On MFI metering unit's where the fuel return is,There's a multi plug attached to the fuel pressure switch,Well you can adjust the fuel there apparantly you remove the sensor and un screw and then adjust the fuel pressure with an allan key by the look's it?

Now which way is more fuel and which way is less?

Anti clock i would have thought is more fuel as your removing the screw,

And clock wise less as your pushing the screw in further,

BTW this is not for me, It's a mate who think's he aint getting enough fuel,

Any idea's anyone

 

I'm not touching it lol He can touch it if he want's i have passed on the warning's LOL.
