Regulator thing on fuel pump
Hey all, i'm putting a new fuel pump into my r32, my question relates to the thing that looks like a fuel pressure regulator that sits in the tank with the pump.
My car already had a Bosch 044 installed and this regulator thing was missing, i'm putting in a Walbro, what does this regulator do, and does it matter that i haven't got one???
Car never had any problems with the way it was setup with the 044
Thanks in advance.
