Hello, the fuel pump sits outside on my Hayabusa Gen 1. As many people know, this often causes problems. This year there are already 2x .Pump,Filter everything renews but I trust this misconstruction nuicht more. I came up with the idea to take an external pump and a petrol pressure regulator with return connection.In GB such a thing is sold completely but around 800 Euro incl. taxes.Almost as expensive as complete pump housing Hayabusa. My question for installation: Pump at the tank inlet next-output pump to the pressure regulator from there to the injection strip and the return of the pressure regulator to the tank. Would that be so correct or thinking error from my side? The pressure regulator I wanted to take has 3 connections plus vacuum. 1x input,1x to the injection strip and connection return. Gruss Thomas
