Which is standard LS pressure.

thanks, I researched the Corvette one like a year ago when I first got the engine, but honestly been so distracted with other projects and forgot all of my research, thank you all for your help, Speedway makes this nice unit that integrated -6AN fittings on to it so no need for adapters, I ordered one today off of Amazon, but I still can't find what the stock one looks like on our trucks for 2004 5.3L
