Tony,
I pulled the fuel feed line to the accumulated per the Bentley manual and got ~.5 liters of fuel at 30 seconds. The tape line in the picture is marked at 1 L.
This leads me to believe the fuel pump is a) on its way out or b) there is some kind of blockage between it and the accumulator, which I think would be less likely.
My gauge is the HF one, but for the sake of these tests it’s been removed as a variable due to the perceived slow flow rate (confirmed by my above test).
My system pressure is so low as not to register at all, even after attempting to bleed the gauge. The 50% flow rate would cause that (in my little pea brain, that is).
Am I barking up the right three thinking it’s the fuel pump? I guess I could disconnect the output line AT the pump and test flow rate before buying a new one to confirm.
Thanks,
Joe
