Product Overview
The Rotary13B1 fuel injector clip is engineered for top‑feed fuel injector applications where reliability and durability are paramount. Constructed from high‑grade stainless steel, the clip resists corrosion and withstands the harsh environment of the engine bay. It features a 3‑inch threaded inlet connection and a FNPT (Fuel Needle Pipe Thread) outlet, matching the EV1 specification commonly found in many modern vehicles. Each pack includes four precision‑cut pieces, allowing you to replace multiple pigtails or keep spares on hand. The compact dimensions (2.7 x 2.3 x 0.4 inches) and lightweight design (0.634 ounces) make installation straightforward without adding bulk.

Usage
Designed for automotive technicians, performance tuners, and DIY car owners, this clip is ideal for replacing worn or brittle EV1‑type fuel injector pigtails. It fits seamlessly into existing harnesses on gasoline and diesel engines that use top‑feed injector setups. The 3‑inch inlet threads into the injector body, while the FNPT outlet connects to the fuel rail, providing a secure, leak‑free seal.
