Hi Finn,
Since you appear to be uncomfortable
with barb fittings, here are the ones I
used for over 10 years that have a
screwed on fitting, never had any
problems. Replaced them ever 2
years, cut them open and could never detect
any trash in fuel system. I
started with an AC GF-481 which became hard to
find and then switched to a more
readily accessable NAPA filter the GF652
NAPA FIL-3481. They do require
the Saginaw fitting and an "O" ring.
Fuel Filters:
OEM Auto Fuel Injector Fuel Filters (Two in
Parallel)
Type:
AC GF - 481 Pkg: 25056052 OEM:25055129 (or
equivalent)
Replaced by GF652,
NAPA FIL -3481
Fittings:
3/8 Saginaw to AN6 Adapter, “O” ring required
Best Regards
Ed

Have you searched for an inline fuel
injection filter with NPT threads?
You can use NPT to hose barb adapters.
Summit has one that looks like
the NAPA all metal filter several
builders have used. It doesn't list
filter media or max psi on the site,
but it might be worth a look.

Hi Ed,
I'm not uncomfortable with hose barbs as such. All fuel
lines forward of
firewall are Aeoquip "hose barbs".
Considering inside area of 3/8" hose (0.11 sq in) and 80
psi
(more than
twice my normal operating pressure) and how hard it is to
press on the
hose onto the fittings, a 9 pound pressure trying to press
off the hose
seems minor.
I'm more concerned with the quality of the filter (can)
itself. With all
the high pressure car EFIs out there it should be possible
to find a
filter with hose barbs -- but maybe not the quality of the
Aeroquip ones.

Todd,
When I was racing motorcycles the tight fairings were
always
a problem.
Until Ti came into more common use I, cheap bastard that I
am, always
railed against the cost sending a brand new pipe to
jet-hot.
But I did it
several times and the result was always a pipe that didn't
corrode. I never
had one crack or fail in 10 years of race bikes.

So this begs the question (at least to me) if we have a
muffler in line whic=
h you really can't coat in and out, will coating the
header
cause an increas=
e in thermal wear of the muffler since the exhaust gas
will
be hotter?

I had found something about that VHT dramatically reducing
underhood temps,
but after searching to find where I saw that, I realized
it
was a teenager
in a YouTube video. So much for that.
Next week after I do some more engine runs. I'll
remove the exhaust and
ship it out, as I'll be away on a climbing trip with my
son.

I'm one of those that had my rotors coated back
around
2001. My reaoning
was that it would transfer less heat to the oil so
therefore
reduce my
cooling requirements. Unfortunately I originally did not
have an electronic
boost controller and experienced an overboost on one
eventful takeoff which
led to me discovering that the rotary is indeed very
reliable and can
tolerate severe detonation and continue to produce enough
power to safely
complete a flight.... but won't start again afterwards.
(The
full story is
in the archives and may be worth a read).
Anyways, on teardown I found that most of the ceramic
coating had flaked
off, more on the rotor that had withstood the greater
detonation damage to
the apex seals. Now that wad probably quite a shock to the
coating, far
worse than they can normally expect to see.
After I rebuilt without redoing the coating I good
see no appreciable
difference however I didn't have enough data collected
from
before to say
for sure.
Recently, however I rebuilt the engine and I could
still see the remaing
ceramic coating on the rotors that had survived the
detonation incident.
The engine probably had about 50 hours on it after that,
so
it would likely
have lasted much better under normal use.
