Cheers

You wouldnt happen to know which one i would need

Do you have a close-up picture of the gauge (or gauges)? For example, I'm using a couple of these gauges:-

s-l500.jpg


which requires a sender with resistance ranging from 20 ohms (full) to 260 ohms (empty), like this Triumph TR unit:-

s-l1600.jpg


The sender arm can bent bent and shortened to match the tank depth, providing overall travel remains the same. The Smiths gauges also need a 10v input from a Lucas voltage stabiliser or equivalent. They don't work properly on the variable 12 to 14 volts of a vehicle supply.

But you need to start with identifying the gauge, then you'll know the sender resistance range you need. Finally, this might help:

Hi Eddie this is the fuel gauge not much to go by

Looks like a Smiths "GT40 style" gauge, and would require a 20-220 ohms (or thereabouts) sender:-

Though it might be the voltage regulator which has failed, and these are often wired to provide the necessary 10V feed for fuel gauge and oil temp / water temp gauges (all three of these require 10V to read correctly).
