im looking for a fuel guage and sender unit that will work with a tank filled with foam (i think it therefore needs to be tube type or similar) can anyone suggest a website to look at such items?
thanks

ETB Instruments do such an item, also Cairbont

Pay attention to electric output (Ohm) as there are quite a few standards...

thanks guys, now i just need to find out which code part will fit my tank and what type of tube i need!
