So,I decided to try this

I came across this article on Allpar.com on swapping out the crappy voltage regulator on the dash cluster of my Duster for a Solid State TO-220 5v regulator and decided to try it out on a spare cluster I have.

I will be putting it back together and see how it goes because last time I used this cluster even with a brand new fuel gauge sending unit and ground strap,the gauge was still acting up.
I will post the results later on.
