Anyone ever tried to get a field approval for an external boost pump?
I went through 2 boost pumps on my 560 and 3 on the 685.
These damned things are terribly problematic.

I BELEIVE CENTRAL AIR HAS AN STC OR FIELD APPROVAL ON 5OOB.
I KNOW SEVERAL COMMANDER DRIVERS WHO ONLY TURN ON BOOST PUMPS TO START ENGINES,
NEVER DURING FLIGHT. NOT A SAFE IDEA,BUT PUMPS LAST LONGER.....

"Not a safe idea?"
A little boost pump trivia.
The Pratt and Whitney powered Douglas DC-8 was designed to take off and land
with the boost pumps off. Supposedly, Douglas felt if you wrecked it at
least the boost pumps wouldn't be pumping fuel into the fire. I'm not sure
why they thought you would have electrical power for the pumps to run
though.
The end.

Remember when Cessna 300 and 400 series had HI/LO boost pumps that were
pressure switch activated? If fuel pressure dropped below a certain value, the
pump would kick into HI output.
More engine failures were caused by engine flooding than anything else and
Cessna had the pressure switches removed.

Milt,
Where was the fuel pump on your 685? I would have assumed that it was in
the same place as my 680 (in the nacelle). They are a little hard to get to
but not in the tank.
