is there a way to install this

 

not with the way our cars are controlled. Your car wouldnt adjust to the loss or gain in fuel. you have to change the values in HPT. but im sure someone else could eleberate if u have questions...im just a lowly 2.2 owner

 

I know for a fact that 2.4's can use fuel pressure regulators. however, it is much better to have the factors be changed via a tune or tuning software.

 

yeah you have to pretty much convert to a return style system
