My TWM
throttle body I purchased from Dave Atkins has two injectors already installed
on the throttle body. It also has the fuel rail, and I have still in the box,
the fuel pressure requlator. I assume that my fuel flow will go from the
tank, through the fuel tank selector valve to the fuel pump, then through the
pressure regulator, to the injectors. My question is.....do I need to
allow a return to the fuel tank for unused or excess fuel? If so, do I
take it from the fuel rail opposite the pressure requlator? I am, unfortunately,
a complete layman when it comes to fuel injection, so please be gentle on
me.
Here's my understanding of it. Someone correct me
if I'm wrong. Fuel injection would be plumbed as
follows: tank - selector - filter somewhere before the pump usually - fuel
pump - one end of the fuel rail - the other end of the fuel rail goes to the
input of the regulator - the output of the regulator is return fuel that goes
back to the tank.
I
noted that on the injectors that came with my engine, that the injectors have a
small tube protuding 90 degrees from the injector, which I assume was for the
purpose of returning fuel to the tank?
Can you post a picture of this tube? I'm not sure
what that would be.
The rotary scene is getting pretty interesting in our
little part of the world isn't it? We should have 3 new rotary aircraft
flying by the end of the year, and all within less than a 100 mile radius
:-)
Cheers,
