Wally,
I mounted my fuel pump as you suggest, for a level flight attitude, 1500 hours
ago...still works fine. While you're down there, hinge a door over the battery
compartment, buy an odessey battery and mount it out on the firewall and turn
that area into a forward baggage area.Save yourself 10 pounds, have better
cold starts and save some space as well. Forget a center console between your
legs, adds weight, takes up space and is completely unnecessary. Put plenty
of firewall insulation under that floor while you're there as well, especially
if you use a Vetterman 4 pipe. You might as well route a 1" scat to the back
seat through the stick well and have rear seat heat while you're there as well,
you'll wish you had it for your back seat cutie in the winter.Make a nice diverter
scat where the heater enters at the firewall and forget front seat heat,
have it come out behind the front seat, much better. And....while you're back
there, build up a set of rear seat footwells, you'
ll wish
you did that too. OK, while you're there, might as well get some decent stainless
braided NAPA brake lines too. The plastic ones started leaking after 5 years.
Be sure to route a cooling scat to your avionics too.Have several good fresh
air vents too, I like the Vetterman "turn-out" vents, 4 is perfect for summer
flying. Why do I babble about all this, that is every change I made AFTER
I started flying it.
I bought a Wal Mart automotive OAT and put the sensor out one of my fuel tank
vent tube holes. If you use a standard aircraft OAT, I have seen them mounted
with the sender sticking through the inlet of a standard Vans fresh air NACA
duct. Really, you could put it anywhere above the fuselage water line and get
good results.
Good Luck!

1. 06:40 PM - FACET FUEL PUMP AND OUTSIDE AIR TEMP QUESTIONS (RV4WGH@aol.com)
________________________________ Message 1 _____________________________________

Subject: RV4-List: FACET FUEL PUMP AND OUTSIDE AIR TEMP QUESTIONS
--> RV4-List message posted by: RV4WGH@aol.com
I am in the finishing kit stages of an RV-4 and have a couple of questions:
1) Facet fuel pump instructions say to mount the pump on a 45 degree angle.
Knowing this pump is an automotive pump, is this also important in an
airplane? Seems like the pump will be at a 45 degree angle most of the time in
a
tail dragger, at least for take-off. I had planned to mount it in a manner
that would make it level in normal flight.
2) Where is the suggested mounting location for the outside air temp sensor?
Thanks for any suggestions.

Rob - you made an interesting post. You say " Put plenty of firewall
insulation under that floor while you're there as well, especially if you
use a Vetterman 4 pipe." I am a bit puzzled here. Is this to keep you feet
warm or cold? Is the heat coming through the firewall or is it just radiated
heat coming of the exhaust pipe tails? I am puzzled because its mostly fresh
air under your feet.
Re ".the back seat cutie" I have decided to solve this problem with electric
seat inserts. I decided I just did not want to start cutting holes in the
spar, especially when VANS were not prepared to say exacvtly where.
(Phlogiston said they were more than happy to cut the hole if VANS would
just define where. They would not.) I just mention this for the sake of
other builders, since I spent ages trying to work out how to safely get heat
back there.
Finally where did you put your oil cooler? On the back of the baffles (LHS),
hanging from the tubes of the engine mount, or on the firewall? Do all these
locations work equally well?
Thanks Steve.

See attached photo - the 12V computer cooling fan works great on hot
summer days with prolonged ground ops - otherwise I see 180 degrees on
all but the coldest days. This is 5 layers of metal to prevent cracking.
