fuel guage

ok here it is i have a problem with the fuel guage vibrating really fast
and everybody is saying it is the sending unit well heres where it gets good
I just replaced my fuel pump assembly sending unit and all I still have the same problem I was thinking of checking the wireing maybe there is a problem there.

Any suggestions :)

You may want to remove the I/P and check the bulkhead plug connector at the top center. There may be poor contact. You may also want to check the chassis ground just above and forward of the tank.
