Well I recently put a new inline fuel pump in my 1982 280zx 2+2. I put 4 gallons of fuel in it and tried to crank it over it's getting fuel to fuel pump but not past the fuel damper. So my question is what are my options is it possible I'm not getting enough pressure in the tank could the fuel damper be bad if so could I just remove it and run a rubber fuel line straight from the pump to the aluminum fuel lines and cut it completely out. Car sat for 10 years so my thinking is I need to replace entire fuel lines. I cleaned had tank and sending unit with paint thinner put new fuel pump and filter on it but still no fuel to rails any help be greatly appreciated

Just an FYI 10 years is a long time for those injectors.  I would also verify you can hear each one clicking. I had a 300ZX I just went through that was sitting for 2 years. None of the I jectors would fire. I had to clean them one by one and lube and apply voltage on and off until they freed. 

If i recall right, there was a warning in the user manual of the 280zx that if you run it dry the tank has to be filled for more than 3/4 !  otherwise the pump will not get the fuel to the injectors.. my two cents..

The standard pump has a check valve. What type of pump are you using? Original or aftermarket?

The new eyelets show that it's possible that you have it wired backward.  If you look very closely I think that you'll find a + and a - molded in to the ceramic (or plastic.  Whatever the white material is) where the wire terminal studs are.  The green wire goes to +.

I'll try flipping them

I meant to take your advice sooner and double check but got busy with life

Ok so zed head I swapped the wires around and now my passenger side blinker started going nuts and the pump bogged down??? What's up with that

It's just two wires, and a DC motor.  Can't really screw that up beyond accidentally shorting the power wire and blowing a fuse, or connecting the wires backward.  Those are, really, about the only two things that can go wrong.

Sorry.  Keep it simple.  You might have accidentally bumped some other wires or discovered an already existing problem.
