1991 K5 - Need Part Number for Fuel Tank Sending Unit

[2Dogs]

Hello All,
I am 90% sure I have the 25 gallon tank (RPO code list below). My local part store only shows sending units for the 31 gallon tank and I have lost my part number list I have used over the years: I am requesting a part number/brand for my tank if anyone has it documented.

I will take a pic of the tank (in truck) this weekend to help verify the size of my tank.

Thanks for the help!

Dunno if this helps. but this is the spare I'm ordering to carry around. It's for the 25 gallon tank.

You can measure the tank's height to determine which you have. The ~25 gallon is 10 3/4" deep, versus the ~31 gallon is 12 3/4".

I will be looking at it today - measure and take pics, thanks!

OK - I measured and came up with ~12.5" so it looks like 31 gallon.... So my memory might not be as good anymore
