No fuel 72 240Z, HELP!

Started to get a loss of fuel stall at high rpm with full throttle 3 weeks ago and assumed mechanical pump was going bad. I've been out of country for 2 weeks so when I returned I replace the fuel pump and get no fire at all. There is at least 3 gal in the tank and I have cleared all the lines but when I crank it over there's no fuel flowing into the filter and when I pulled the fuel line from the carb and crank I get no fuel as well. Grabbed the old pump and she work just fine by hand pump as well??? Why can't I pull fuel from the tank? Is it possible the cam lobe to actuate the pump lever is screwed up? Wouldn't that have been more catastrophic? I'm at a total loss. I could run the electric pump with mechanical omit but I'm not convinced that's the right choice until I know why I can't pull or push fuel. Any thoughts?

Well I got her to run. I don't know why but the fuel line from tank to filter ran dry and the mechanical pump could not prime it. I ran some extra fuel line from a gas can to the pump and she fired right up..... After it ran for a bit the fuel overflow,return pipe primed the fuel rails and it worked just fine when hooked back up. Never had this happen before. Really weird. Thanks for the reply. Jim
