The Carter SX-6346 is constructed from high-quality materials, including corrosion-resistant housing and a durable diaphragm. The pump is also designed to be self-priming, which means it can start pumping fuel as soon as the engine is turned on, even if the fuel level in the tank drops below the pump during operation.

Installation of the Carter SX-6346 is straightforward and can typically be completed in a few hours using standard hand tools. The pump comes with all necessary mounting hardware, as well as detailed installation instructions to make the process as easy as possible.

In summary, the Carter SX-6346 in-tank electric fuel pump is a high-quality, reliable, and durable solution for supplying fuel to the engine of your 1988-1995 GMC C2500 with 4.3L, 5.0L, or 5.7L V8 engines.

With its easy installation process, the Carter SX-6346 is an excellent choice for anyone looking to upgrade their fuel pump system.
