You dont need one, and the pressure reg you bought is standard.

How is it "uprated" maybe its squashed in a vice to up the pressure (seen it done before), in which case its shite as most cossie setups are made to run with STANDARD pressure.

Only use of a "uprated" fuel pressure reg is if its an adjustable one (and many cossies (all but esc cos i think) come with an adjustale one as std.

Uprated pump is a good plan, but regulator will make things worse unless the GGR chip specifies a higher than std fuel pressure.
