Default Fuel Pump Mods for Lifted Tanks

I have a 2008 Nightster and I love the look of the lifted tank. I made my own lift brackets that raise it up by about 2". This has dropped my fuel range though down to right about 100 miles. I made it home on the last ride of 2018 with the plan of overhauling the bike. I wanted to drain the tank as much as possible and as I cruised down my block I couldn't really give throttle without a it sputtering. When I took the tank off though there is still a bit of gas in it. I haven't drained it yet and measured it though.
The manual doesn't show where the fuel is siphoned up by the fuel pump though. My guess is that there has to be a way to modify the intake so that you can make the pump draw up from the lowest part of the tank and make the most of the tank capacity. Anyone any familiar with the fuel pump assembly have any ideas?
Thanks!!



FYI: I currently have the top end off my bike and am rewiring through the frame like Kosmo did. I'm hoping to post and share my journey through that process on Youtube. So I hope to have something to give back soon.

Lifting the tank means you lost capacity....its not just an issue with the pickup location you've created a bubble of air in the top of the tank thats higher than the filler hole...
