Does anyone happen to know what the part number for the gauge sender is? I need the one in the cylinder head. I've been looking online and have only come across the one in the water pump. TIA. BTW, this is for a 97 LT1 if it matters.

 

Try 25037332

Listed on my part numbers page. I only recommend the ACDelco/GM part.
