Abarth Posted September 7, 2017 Share Posted September 7, 2017 Upgraded the Puntos fuel system to a Walbro 255lt pump. It's the standard in tank pump which replaces the factory Bosch one. Everything is sweet but shit is it noisy. Was thinking is there a smaller capacity pump? The Punto is now making round 250hp so I would only need to run something like an Evo or Silvia fuel pump? Does anyone know if all these fuel pumps are the same size? Quote Link to comment Share on other sites More sharing options...
mjrstar Posted September 7, 2017 Share Posted September 7, 2017 Walbro gss342 is pretty well identical dimensionally to an evo pump. (And many other jap cars). If its noisey it might be a mounting issue (touching the bottom of the tank etc) or bad pump as you shouldn't get more than a very quiet wurr out of it.
