Product Details

This Autobest fuel pump and sender assembly is engineered for direct-fit replacement on select 1994-1997 Chevrolet and GMC applications, including C1500, C2500, C3500, K1500, K2500, and K3500 models, plus Suburban variants with the listed connector and tank configurations. The F2633A part number is also referenced in the aftermarket under several cross-reference numbers for the same application. Autobest F2633A is built with tested components and is supplied as a complete pump-and-sender solution for restoring fuel delivery and tank level reporting.

Autobest’s Fuel Pump and Sender Assembly line focuses on complete replacement units that simplify service on aging fuel systems. For owners maintaining a Chevrolet C1500 or GMC K1500, this product line targets the common need to replace both the pump and sender together rather than servicing them separately.

What It Helps Fix

• Hard starting caused by weak or failing fuel pressure
• Inaccurate or intermittent fuel gauge readings
• Engine hesitation from inconsistent fuel delivery
• No-start conditions related to an in-tank pump failure
• Fuel system service needs on high-mileage GM trucks and SUVs

Installation Notes

• Fits select 1994-1997 Chevrolet and GMC trucks and Suburban models; verify connector style, tank configuration, and notes before ordering.
• Applications include 3-pin connector and 4-tube-port configurations depending on vehicle listing.
• Use the included strainer and tank seal during installation.
• Confirm outlet size, inlet style, and sender resistance specifications against the original unit.
