Risking a bite on the bum from the forum police here , but what sort of money are you able to stretch to ? and do you mean the standard round fuel gauge with a needle type ?
I've got a new mechanical fuel gauge for a tank depth of about 270mm - is this of any help? Simple and no electricity required! Direct reading dial from Full to Empty.
Thanks guys for your suggestions, unfortunatly I only checked tonight and the one on ebay, (Thanks Roger) was gone and it is exactly what I was after, and a good price too, which is the sum I was looking at paying, only thing, it dident say if it was Euro resistance or US.
I will keep a closer look out.
