The distance is along the upper surface of the exhaust pipe.
I would not go too crazy on exactitude since GA grade EGT meters
are not terribly accurate anyway, i.e., 50C out of the box without
careful calibration.
The main idea is to have all the EGTs installed at the same relative
distance from the valve so they are comparable. (I have 4 EGTs
and 4 CHTs on my 912s into my Blue Mountain)

I see no present reason to replace the original fuel pump with the 'new'
unit. Should I await some problem before doing something, or should I go
ahead and replace it before problems (if any) arise?

My 912 stopped charging, and when I checked the yellow cables from the stator,
they were fused together. I soldered new cables on. After I replaced the yellow
cables, the charging worked fine, but then it only fired on one mag. I then
checked the cables from the stator to the ignition box, and found them to be fused
together. The insulation on them was soft and could be pealed away with a
finger nail. I changed them too, and will keep an eye on them. I believe rotax
had a recall on these stators 10 years ago. Attached is a picture of my red
cables

If you have a older 912 where the cables from the stator to the ignition box are
not separately shielded, I suspect those to be the culprit. Please see my post

Not to worry. When my old fuel pump went bad, fuel just dripped on my

Fuel Pumps good or bad---- While on our annual trip to Pittsburgh from
Florida last weekproble in the S7S while checking the plane at FWQ I
noticed a fuel stain on the front of engine. Next I felt the fuel pump
and it was wet and dripping and I then turned on the electric fuel
pump and the fuel just about poured out of the eng fuel pump. Due to
the location of the fuel pump I consider this a very serious problem.
I was able to get a new pump from Lockwood over nighted and we
continued the trip. My plane has 850 hrs on it and the pump had about
650hrs as the original was replaced by a SB under warranty.

Hi Ollie,
I'm not sure what you mean by location?
If your fuel pump leaks or the diaphragm goes bad by all means change it, but I
don't see a reason to toss a pump in good working order out to just install another
pump, which as of right now is unproven just like the last pump was for
the first year.

This may be true, but I just changed mine on a trip because I noticed
a fuel stain on front of engine and when I turned on the electric pump
fuel just about poured out of the eng. fuel pump. Now the problem I
see with this is the fuel pump sets right over the exhaust and being
on the front of the engine leaking fuel can blow back over the hot
engine.

You might want to check the output of the dynamo (alternator) and use a
scope to see if your regulator is failing and allowing AC into your system.
Have you noticed any battery charging issues? Is there anything else on this
circuit that could be drawing a lot of amps and / or shorted? Whatever
caused it certainly let the smoke out of the wires.

Rotax made two visible design changes with this new pump.
(1) it's now "bolted together" instead of being pressed together. Apparently, there
were failures at the crimp, where the two halves of the pump were crimped
together.
(2) Instead of a weep hole (or whatever its called), they now have a regular fitting
on the pump, where a "drain line" is connected. This is to allow raw fuel
to be drained away from hot parts of the engine.
But I agree with the pump location. Its awful hard to avoid hitting the cylinders,
or the hot muffler underneath the engine, should raw fuel come out of it,
even with the new drain line. I suppose one could get fancy and route the new
drain line away from all those areas.

When my pump failed, it dripped fuel on the exhaust. Roger told me it
was a failing fuel pump. Could be, that's why the older pump was
changed. I would consider running the engine, shut it down and check
for fuel pump leaks before each flight.

Did you recently de-grease or wash the area with solvent of some kind? Rotax told
me years ago that
that was the cause of the problem.
