Boost controlled fuel pressure regulator.

At cruising vacuum low pressure the system pressure is lower and at full load the pressure is higher accordingly. Boost reference enables fuel pressure to be raised 1 1 with boost pressure overcoming the rising air pressure and making certain the float chambers remain properly filled. Fuel pressure regulator with boost control 35 85 psi gasoline alcohol aluminum blue anodized each. Summit racing gift cards always the perfect gift.

During these moments the fuel pressure regulator temporarily shuts the fuel return line. Boost reference enables fuel pressure to be raised 1 1 with boost pressure overcoming the rising air pressure and making certain the float chambers remain properly filled. With all else being equal for every amount of pressure change that occurs at the pressure reference port an equal change in fuel pressure will result. These fuel pressure regulators are easy to get on ebay the preload is adjustable between 3 and 5 bar.

I m planning to keep the stock fuel pump and to keep 3 bar fuel pressure however with boost control so 4 bar abs 1 bar boost overpressure. This happens because the fuel injectors open wide quite suddenly. The system pressure should add the boost pressure to the original spring controlled regulator pressure. With all else being equal for every amount of pressure change that occurs at the pressure reference port an equal change in fuel pressure will result.

A boost reference line is run from the intake manifold to the vacuum boost reference port. The fuel pressure regulator compensates by increasing pressure using the vacuum boost reference. When a fuel pressure regulator is referenced to manifold pressure it acts to mirror manifold pressure changes with equal changes in fuel rail pressure resulting in lower fuel rail pressure with manifold vacuum and higher fuel rail pressure with boost. Boost controlled fuel pressure regulator does it work.

This should work with boost also. As a result this helps in boosting up the fuel pressure for a few moments.
