427 Street -- just remember, if you decide to change out the fittings instead of brushing them clean, or using some sort of poison goo on them, make sure you do a careful job, not a half-ass job.
Those lines (hopefully) see a regular pressure of 60 psi and you might very well surge to a good bit more than that. These are not fuel lines with 6 psi. If you don't do it right, the line will pull out from the fitting and you're likely to burn up your engine before you notice the gauge or the smoke.
