Does anyone know how to?

Another option would be to add an extra injector, again, how could that be done? (on a budget).

Thanks!

bigger injectors and a afc

The only problem is that I cant run anything that has to do with the stock ecu (because I have a german car, no one makes computers for my car).

So I am looking for a mechanical way of doing this, or adding a second pump (but how would I tune this? etc)

no way to run an fmu without a return line plain and simple. the fuel has to go somewhere right

How hard would it be to run a return line? I'm sure you've got several ports on the tank for the vapor lines/purge etc.

^ True, but how do I fabricate a return style fuel system?

I would have to drill the stock fuel rail for one, and what about all the sensors that controll the flow for the returnless fuel system? HMMM...

Honestly, I have no clue about all the details of how a returnless system works. If you're looking to turbo this thing properly, a standalone engine management system might be your best bet. If you wanna ghetto rig up some ---- that will boost 3 psi and run super rich because you don't want it to blow up, adding extra injectors to the intake is a better bet than an FMU on a returnless system.

custom fuel rail, regulator and a return line to the tank

jegs and summit even sell a return line diy kit.
