Will the Lucas Harness Smoke also work for semiconductors or is that a
different part number? I presume it is installed with a standard
syringe.

Hi
Lynn,
Funny you
should mention this, because I've actually been contemplating a single pump
system on the single rotor. These pumps are quite reliable, and seem to
give lower readings as they start to wear. I could probably argue
that all the extra plumbing and wiring might cause more problems than it
avoids. Also, no one seems to mind running a single regulator, but
that could fail just as easily.
One thing
I keep thinking about is a conversation I keep having with a couple
RV buddies. One guys wants an auto conversion, but only if
it's as reliable as his car. The thought being that you get in your car
and drive thousands of miles, and don't ever consider what whether the
engine might break on the way there. Using a modern car as the
reliability standard, you have to accept that there is only one of everything
(ECU, fuel pump, etc).
BTW, just to
let you know how abby-normal I think, I used to run both pumps all the
time, just as I also run my boost pump (almost) all the time for the
Lycoming. My logic is that I'd rather find out about a pump
failure when I'm safely on the ground, checking them individually
during my run-up.
I'm certainly not telling anyone to take out their backup
pump, but I'm wondering if I might just leave mine
out.
Cheers,
