Fuel setups

[Ph1 Tom]

My current car runs a return and a pressure regulator in the rail. The new one has no return or regulator.

Which is best?!

Horses for courses mate. I'd remove the return system off your ph1 though!!

 

[Ph1 Tom]

No difference? Yeah I will mate

 

[NorthloopCup]

In terms of the power output that your engines are making there's no real advantage that I can see from either setup tbh mate. The return line system just makes it easier to install a swirl pot if and when the time comes. The return line system comes into its own on fuel hungry boost buses as it allows you to alter fuel pressure easier (reg on rail), but the single line system would need to be swapped over as it's harder to adjust the pressure (in tank with the pump).

Thread resurrection!

Does the phase 2 pump regulate the pressure mechanically? i.e its pre-set within the pump and receives no information from the ecu?

Therefor you can run a phase 2 pump in a phase 1? (with correct rail etc.)

I'm led to believe that there's a in tank pressure regulator on the ph2 so that's how the fuel pressure is regulated.

Yes you could run a ph2 pump in a ph1.

There is indeed a pressure regulator on the sender unit in the Ph2 tank.

Excellent. I'll be 'modifying' mine. Lol! :up:

 

[Ph1 Tom]

Standard is 3.5 bar on the Ph2. 4 bar will be more than enough.

Do we have wideband lambda's?

 

[Dan@SJM]

Not as standard.

Ah ok! Also keep in mind that raising the pressure will put some extra strain on the fuel pump, so make sure its healthy
