Tech Insight
When installing NPT to AN adapters:
Apply thread sealant to the NPT side only.
Never apply sealant to the AN flare surface.
Do not over-tighten — NPT threads seal via taper interference.
Upgrading to -8 AN plumbing is common in boosted LS builds, high-horsepower race applications, and off-road rigs where consistent fuel volume under load is critical.
