The only real benefit I can see to heating your fuel is that it will keep combustion temps up... i.e. the fuel won't be leeching as much heat from the combustion chamber as it is sprayed in, resulting in a hotter combustion chamber, which technically is more efficient.

By the way, the restrictive nature of OEM intakes on most cars, coupled with the fact that it has to travel through a heated throttle body, into a hot intake, means that it is in fact heated, extensively, from the initial temp of intake.
