I plan on experimenting with the low pressure dribble fuel injection
system. I have the pix of the 1/8" miniature regulator you shared with
the list. I found what looks like the one you mentioned at McMaster Carr
(# 6763K11), but it is the relieving style so it vents if the regulated
side exceeds the selected pressure. NOT GOOD for fuel to be vented!

Can you tell me the source for the regulator in the pix?

It is this little jewel right Doc?
It has three pipe threaded ports so you plumb the return flow
back to the fuel tank exactly what must be done using
Tracy's EFI system. The only ones that don't do this are the
computer controlled PWM fuel pumps.

That is the one I meant. Who is the supplier? I will order one to play ...
err design with. :)
