Checking here before I purchase

[Groenys 57]

I wanted to make sure I am buying the right tank and sending unit to relocate under the bed.

I go with the smaller tank to go between the frame rails so I can run a filler neck correct?

Then I can run this sending unit? the model TAN-GME http://www.tanksinc.com/index.cfm/pa...rod/prd276.htm

then ill need to run new fuel lines and a filler neck?
