Fuel related issue on rear engine

[n86121]

The electrical one is fueling the engine, meaning the mechanical one is not.

Mine is turbo, so the fuel adjusts with both altitude and RPM.

My famous drain problem was fuel leaking past the inside of the fuel pump,
back UP the turbo/throttle pressure sense line that goes to throttle body,
into all the intakes.

All said, sounds like a dead mechanical fuel pump.
Prepare for a $1,000 or so OH.
