I used the stuff from Abbey at flightline as others have said. Doing it was
very difficult after the plane was finished and it isn't near as good a job
of sealing up the edges. Definitely do it while you have access to the back
side.

Subject: RV-List: Re: Firewall insulation for heat and sound
I'm just about to the point of putting on the front deck of my 7A and
thought it would be easier to put some insulation on the aft face of the
firewall now. There are several types advertised -- I was looking for ease
of application and good performance in reducing heat and sound from the
engine. Does anyone out there have a favorite type??? Do you feel that it is
worth the effort to insulate the firewall?
I'd appreciate your comments

When selecting firewall insulation material, it might be assumed that
the manufacturer (amateur builder) looked at flame propagation time or
just dismissed the guideline published for certificated aircraft in the
AC. (Which is often a great "jumping off" point in decision making).
Firewall insulation, upholstery covers, carpeting and headliner are
often grouped with other "thermal attenuation" and "sound attenuation"
products. Some products can do both - they are not always the same.
Fire Suppression and flame spread were not listed other than in the
description.
Often the adhesive used invalidates the purpose for the product in the
first place.
The ability to remove it and locate corrosion years later should not be
dismissed without reasonable consideration. Too often in our quest for
completion we totally dismiss "fire annunciation" and "fire suppression"
objective of safe building.
I had a friend who recently crashed in Virginia, only to extract himself
after his canopy burned away adequately. He was in serious condition
afterwards.
Below is the NTSB report of Boriak's accident. I read in an aerobatics
newsletter that he was inverted after the accident and couldn't get out
until the canopy melted.

Thanks for the comments I definitely will use some insulation,
although I'm still unclear as to which product to use.
Currently leaning towards the Flightline Interiors product.

| Subject: | Low Fuel Pressure |
With the boost pump off, my fuel pressure in flight normally stays around
the bottom of the green arc (Van's gauge). Yesterday I was flying 22 squared
and saw that my fuel pressure had dropped to 1 psi which is just a fraction
above the red line. The engine ran fine, but I got very concerned. I turned
the boost pump on which slowly boosted the pressure up to the bottom of the
green arc, but no higher. Normally with the boost pump on (such as on
takeoff) I can get the pressure up to 5 psi (top of the green arc). During landing,
with the power pulled back, the fuel pressure rose and behaved normally. I
am concerned that for a period my fuel pressure dropped almost to the red
line. Have any of you had a similar experience? (My mechanical fuel pump
diaphragm is not leaking and my fuel lines are plumbed as per Vans.)

Hi Pete,
I have had similar experiences with Van's fuel pressure gauge though
never to 1 psi. I see variations from the bottom of the green arc to
middle of the green arc. There has never been any indication from the
engine of lack of fuel. The indications seem to be independent of power.
The boost pump will sometimes bring the indication to mid green when it
is at the bottom of the green arc on engine driven pump alone. The
variations seem to occur randomly.
I have an O-320-D1A with about 130 hours on it since new.

Tis normal in my RV. I biased my RMI engine monitor to add 1 psi
so it would not constantly blink. Otherwise it was often ZERO in flight
The engine has run fine for over 1200 hours this way.

Me too. Using grand Rapids EIS, same low readings. No problems in operation.
Also adjusted EIS formula to get reading of 3 as my new base. In last 200
hours has been consistent.

This a great fly-in if you can make it. There are normally several
hundred aircraft in attendance over the three days of the event.
Obviously Saturday is the better attendance day. Of all the fly-ins I
attend this one has been my favorite.
The dates are 10/12, 10/13, and 10/14

What was the altitude when you noticed the low fuel pressure, and how
long had it been since you climbed to that altitude? I've seen some
reports that suggest that some of the commonly used fuel pressure
senders are not very well vented, and it can take some time after you
climb for the pressure on the ambient side of its diaphragm to
actually decrease to the local ambient pressure. This causes the
pressure to read lower than the actual pressure.
