Cossie convert,

If I am not 100% sure about a technical statement I make, I will qualify it with something like "I believe". John made a statement with no such qualification, and it was wrong. This kind of dissinformation cannot help in any way, it can only cause problems.

Heard a lot of talk recently about the merits of fitting one of these to a normally aspirated engine (Sport) - I think TSL do them. However, nobody has been able to explain how it works and what it does exactly as opposed to a OE fuel pressure regulator. Any ideas greatly appreciated.

This type of regulator allows the fuel pressure in the rail to rise with engine rpm. The std. item maintains a relatively constant pressure. They can cure pressure related problems such as flat spots. The FSE item helped with a modified Mondeo (Turbo`d) I had but If you have`nt actually got a problem don`t bother.

Thanks John - I don't think I'll bother as they aren't particularly cheap with fitting!

John D is incorrect or just plain wrong.

FPRs regulate the fuel pressure in relation to the manifold pressure. Linear FPR's increase fuel pressure at a the same rate as the manifold pressure, rising rate FPRs increases fuel pressure in faster, non-linear fashion.

You are correct, however to be fair to John D, the FSE sales blurb presents a graph showing fuel presure rising at an increased rate plotted against RPM.

That will be why you edited your post then after a re read

My sincere apologies for making my reply too simplistic.
