Bill,
Bulent just about described my system to a Tee. Only thing I can
add is to consider installing a bleeder circuit which bypasses the
regulator that can prevent an airlock in the system if/when you run a
tank dry. The Eggenfelner Subaru bunch had a couple of
"mishaps" that was traced to that problem. I was able to
duplicate that serious fuel system shortcoming on the ground. The fix was
to install an air bleed circuit as I have described above.
Quote from the Eggenfelner site:
|
| A mandatory
fuel regulator and regulator bypass bleed valve kit is now available and
is required in order to regain fuel pressure in an installation where
fuel cavitations is likely. This is any low winged airplane with an
unshielded fuel pump installation operating in summer temperatures on
auto gas. Vapor lock can occur in any airplane however so this upgrade
still should be done. Engines delivered from May 2004 have this
installed. |

How does the 3 port work? One line in (fuel supply), one line out to
injectors, and line from regulator back to tank? in this case wouldn't
the line from regulator to injectors be dead-ended?

JIm,
I'm using a 3-port Mallory fuel pressure regulator. It is supposed to be
capable of regulation between 3 and 65 psi. They have other models as
well. See

I'm still wondering if:
Can any (or all) electric pumps can be plumbed in series and pass fuel
when shut off
Are there any regulators that can be adjusted as low as 25 psi
Does anybody have these answers for me ? ... Jim S.
