I have recently successfully tackled the restoration of fuel gauges on both my FL5 and FL6 lamps. Having read a number of threads on here about the topic and the difficulty in obtaining replacements and understanding the frustration of a gauge not working, I have produced the PDF file as an illustrated guide to how I tackled the issue. I am sure that the are other ways but this is my way and the method I will employ should I need to restore another. Of course I am open to suggestions as to how I could improve or simplify the process and I am happy to answer any questions which you may have. Finally, do let us know if you decide to try it.
