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.
1/8" female NPT thread at the front to connect fuel pressure sensor or fuel gauge.
1/8" female NPT thread for vacuum connection.
- Adjustable Fuel Pressure from 2.7-5.1 Bar (39 to 74 PSI)
- Compatible with gasoline, alcohol and race fuels*
- The fuel pressure increases 1: 1 with the boost pressure.
- Very reliable BTR with long service intervals.
- Specially designed membrane to ensure free moving parts without limitation and longer service life.
- Big diaphragm area to ensure stable fuel pressure and minimize fuel fluctuations.
- Sealed top without air leaks, market's first and only.
- Capable of 1000hp+ applications.
- Air connection for silicone or pneumatic vacuum hose.
- Spare parts are available.
- Inputs have female thread (2xAN10) to fit both O-ring seald and washer sealed fittings.
- Outputs have female thread (1xAN6) to fit both O-ring seald and washer sealed fittings.
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.
All SPD products have the absolute highest quality and are carefully tested to work in the most demanding motorsport.
*Race fuels require shorter service intervals.
SPD performance parts
SPD Performance Parts are quality products for oil, air, water and fuel systems. Developed to meet the highest demands of motorsports. All products are carefully tested both in virtual and controlled environments, as well as on the street and race track where they will ultimately be used. SPD products are developed and tested by experienced technicians as well as racing drivers to maximize functionality and reliability. With these extensive tests, the same high function is also ensured over long periods of time.
When such extensive tests are made to ensure quality over time, the full 5-year full warranty is given on all SPD AN-fittings and up to 3 years on other SPD products. Even for those who use them in racing and the most demanding motorsports. SPD performance parts are probably the only ones having such generous guarantees on motorsport products.
