LT1 swap into Chevelle - no fuel pressure

[aarroyo87]

I'm doing my initial start up and I have no fuel pressure. I hear the fuel pump when I turn the key but no pressure at the fuel rail. My fuel system consists of the following:

Spectra EFI fuel tank
1995 Chev Caprice fuel lines
stock fuel pressure regulator
5 gallons of gas in tank

I have a couple ideas of what the problem might be but I have some questions.

Are the Chevrolet nylon fuel lines directional? Meaning fuel can only go a certain direction?

I've heard of Spectra fuel tanks having the fuel pump wire incorrectly. Has any one had this problem and know how to fix it?

Any help or suggestion are appreciated.
