V3 PRO is the latest version of the fuel pressure regulator. This FPR is based on a new construction that delivers superior precision and reliability.
Improved control of diaphragm and spring, improved seat and return, several different adapters for the internal return feed to be able to match different fuel pumps and fuel systems optimally.
Each fuel pressure regulator comes tested and leak free.
SPD's fuel pressure regulator is specially designed to work well on alcohol fuels. The fuel pressure regulator has our new generation internal components where materials have long life and high reliability when driving on gasoline and especially ethanol that is very aggressive. The regulator is designed to handle high return flows at low engine load while ensuring that it's able to raise the fuel pressure 1: 1 with the charge pressure even when very powerful fuel pumps are used at high power outlets.
We stock all spare service parts.
This is one of very few FPR's on the market which does not leak air at the adjusting bolt. Built-in top screw sealing kit that is pressurized and tested up to 7 bar air pressure without leaking.

Choice of adapters is made in the drop-down menu, select which inputs and outputs you want.
If you only have a return from the fuel rail, "Plug" should be selected on input two.
If you have dual returns from the fuel rail / double fuel rails , you may choose the appropriate size of input two.
