Have you checked the tipover sensor yet? When you swapped tanks did you also swap the mounting bracket? Did you swap tip over switches as well? It could be upside down.

Ok, so I changed out the turn over switch with my Original one.
She fires up now!
However, refuses to rev over 1.8 k or so. It'll idle all day long, just wont ever go above 2k.
I charged the battery, thought mabey the fuel pump wasnt getting enough juice....
I'm not sure what to start doing, I KNOW the fuel pump is not the problem, I just put in a new one. and then swapped with the old (still functional one) and they react identical. so whatever feeds the signal to my fuel pump...is what the problem is. And I have no idea how to fix it.
