning light on.
It turned out that somebody had put a MK2 fuel transmitter in place of the MK1.
Although they look similar the MK2 fuel gauge operating system is quite different to the MK1.
I would start by disconnecting the fuel gauge transmitter and ensuring the gauge sits at zero and the light is out with power on.
Then try to identify what transmitter is actually in your car.

I have had a look at the fuel gauge transmitter as displayed in the SNG Barrat parts system.
It is different to the MK1/2 system where the transmitter is on top of the tank.
Yours is on the side of the tank.
Lets not rush into this fault finding.
Did you disconnect the wires to the transmitter as the first step?
