Fitting a adjustable fuel pressure gauge
 

Anyone got instructions on how to fit one of these or step by step guide? Fitting it into a 2003 wrx blobeye

First ask yourself why you need it.

Was told I needed one :-S

Don't you mean an adjustable fuel pressure regulator with a gauge?

Yeah sorry

What's the spec of the car?

It's a 2003 wrx mapped for 550 Sti pinks front mount VF35 Sti inlet exhaust manifold decat

Hks induction kit as well

You dont need an adjustable reg as your 550cc injectors are large enough for the potential power of the vf35. If you had 380cc or 440cc you could squeeze abit more with a adjustable reg but the fact you have 550cc's it would be a waste of money and any mapper will tell you that

waste of money at that powerlevel IMO, unless you just want it for the bling factor.
