...and why use those at 4bar? 4bar FPR's are not recommended unless you have a decent pump...

mmm...the tuning shop installed it. my car almost 2 year with 4bar no problems
thnx for the link :icon_thumright:
so I better use 380cc with 3 bar?

4bar taxes old pumps big time... you won't know you have issues unless you have an AFR gauge fitted and can see the AFR go lean or the engine stops from a melted piston...

Worth getting the fuel pressure checked or AFR at least see where it is... on AGU's most peeps use 440cc greens as they suit the ME3.8 injector drivers better...

3bar will be nicer on the fuel pump and no real need for 4bar if right injectors used tbh...

Prawn recently upgraded his intank using a pump from Bill... 4bar pump, nice and fresh..

Not sure if its those or the fatter ones... tbh those look like copies (especially as they are cheap)... there are a lot of chinese copy bosch greens about... genuine ones look like this...
