Specs At A Glance

Good To Know

Q: Does this fitting work on all GM LS fuel rails? A: It fits 3/8 inch GM quick connect ports, which cover many LS applications, but some rails use a different size. Confirm your port size before ordering.

Q: Is the clip required for a leak-free seal? A: Yes, the retaining clip locks the quick connect joint so it cannot separate under fuel pressure. Always install the clip fully seated.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
