The problem is for many fuel injected vehicles, they get fuel pressure off a common fuel rail maintained at X pressure. Any fuel not used gets returned back to tank from pressure regulator return line (which ends up being most of the fuel ).
So its hard to heat fuel after rail (between injector and fuel rail ) as there no room with injector mounted right into rail .
Honda does not use return line on fuel rail, they have pump and fuel regulator in gas tank and run constant fuel pressure over the whole load . So with only 1 fuel line to rail I could see this being warmed up a bit (water warmer off heater core line) but not sure how much this would help with modern injectors as noted in above posts .
