I pretty sure I am going to go with a fuel cell in my car and was wondering if anyone is using one with a built-in sending unit running the factory fuel level gauge? They sell one that uses 0-90 ohms and a stock Honda uses 2-110 ohms. Also, what size is everyone using, this is going to be a street car so I was thinking about a 18"X18"X10" 12 gallon. Also, since most cells are made for a carbuorated/returnless fuel system, how should I go about installing a return line, and what should be done to vent the cell? Sorry for the rambling of questions. Any input is appreciated.
