The main intake gas line on my Nitro 912 Savage is leaking. Every time I put gas into the tank, a small amount of gas can be found in the well. I have tried to remove the filler cap assembly to remove and replace the intake line but this seems near impossible. Has anyone completed this project previously. There is little to no room to work on the inside end of the filler cap or I would simply replace the line with the cap in place.

Any help is greatly appreciated.
