Fuel Pump and Sender Assembly for Auxiliary Tanks

The Hella 358302581 fuel pump and sender assembly combines electric fuel delivery and fuel level monitoring in one integrated unit. It is built for vehicles with an auxiliary fuel tank and supports steady fuel supply while providing accurate tank level readings.

For Chevrolet and GMC truck applications, this Hella fuel pump and sender assembly helps streamline replacement by combining the pump and sender into a single assembly. The Hella 358302581 is a practical OE-style service part for auxiliary tank systems that require electric operation and fine filtration.

• Electric operating mode for fuel transfer from the tank to the engine
• Integrated fuel sender unit for accurate fuel level reporting
• Includes fine filter support
• Built for auxiliary fuel tank applications
• Cross-references 25090837 and AFE3630S for the same application

Detailed Description

This fuel pump and sender assembly is made for select Chevrolet and GMC models from 1985-1991, including Chevrolet S10, R10, R20, R30, R2500, R3500, V10, V20, V30, V3500 and GMC R1500, R2500, R3500, V1500, V2500, V3500 applications listed for auxiliary fuel tanks. It delivers fuel electrically while the sender reports fuel level to the gauge system, helping maintain consistent operation in vehicles that rely on a separate tank setup. The Hella 358302581 is a direct-fit service solution for these truck platforms where both fuel delivery and level sensing are handled by one assembly.

What It Helps Solve

• Inaccurate fuel gauge readings from a worn sender
• Weak or inconsistent fuel delivery from the auxiliary tank
• Hard starting caused by fuel supply issues
• Intermittent fuel starvation under load
• Service delays from replacing pump and sender separately
