turn the fuel pump off at 300 feet ie the time you need that redundancy the most, because "that's what my instructor told me to do" rather than read the POH or even consider what the electric pump is there for.
Apparently it is also 'Company policy' to have a 'new' electric pump fitted at the start of every Soaring season.
I have no argument with that.

Not saying this is the cause, but A few Years ago, we changed the engine in a PA28-181, the overhauled exchange engine had been supplied by the operator. (purchased direct by the operator) from a well know engine overhaul shop in NSW.
During the overhaul the shop had "neglected" to install the plunger that actuates the engine driven fuel pump. With the wing tanks full, the engine ran fine during ground runs, even though the fuel pressure was reading zero... until it was taxied to a certain place where the attitude of the aircraft on the ramp precluded the flow of fuel to the carby when the engine stopped.
Needless to say the rear case had to come off and the part installed.
Interesting thing the overhaul shop had provided ground test reports that included the fuel pressure at all RPM's

Apologies for what is a bit of thread drift, on my occasion the engine was a bit bigger (P&W R 2000) as was the engine overhauler, who shall remain nameless, but it was not QF.
Come the day, said engine was hung on the wing of a DC-4, and out they went for an engine run.
The numbers were a bit off, so back they came for a change of plugs.
Next time, still the same "bit off", so back they came and this time they did a compression check. Low and behold, there was nil compression on one jug.
So, off came the rocker caps, but everything looked fine there, so off came the jug, whereupon the cause of the lack of compression was was very obvious.
There was a complete absence of a piston and link rod in said cylinder.
Despite the test cell run sheets having all the numbers within limits-just!!
I suppose you could say that, at least they got thirteen out of fourteen right, so it was only one fourteenth wrong, which was about average for said org., which went out of the big engine business not long after.
Tootle pip!!
