The connectors are not the same between them, however after all is said and done with getting it setup, you'd be better off going with a return style system with a set of Walbro pumps depending on how much power you're trying to support. Even the GT350 pumps tend to make out quickly just like the GT ones. If you have any questions about any of those setups, I'm always available. Lethalperformance.comDoes the GT fuel pump connector need to be modified? I have search our forum and no one seems to give a clear answer.
