Bought this car from a boy-racer, he added non-original crap and i want rid of it, mainly cos its causing high fuel consumption, 21 MPG
Heres the piece i found

It leads to the boy racer adjustable fuel pressure regulator so im curious as to what it could be.
It leads to this

Any ideas???
Im replacing the fuel pressure regulator with an original one so im wondering should this also be removed?? (the thing in picture 1)
No idea what it is or what its function is.
Thanks
