Fuel rail pressure test port size?
If I needed to put a hose on the fuel rail pressure test port (I'll be taking out the schrader valve), what ID size do I need? Like 3/8" ?
I'm just going to run a hose like 10 ft into the gas tank of a rental car to get all the old gas out of my Trans Am that's been sitting for several months by turning the key on and using the in tank pump.
Then I'm going to put a gallon of new gas in the tank and doing the same to flush it until the entire fuel system is bone dry. For storage.
Thanks!

You can use an open end wrench to roughly determine the diameter of the test port.
This is an interesting method for draining and flushing.

Thanks! I still may do what Drew suggested and just unscrew the fitting on the front of the engine where the fuel goes into the rail. It's the top one of the 2 I believe that is the feed, the bottom the return, right guys?
Somehow while I was back in the US the past few weeks, I came back and my brand new Optima that I bought last October before shipping the car was at 0.01 volts! Turns out something got messed up with the car just parked that caused the switch on my rear view mirror to short, leaving both map lights on no matter what position the switch was in :/ I had to just unplug it.
So for the past few days I'm been trying to save my Optima from the afterlife. I don't have a 2nd battery and no fancy AGM chargers (Like a CTEK) on the island so I used another method and I'm in the home stretch, as of this morning, my battery tender now detects the battery and is charging it (confirmed by multimeter of course).
Once the battery is recovered and I can start the engine, I'm going to change the oil and do the fuel line thing. I need to get the car into the seatrain in the next week so I can come back to the US for work again.
