Question How do you make a LS1 fuel gauge read 0-90 ohms????

I got a nasty nate fuel cell and everything all hooked up, and to my suprise the guy before me used a after market gauge to read his fuel level. So i searched for about a hour with no results found yet. I seen how easy it is to go from ls1-lt1 but no lt1-ls1. I was just curious if anyone has ever heard of this being done, or knows where you could buy a circuit for the conversion. Thanks in advance gents!

GM changed the OHM rating of the fuel level sender. I don't know what year the change was made. I do know the 4th gen. sender is 40 to 240 OHM's.

Are you using the 4th gen sender?
I have this vendor bookmarked. I have not used him.

Well the 0-90 was only readying about 1/8 tank at 3/4 full, so i had to do something. I ordered a new unit for the tank from nasty and tryed it last night worked, but full was reading about 3/4 full, so i dunno what to think. Guess i will have to bustout the ohm meter and see if its reading correctly.
