[urq] Warning about Fuel Pressure Accum.

[Phil Payne]

>  What I am calling Fuel Pressure regulator is the Zinc Chr. Plated Cyl. you mention, and I
have for the time ruled this out as you mention failure IMO is rare, but that was one of the
questions I had asked.

We could do with some serious post trimming on these lists.

I think it was Scott Mockry who discovered that this device is adjustable.  If you remove it,
a long Allen key (I've forgotten what size, but I know it's a freaky half - 3.5mm or 4.5mm)
passed into the unit from the tank return end will engage in an internal Allen screw.  From
messing about, I suspect it's a residual pressure adjustment - but I know that just fiddling
with it has restored a failed unit from 5.2 bar to the stock 5.85 bar.
