The best way to get my Epson 9800 going again

When you say ink is not showing in the ink tubes, I’m not sure what you mean. The ink is there in the photos you just shared.

Make sure to screw the o-ring+connector in not too hard. Too hard and no ink will flow.

There are some air in the ink tubes. The air are not moving when i make a ink ChargeIMG_0700

The o-ring+connector are not to tight. See the markings.

I can pull ink from the bottom of the dampers with a syrings. And the ink is coming true. So i think the ink flow is OK.???

This tells me that your dampers are either screwed too tightly or miss-aligned on the inlet spikes or both. Remove and do again.
