FX20D Fuel line bleed

[jjkittle1]

Does anyone have any experience bleeding the fuel lines of a fx20d? Without bleed screws i cant figure out how the spring buttons work.

Are you familar with your fuel feed pump 129158-52100? Thinking it has a priming lever. Also thinking the push button is just pushed to prime, release once a solid fuel flow is achieved.
