[Rhodes22-list] My other "boat"

[Brad Haslett]

Philip,

It ran fine for 150 hrs after the overhaul and the first two legs for me.
Here is another "curveball" that I'll never have the answer to: the overhaul
shop was busted by the FAA a few months before this pump was re-worked for
"discrepancies".  That could mean paperwork or it could mean shoddy
workmanship.  They sent the pump back with another "overhaul" at no charge -
I'm sure to keep me quiet.  All logic would dictate that the original
problem I experienced would lead one to believe that the engine pump
failed.  We'll see.

These types of problems are the most difficult to solve.  My wife has been
bitching at me for months to fix the electric door locks on her Honda
Accord.  Last night they worked fine and I asked, "what's the big issue,
they look like they work fine to me".

"They only work when it is cold and wet".

"So only drive when it is cold or wet!"  You can imagine how well that went
over.

This fuel issue may well be something similar.  It may only happen rarely
when the right combination of environmental circumstances occur.  I'll use
the electric back-up for takeoff and landing and see if it happens again.

Brad
