Hmmm...Saw this post off the Sunny delphi forums...Is what he describes true??

==============================

 

After adjusting the pressure, did you pull the throttle cable to check

the max pressure at the guage (PBV function check) ? Off the engine, did the pressure meter drop steadly to 0 (Fuel return line efficency check) ?

 

==============================

If yes, then maybe I will reinstall my stock fuel regulator, cos my aftermarket one seems to remain at 2 bar for a while (say several minutes) even after turning off the engine?? Or is there a clog somewhere on the return line??

Yes, even after turning off the engine, the pressure is still there.

 

It takes at least 30min before the pressure drops.

Easily identified... look at the fuel injector rail. At the end is a round shaped device, that's the fuel regulator.

 

However, doesn't apply to all cars, e.g. G9 Corolla and iVTEC which doesn't have a return fuel line ....
