Question about 1999 GMC Sierra
On most vehicles you can only place the max amount of fuel in the vehicle to the point the fuel nozzle shuts off.when you put more into it it causes a temp.flux in the floater causing it to go to the bottom until there is air back in the tank. the floater has to have so much air to float. sort of like your lungs when you exhale all the air your lungs will collapse.

My 1999 GMC Sierra did the same thing. Fuel pump went out shortly thereafter.
