Ok put rebuilt carter w/o on hooked up fuel lines and started crankong engine over. My fuel filter is translucent so I would becablecto see fuel moving through.
No such luck. Took pump off and there seems to be pressure coming from output side but no suction from intake side. Kinda baffled at this point. Worked fine before rebuild of w/o. Except had to choke her very hard to keep running. Could both problems have surfaced at the same time or am I overlooking a step or .....?

I see only steel fuel line. Is there a short rubber tube from the frame hardline to the pump?

Yes. There is rubber tubing on each side of fuel filter and between hard line from tank and line to pump

If those rubber to steel transitions involve straight-cut steel you may be sucking air at any or all of the connections. A single-clamped, straight rubber to straight steel tube connection will immediately be a probable air infiltration source because when the clamp is tightened, the rubber tends to “bunch up” leaving very narrow longitudinal gaps in the connection. If you cannot use a mechanical connection, I strongly urge you to install additional clamps. One more at each end of the rubber. As well, the connection from the frame-mounted steel fuel line directly to the pump should definitely be a rubber tube with mechanical connections. The short steel inlet line is an arm that vibrates, thus weakening the connections.

Thanks I will check and add extra clamps.

Ordered new glass top fuel pump and all new,fuel lines. Should be here tomorrow. Drained the fuel tank of all the 93 octane gas. Switching to lowtest 87 octane. Am still gonna use the ethenol treatment.
Hope this cures the problem. Was planning on going to the Bantam jeep festival this coming weekend.

Ok. Parts got sent to wrong address and then back to seller. Finally received them today. Missed the Bantam jeep fest. So no instructions with the pump or lines. Was wondering if there is anything need to worry about or prep for. After lines are hooked up is there a priming procedure? Any hints or help will be greatly appreciated. Thanks in advance

No priming procedure. Gravity will take care of that. Routing the line around the master cylinder and the steering box will cause curse words to appear out of nowhere. Good luck!
