<E30> 86 325e, fuel line connections (path of flow)

["Milliet, Ron P." <RPMILLIE@xxxxxxxxx>]

> I bought this car a month ago and just got it running this weekend.  The
> fuel system appears to have been hacked by PO.  According to the Bentley,
> there is a single supply line that feeds the press reg and a single return
> line use for recirc of excess fuel.  It is not clear how the cold start
> valve get its fuel.
> 
> Can someone please provide a drawing or description of the fuel flow,
> starting with transfer pump in tank?? What feeds the cold start valve?
> 
> I think it goes like this:
> 1. trans pump - in tank
> 2. fuel pump - left rear wheel area
> 3. pulse damper - next to pump
> 4. fuel filter - engine compartment
> 5. Pressure regulator - front of fuel rail
> 6. exit the back of the fuel rail
> 7. to cold start?? or back to tank? other component?
> 
> The above may be completely wrong.  All help will be greatly appreciated.
