Jeff,
No.
The design for the system is High Pressure port (with
High press sw) on the left. Reversing the wiring in addition to the
lines MIGHT allow function but the bleed off circuit and design pump
rotation (for high pres) would be wrong. Oildyne could tell you with
certainty.
However, it only takes about 15 minutes to pull and
reverse a spool valve.
BTW, if you have an older model pump, you do NOT
have the spool valve as pictured in Gerards post. In my discussions with
oildyne, I believe I understand correctly that the early model pump does NOT
have the bleed off circuit (like the guts pictured). Therefore, I'm not
sure of your specific problem/ solution. I guess what I'm saying is that
Oildyne/ Lancair never really explained why the pumps changed. I assume it
was for the bleed off circuit. Additionally, I've got one in my hangar
that chirps (a friends) and I'm not sure that our spool valve test holds any
relevance to his pump. Chris Z? Any thoughts on the early
models?
Post repair inputs are perpetually
appreciated.

For the reversed spool valve problem, could one not also just flip
the lines on the ports ? aka cross them ... meaning if high was on the left move
it to the right? thus the spool valve would then have high pressure on the
correct side ?
or does this pump have other items that cuaseit to have to
flip the spool valve internally.
I guess the question is why does the
HIGH side of the pump need to be on the left while facing the pump ? is it only
cause the spool valve ? or is there something else in the pump that needs to
have the high side on the left ?
Wondering ....
