Hi All,
Just want to know if anyone has done this. All the new cars over here are doing this and with great results. A friend just made 501kw in his turbo Gen3 with the same setup. This is how it goes.

Tank to pump -
Pump to rising rate fuel pressure reg -
Fuel pressure reg to line that runs up the back of car -
From line to 'T' peice and then into injector rails.
Thats it.

The injector rails are blocked off at one end and then all you have is a 4mm vacum line that runs from the back to front of the car to let the Pressure Reg when to start increasing pressure. This eliminates all the hassles with breather hoses and fuel return. I am thinking of setting my car up the same because it is so simple.
Any comments?

Yes it will work and the only disadvantage is that your fuel in the rails doesn't circulate contantly, thus radiated heat will be absorbed by the rails and your fuel will run hotter as its fed to the engine via the injectors.

Thats about the only disadvantage of not running a circulating fuel system with return line.
