The gtp is 2 speed,pretty sure on my 00 gtp the tank is metal,on the 03 se we have its 100% plastic,as far as I can see they look the same on gtp,gt,se by looking at the top,holes are same,not definite if they interchange but gtp is definate 2 speed cause when its going semi bad you can bend the terminal on the fuse for the pump out and plug it back in and works full speed
