Randy, for what its worth, I have separate tanks/fillers & a change-over valve - never had a problem filling up 2 tanks as the car is so low that the petrol station hose is easily taken around the front from one side to the other (also provides a talking point for the gawkers, etc) !!

If you join the 2 tanks & want to fill from one side, you will need at least a 1" crossover pipe (as Russ mentioned). IMHO, the less fuel piping (and the smaller it is) is a safer prospect - the thought of a 1" or 2" crossover pipe at the bottom of the tanks letting go is not a nice thought !

I have a separate fuel sender & gauge for each tank - given the long / shallow tanks, these are rudimentary at best : you get a bit of an idea of what's there on the level, but most of the time they act as inclinometers ! If they read full, you are going up / if they read empty, you are going down !!

Kind Regards,
