Everyone thanks for your
response.
After lengthy evaluation and
communications with Dukes and CJ aviation I have learned the
following.
The Dukes pump is designed for
“intermittent duty only” and is not a self priming pump. It does not have a
thermal overload relay. I also found out that the tolerances in the pump are
not well controlled.
Unfortunately I have been unable
to reproduce the failure that I experienced last week. All electrical
connections check out properly. The aircraft only has 140 hours on
it.
I have decided to replace the
Dukes pump with a Weldon pump.
The Weldon pump is designed for
“continuous duty” and is self priming. These are two big advantages over the
Dukes. Also the tolerances are well controlled.
I have ordered the Weldon pump
with electronic controller from CJ Aviation. I will have the pump by the
beginning of next week. Which is a much better delivery time than getting a
Dukes.

Has anybody run into
this problem?
Yesterday after
flying into a field the Dukes of electric fuel pump would not run at all. I
was forced to leave the aircraft at the field because I couldn't get the
engine started.
The field elevation
was 1300 feet and it was close to 90°. The density altitude was about 3000
feet for the day.
Today I returned to
the field tools in hand to carry out a rescue. Surprisingly the electric fuel
pump worked!? Why?
I was able to fly
the aircraft home.
I concerned about
flying the aircraft until this issue is diagnosed and
resolved.
