Hey Dennis.
Sorry for not getting back to you. I work at science museum on Tuesdays
(today) and waited to get model number from strobe I use there. It has
adjustment from 0 to 8k flashes per minute. Highly flexible. But we obviously
bought it from some low volume supplier...."Way Cool Products". I couldn't
find it on the web.
Here is link to good price.
Not sure of flashes per second, I was looking for 40 to 50 but nothing
out there. Should work fine though if it's 20 fps, as we want to use it at 1/4
or 1/2 the engine rpm. That allows you to see the movement. If you operate
strobe at engine rpm, then you don't see anything.
This is important safety concept that's normally invisible to us. Glad you
are pursuing.
To answer some questions on the fuel plumbing at the fuel regulator -
The fuel system feeds from the left tank using 3/8 al. tubing into
parallel high pressure fuel pumps each with it's own outlet side GM
filter. The pumps and filters are mounted on the floor between the
rudder pedals (RV -7A). Output from the pumps and filters goes to the
firewall using 3/8 al. tubing. From there 3/8 SS. Airquip hose feeds the
primary fuel rail. Out of the fuel rail a 3/8 al. pipe connects the
lower primary fuel rail to the upper secondary injector fuel rail.
(Based on comments I will install an Adle clamp on this tube.) A 3/8 SS.
Airquip hose connects from the secondary injector fuel rail to the inlet of
the pressure regulator. The regulator return line exits the bottom of
the regulator and returns fuel via. 1/4 al. tubing to the left tank by
being tee'd into the fuel line from the right tank. The right tank
fuel is pumped to the left tank - copied from Tracy. The regulator
is also plumbed with a small-orifice bypass al. tube tee'd into the fuel
return line. This line exits left side of the regulator. This
bypass orifice was installed to quickly get rid on any air or vapor lock in
the system.
I will check into replacing the 1/4 al. tubes at the
regulator and from it to the firewall with SS Airquip hose. If this
can't be done on some of the short hose I'll add dampening or additional
support. I believe I have enough hose and fittings left over to accomplish
this!!
Did Al Wick or someone else have an inexpensive source for a
variable frequency strobe? I may be able to borrow one but don't know if
it is still available.
I want to THANK EVERYONE for the
review and all the comments. I hope to assemble the A/C and have
it in the air within 90 days.

see your rubber engine mount in the second photo. I appear to be getting
some engine vibration through my rubber mounts which are much thinner than
yours. What mount are you using?
Answer:
Fred at Conversion Concepts built the motor mount and supplied the rubber
motor mounts. They appear to isolate the engine vibration real
well.
It appears we need a new source for motor mounts!!
