Filling Up To Tabs...How Much Fuel Are In Tanks?

in General Discussion
I have a Piper Arrow with 77 gallons total fuel capacity, 72 usable. 2 1/2 gallons on each tank is unusable.
If I fill up to tabs, how many gallons do I have?

    I too have an Arrow with the 77 gallon tanks.
    In the manual which I have, in Section 7.13 it states that the USABLE capacity to the bottom of the indicator tab is 25 gallons.

    Hope this helps.

    When I saw the original post I almost answered with what I had been told. I decided however it would be best to refer to the POH, but I never could find a reference to the capacity with fuel at the bottom of the tabs in my POH. I even looked in the maintenance manual I have for my 1977 Arrow III but could not find a reference to the tabs. I had always heard that the bottom of the tabs was 25 useable per tank but I also found internet references to the bottom of the tabs being 22.5 useable.
    I will recheck my POH and specifically the reference you gave to see if I can find it.

    I got one of those 'fuel straws' made for my tanks. The guy on ebay('fuel stick' or similar) sells them, may have one for your model. I can see exactly how many gallons are in each tank, may not be essential, but helps a lot when figuring weight & range available. I use it often.

    I have looked through my entire POH and it says nothing about the fuel level at the tabs. As for fuel straws, I would love to try that but have never been able to find one calibrated for the Arrow III. Only option is to purchase a generic one and calibrate it my self.

    Thanks to all who answered. It is appreciated. I attempted to look up "fuel straws" on EBAY with no luck. Is there another source for these fuel straws?

    Thanks again !!

    My source may not be on ebay anymore. He may not have a calibrated 'straw' for the Arrow either. He is dipstikfuelgauge.com out of Utah. He has a site that has some info.
