a bolt on with little hassle is what your asking for - then the EZ efi system sounds right for you - the eddy setup requires a laptop during inital fireup, and I dont know to what extent you need to get into the program, but the FAST Ez efi system is pretty much plug and play - thats a god fit for you it seems.

I'll let you know in a few weeks as I am in the process of the EZ efi kit right now.

I researched and got a fuel pump in the tank from rock valley - they convert a stamped steel tank to an efi, in tank setup.
