I need to replace my sending unit.

I understood there was two used in 97 Lesabre. I went to the Buick Dealer they told me only one was used. I told him they switched during the yer. He said no.

I went to the Chevrolet Dealer and they told me there was two that year, and mine was "AW2, "W/Out." (Without AW2).

When I look at parts, they list one as, "HEN" "HER" and one as, "CRD".

Which one is without AW2?

Also, I read on some posts where they put in a new sending unit, only to have it not work right. Some have made the gauge swing wild when they go around corners. I don't want to do this again (twice this year as I got a faulty Pump).

I don't want to spend a lot of money. Has anyone put in a few and can share experiences of how it worked, lasted, and what brand?

Thank you,
Chris.
