[urq] [Es2] Fuel Fitting enigma

[Peter Antonic]

Ben, I am running 3B intake and 3B fuel rail on my 7A Coupe. Youa re
right, the 2 lines on the Coupe are different size, but, you should be
able to use a 3B line -- the long one that connects to the front of the
rail(feed?), and then 7A line from the hard line on the firewall to the
fuel pressure regulator. From the FPR, you can again use that curvy
little 3B line and connect to the rear of the rail. 

It worked for me. Here's the only picture I have of my engine bay from
some time ago...I can snap a newer one..

Peter,

Maybe you can help Ben Swann with this?

I have searched now for days for what should be a trivial part.  I am
trying to mate fuel rail from 200Q20V to Coupe Q with formerly 7A
engine.  Most of the other Audis all have two fuel connections to and
from the tank that are 14mm X 1.5 "inverted" flare or ball flare.  In
this case however, one line is 16mm x 1.5 same type of fitting.  It is
the type shown  here:
http://web.mit.edu/kcedrone/www/mefi/plumbing_ID.pdf
 but the NUT
is  M16x1.5 thread instead of 14mm.

I was hoping to find a single fitting to minimize connections - a
fitting that would adapt the 16mm fitting to the 14mm line to the fuel
rail.  The fitting would have a 16mm
X1.5 inverted flare (female) on one side and a 14mm x 1.5 male flare  on
the other.

The closest solution I have found so far is a 16mm Female metric with
O-ring to -6 AN.
I'd then have to convert back to 14mm flare using no less than 3
fittings in-between or having to make up a custom line.  None of this
will be as slick or safe as the nice braided SS factory lines with
single adaptor in between.

I looked at many of the good sources that were provided and really not
finding an obvious solution.  There is probably a shop that handles
esoteric Bosch fittings like what I'm looking for.  I must have 100's of
different adaptors in my bins and even one that is close - only it is
14mm female, not 16mm.  Some other adaptors I have are flat-faced or
tube, so don't think this is ideal for a positive seal.

Without going into further details, I'm hoping someone has an ideal
fitting I'm looking for or knows where to get one.

Help!

Ben
