Fuel pressure regulators

[NU13]

On a daily what practical use would one of these be? Are they mainly for looks?

Thanks Rex. As i thought they are pretty for looks unless going for an upgraded fuel system as well.

Well if you need it then it's all good but for a stock set up nah it can be used for bling factor thou. If you do decide to get one get a good brand( Sard/Turbo smart etc) not a trade me Chinese special. They leak fuel from seals and aren't accurate psi gauges on them are useless they can read 10psi +/-.

Better off saving the coin and putting it towards those billet fuel rails that Aeroflow make....
Fuel pumps pick up the slack in performance applications, so adjustable regulators are pretty much a thing of the past.
