Twin Cam Softail larger tank

First post, first question. My current bike - a keeper - is a 05 Fi Heritage. I have now started modifying the bike to make it mine. My last Harley was an EVO Heritage. One of the mods I did was to replace the tank with 6 gallon fat bobs. I would like to fit a same size or 7 gallon tank to this one. I could replace the injection with a carb and do the same as I did before, but I want to keep the injection system.
Do you know of a bolt on larger tank for the fuel injection or where I could get my tank enlarged.

Thanks,

Vic

Hey Vic

I was hoping you'd get an answer or two on this one.
I'd be interested to have the same myself.

Keep us posted on how you get on mate.

I am sure that there are others too. I have tried the same question on USA sites. I would have thought that by now there would have been such a beast or someone had stretched/enlarged a standard tank.......obviously not.
