RAYTEN Fuel Spider Injector Kit – Fits Chevy GMC 4.3L V6 (FJ503 / 89060439)
About this item
Got a 4.3L V6 in your Chevy or GMC truck or SUV?
This RAYTEN fuel spider injector kit is a common upgrade.
It's designed to replace the old Central Port Injection (CPI) unit with a more reliable Multiport Fuel Injection (MPFI) setup.
It fits a ton of models from that era – think S10, Blazer, Jimmy, Silverado 1500, Astro vans, and the Sonoma, among others.
The kit comes with the injector assembly itself and the necessary fixing bolt.
It's a direct replacement, so it should bolt right in.
It's made from a mix of plastic and metal, and the connector is black.
It replaces a bunch of part numbers, so cross-reference with FJ503, 12568332, 19210688, or 17113673 to be sure it's the right one for your truck.
