To be perfectly honest I have no idea if they should be the same, but I'm sure someone here knows. I'd make sure before you buy anything, although I've bought from Advance, I can't vouch for them.
They all use the same pump and fuel pump driver module. The fpdm regulates the voltage so it pumps the right pressure. I hope you can get one for cheeper then those prices above. Thats hella expensive. If not get a svt focus pump or find one on ebay. Or find someone with a blower who has their old one sitting around.
