HP fuel pumps on T7
Please can someone help me with the type of HP fuel pumps referred to; centrifical or positive displaced (lobe) type.
Thanks
"The gear-type HP pump gets fuel from the:
* LP fuel filter
* Servo return
* FMU bypass.
The HP pump supplies fuel to the FMU and servo fuel to engine
components."
