Pollak 42-159 6-Port Fuel Tank Selector Valve, Supply and Return - Gas or Diesel

The Complete Dual-Tank Conversion Solution for High-Performance Systems

The Pollak 42-159 6-Port Fuel Tank Selector Valve provides everything you need to manage dual fuel tanks in one convenient package. Unlike standalone valves, the 42-159 is a comprehensive kit designed for vehicles requiring a motorized 6-wire system to switch both fuel supply and return lines. This makes it a critical component for modern fuel-injected engines (EFI) as well as heavy-duty diesel applications.

The 42-159 is engineered for precision, ensuring that when you flip the switch, both your fuel source and the return flow are redirected simultaneously. With its high-impact, fuel-resistant construction and integrated Viton seals, it offers a leak-free, long-term solution for trucks, RVs, and specialized vocational vehicles.

Key Features:

• Dual-Line Management: Specifically designed to switch both the "Supply" and "Return" lines for two separate tanks.

• Fuel Versatility: Engineered for full compatibility with gasoline, diesel, and common fuel additives.

• High-Pressure Capability: Designed for use in systems with up to 65 PSI, supporting most modern fuel injection requirements.

• Durable Construction: Features a glass-filled nylon housing and Viton seals for maximum chemical resistance and environmental durability.

• 6-Wire Motorized Operation: Provides a more reliable and positive shift compared to older solenoid-style valves.
