This last winter I installed Aux Fuel Tank in my Gl1800/Champion trike. It took some thought but the result is worth having.
I used a TourTank 8X14 with a vent in the cap and an outlet on the underside at the other end. I used the tank straps that came with the tank to mount to a modified rear fender on the Gl1800 and tied down the back of the tank to the bar that holds the shocks on the trike kit and the front to the plastic rear fender. I ran the main line 1" to the bottom of the main tank and a vent line from the cap 1/4" to the top of the tank by the orginal tank vent. I made sure that the cap on the tank was as tight as I could get it. It clears the rear end with plenty of space. Basically it works the same as the CSC but for about $250.00. The tank holds 3.5 gals. I can go about 300 miles and then I need gas. I have tested this.
My wife says it looks like a little pig stuffed under the seat.
I didn't have to modify the relays on the starter or under the seat.
I have been using it from about Febuary and it works without fail. It fills promptly when filling the main tank but it does take a little longer because you are adding another 3.5 Gals.
The big test is we are going to PEI this August. I don't expect any problems with the tank.
