C14SE Fuel Pressure regulator, fix or replace ?
How reliable are these things do they get lazy? Wonder if mine is as there is hesitation acceleration.
I've replaced the pipe that goes between it and the inlet manifold since pic was taken.

Vauxhall want about 45 quid for a new one. Cafco can't tell what type my car has without me taking it off and looking for the part number.
Can I service this item myself?
selaled unit so you cant service it youself, have you tried changing the fuel filter?
get a set of new vaux plugs
this cured hesitation on my dads c16se, which is almost identical to yours.
Bingo! Larry the Lamda
It turns out its Larry the Lambda sensor giving eratic readings and casuing a lean mixture. (Took it to a guy with a diagnostic computer).
The earth path from the sensor is fine so it might just be needs replacing (about 28 quid).
Does anyone know what sort of output you should get when you put an osilloscope on the sensor (obvioulsy when engine running)?
