After rotation, could a high deck angle of up to 18 degrees change gravity feed/suction capability of the fuel tank to the engine? I'll bet it's never been tried intentionally.
It most certainly can in some aircraft types, if the fuel quantity in the tanks is too low.
Example,
Years ago, a Bangladesh Biman B707 departed Paya Lebar (Singapore) enroute Kuala Lumpur.
As this was a very short sector, minimal fuel was uplifted SIN with the result that....the airplane rotated, attained a rather nose high attitude, and three engines flamed out due to fuel starvation.
The airplane crashed just off the side of the runway, no fire, minimal injuries to crew and passengers.
I watched it happen, as I was waiting for takeoff in the following SQ 707.
Not a pretty sight.
There was, in the B707-320 AFM, a recommended minimum fuel qualtity in tanks, for takeoff.
As I recall, it was 15,000 pounds.
Biman departed with less, according to reports.
