[928uk] CIS fuel line

[Paul R Smith]

 From the position on the diagram, I think the 189 one is the one which 
goes from the fuel distributor direct to the WUR, I think the 
description is misleading (it says warm up valve diaphragm, not warm 
start diaphragm) , and the 190 numbers which are described as "return" 
are what you want.

You definitely don't want one shown as -79 as on those the WUR is in a 
different position, and I don't believe they had the warm start circuit.

Also, with the warm start circuit, there is one pipe going from the WUR 
to the warm start solenoid valve, another going from there to the 
damper, another one from the damper to the fuel distributor and yet 
another going direct from the solenoid valve to the fuel distributor. 
Where are the rest of these on the PET?

What exactly is wrong with the one you want to replace? They don't 
usually fail.
