Fuel pumps, how to tell them apart?

[AmericanRicer87]

Did some hunting on the forum, and I can't seem to find any info on how to tell if the fuel pumps your buying from an indiviual are the claimed "supercar gt" pumps and not a random pump. Can anyone answer this or point me in the direction of the info in another thread?

brand new they show up encased in a plastic housing with 2 socks attached. Removed from the housing I'm not sure what they look like...I did a quick google search and the actual housing of the pump appears to be thicker stainless steel material. Cobra pumps are purple and the Focus SVT is green...not sure about Walboro or the Aviator.
