Fuel pump & sending unit

Will a fuel sending unit and pump for a 20 gallon tank fit and work in a 15 gallon tank?

The fifteen gallon tank is actually a 20 gallon tank with an extended fill tube in it preventing you from using the top five gallons. Do a search for Wrangler Gas Tank mod and you will find the steps to remove the extended fill tube and get the full 20 gallon use of your tank.

Yes the 20 gallon sending unit will work, but until you do the mod, it should only register 3/4 when you fill to 15 gallons.

This ^ is correct unless you have the older 15 gal metal tank, those are a different size than the 20/15 gal plastic tank.
