This 5 Volt power supply might be a good value:

I have purchased various items from them over the years

Guys,
What size wire should be used for the feed from the smaller third pin of the military
style power receptacle to the (+) OVM sensing connection post? Since mine
is in the engine side, I was going to use 18AWG. Is this acceptable?
Thanks,

Looking at Bob's wiring diagram in Appendix Z, 31A, for a military

It's a sense pin and it is hot, the same as the center pin. Without
the plug, it is not connected to the center pin. It can be used as the
drawing shows, to separate the source of power activating the
contactor from what is flowing through the contactor.
This allows you a way to take action on this pin going hot. In the
case of Z31A, that drawing shows polarity and overvoltage sensing
being done from that pin."

22AWG fine for the current but you can
go bigger for mechanical robustness. Some
OEMs don't run anything smaller than
20AWG in engine compartments and/or
wheelwells. 18AWG is fine too.

Those are higher pressure (7.5 psi) sensors than john asked for.
Working with a cabin tank and gravity fed fuel line here (no fuel pump).
How would it be plumbed and wired into a gravity fed fuel line from a cabin tank
mounted between the instrument panel and the firewall, with the fuel line routed
from the bottom of the tank going forward to the firewall mounted gascolator,
and finally to the carburetor?
What gauge would work with it?

Finding such a critter with a full scale
range that small is problematic . . . especially
one with all metal pressure-side materials
that would be okay with gasoline.
Suggest you look at something like this
http://tinyurl.com/9uw647y
http://tinyurl.com/8unuxge
http://tinyurl.com/983v7o7
http://tinyurl.com/99xfyrs
This is a small sample of possibilities.
They're all aerospace grade devices at
very reasonable prices compared to off the
shelf new. Even as used devices, transducers
of this genre' are likely to be a better
value than automotive devices.

Subject: | CbOV-14 Crowbar OV Module - extra part? = MBS4991 |
Bob,
I bought a CbOV-14 Crowbar OV Protection module from you awhile back. In the plastic
packet is the module, along with a small transistor MBS4991 separate from
the module itself.
Is this a spare in the event that transistor needs replacement at some time in
the future? Should I just put this in my long term maintenance box of parts?
I just wanted to be sure I wasn't supposed to install it as well. I'm using the
CbOV-14 module for my Ground Power Jack per your article "Low Cost Ground Power
Jack for your airplane."
Thanks,
Howard

Guys,
I'm installing the CbOVM-14 OV Protection module and wanted to confirm if it's
ok to install this on the engine side of the firewall (HOT), or should I put it
on the Instrument Panel side (COOL).
It would be a little easier with wiring to zip tie it onto my Ground Power contactor
terminal wires on the engine side, but I didn't want to do this if over
the airplane life I'd eventually fry the thing.
Sounds like either side I choose, the installation mount method is to just tie
wrap it to some wires. If others have a better idea, I'd appreciate the tips.
TIA for your comments and help!
Howard

Subject: | Re: Fuel Pressure Sensor search |
If it is just gravity fed, what is the point of a pressure sensor? If you are planning
to use it as a fuel gauge, that
would be not so easy. The majority of the gravity fed head is from the bottom
of the fuel tank in the wings to the
point of use. The head pressure in the wing from full to empty is a small fraction
of that. So you would need a sensor
that can withstand avgas (or autogas if that is what you are using) that could
measure only a few inches of water
(fractions of a psi). Possible, but not so easy.
Dick Tasker
P.S. We (www.astsensors.com) do make sensors that will measure down to 5 inH2O but the cost is not particularly
appealing for this type of use.
