The FAST purge fitting is a small, application-specific fitting for LS3 intake manifolds, intended to provide a clean purge connection point on LS3-style intake plumbing. Sized and shaped for tight installations, it integrates with LS3 intake manifold OEM-style ports to support vapor or purge line routing during engine service or modification where a compact purge fitting is required.
