Spider Vortec Fuel Injector Assembly For GMC Chevy Trucks – 4.3L V6 – FJ503, 12568332

If your Chevy or GMC truck with the 4.3L V6 is running rough or misfiring, the spider injector might be the culprit.

This is a brand new direct replacement assembly from FD.

It fits a bunch of models—just cross-reference FJ503, 12568332, or 19210688.

Includes the fuel injector unit itself, made from plastic and metal.

Two-year warranty included.

It's a common failure on these Vortec engines, so swap it out and get that engine purring again.

Made in China, but built to spec.
