The pump will not work if either check valve is leaking.

Subject: [LML] Emergency gear pump/door seal - IVP

I just removed and inspected the emergency gear pump after 740+ hours.
There was a scuffing on the interior cylinder and obviously with this many
hours the top seal was leaking fluid.  The emergency gear pump worked during
this whole period, sometimes hanging up with, I think, one of the check
valves sticking.  After rebuild and smoothing out the center bore, I am
finding that the pump will not charge and wondering if others are having
problems with their emergency gear pump.  What have you elected to do to fix
it?

Door Seal:
On my fifth door seal in 8 years and in each case the seal began leaking at
the vulcanization point.  Anyone else having this problem and are there any
alternatives to the Lancair provided seal?  From the increase of a bit over
$200 per seal to the current $445, for a faulty item, it seems there should
be a better alternative out there.  The book still calls out 20 lbs of
pressure for the door seal and after talking to Justin, he is recommending
12-14 lbs, which is where I currently have adjusted my 5th door seal.
