The usual Archer II that I rent was booked up yesterday so I rented a relatively new Archer III, only about 1,400 hrs on it
My question is: In cruise the fuel pressure was at the very bottom of the green band, I would say maybe a millimeter or two above the red low end mark. Switching tanks didn't resolve it. This was with the fuel pump off since that is what is called for in the cruise checklist. I did toggle the pump on and it went back to a typical mid scale indication
What's odd is, on the second leg of the trip the fuel pressure was in the middle of the green band, again at cruise with fuel pump off
The older Archer II that I usually fly stays about mid level, with the fuel pump only having a small effect on fuel pressure. I've never seen the fuel pressure gauge be that low, especially in cruise, in any Pipers I've flown
**So, would you tell the owner, or since it stayed with the green band that's just typical for the newer Archers?** The other peculiarity, when it was near the bottom of the scale it was jumping around a bit. The plane gets flown a couple hours a week so it doesn't sit. And yes I sumped both tanks and the gascolator
