M20 producing atrocious mpg. Update 15/6/16

Perhaps the Zone Wiki should be altered to include the FPR as a priority item to check if the fuel consumption is excessive...

That would lead to yet more random and unnecessary part changing.
Changing the wiki to highlight the importance of measuring fuel pressure as a diagnostic tool would be the way to go.

The FPR was perfect, it was the injectors that were the problem, possibly the breather pipe aswell, once those were rebuilt/replaced I damaged the FPR but obtained a drastic increase in mpg even with the damaged FPR.

I had 3 leaking injectors but the car starting/driving smoothly etc, emissions were suitable to pass MOT etc

Adding a section to the fuel issues page noting that poor injectors can lead to greatly reduced MPG despite a car running smoothly, my car was running so well that I really didn't think an injector rebuild would make a difference but it was night and day in terms of MPG.

Also as Brian says, FPR diagnostics would be helpful for someone suffering warm start issues etc.
