The best dual tank selector valve depends on the vehicle’s port layout, wiring, and fuel-line configuration. For select classic Chevy and GMC trucks, the Daposhac 467513 is a specific six-port replacement; for a complete six-port setup, the APSG kit includes wiring and installation components. The JDMSPEED and SMP/APSG options are three-port valves for main-and-auxiliary systems without fuel return lines. Standard Motor Products’ FV1T is another option, but its listed details provide limited fitment information.
| Product | Configuration | Best For |
|---|---|---|
| Daposhac 467513 | Six-port, single-wire | Select 1970s Chevy/GMC trucks |
| Standard Motor Products FV1T | Fuel selector valve; details limited | Buyers matching a known FV1T application |
| JDMSPEED | Three-port, 12-volt | Systems without fuel return lines |
| APSG six-port kit | Six-port kit | Buyers needing included wiring and hardware |
| SMP/APSG three-port kit | Three-port, 12-volt | Main-and-auxiliary systems with 5/16-inch hose barbs |
Daposhac 467513 Six-Port Selector Valve
This valve is best for owners of select classic Chevy and GMC pickup trucks that use an original six-port, single-wire selector valve. It is designed to replace OE number 467513 and is described for compatible dual-tank systems from the 1970s.
The listed fitment includes select 1975–1980 Chevrolet and GMC C/K pickups. The product description calls out a restriction for 1980 models: it excludes 250 and 292 engines. Verify the original valve configuration and vehicle application before ordering; model year alone does not confirm fitment.
Standard Motor Products FV1T Fuel Selector Valve
The FV1T is best for buyers who have confirmed that this specific part number matches their existing fuel-selector setup. The listing identifies it as a Standard Motor Products T-Series fuel valve and solenoid, with part number FV1T.
The supplied product details do not specify port count, vehicle fitment, voltage, or included installation hardware. That makes application verification especially important. Choose this option when you can match the FV1T number to a reliable parts reference or the vehicle’s original component, rather than relying on the general phrase “dual tank selector valve.”
JDMSPEED Three-Port Switching Valve
This valve is best for a 12-volt vehicle with one main tank and one auxiliary tank, provided the system has no fuel return lines. Its listed application describes a three-port main-and-auxiliary arrangement, making it a different choice from a six-port valve intended for other plumbing layouts.
Choose it if the vehicle’s fuel system matches those stated conditions. Avoid it if the system uses return lines or requires six ports; the product details do not claim compatibility with those configurations. Check the existing valve and fuel-line routing before buying.
APSG Six-Port Dual Tank Valve Kit
The APSG kit is best for buyers who need a six-port dual-tank valve along with related installation components. The listing describes a gas-or-diesel kit with a harness plug, toggle switch, wire connectors, clamps, and instructions. It also provides cross-references including Pollak 42-203, 42-159, U7001, and 14029228.
Compare the valve’s port arrangement and reference numbers with the vehicle’s original setup before purchase. Although the listing describes broad GM and Ford compatibility, those vehicle makes alone do not establish fitment for every model or fuel system.
SMP/APSG Three-Port Valve Kit
This kit is best for a 12-volt system with one main tank and one auxiliary tank that uses a three-port, two-inlet/one-outlet layout. The listed ports have 5/16-inch hose barbs. Included components are three stainless-steel hose clamps, 12 feet of 10-gauge wire, an inline fuse and holder, and butt and eyelet connectors.
It is a more complete option than a valve-only purchase when the supplied wiring and connectors suit the installation. Check hose size and port layout first. The listing describes a three-port arrangement, so choose a different configuration if the vehicle requires six ports.
Buying Guide: How To Choose A Dual Tank Selector Valve
How many ports does the system need?
Count the ports on the existing valve and compare them with the replacement’s stated configuration. A three-port valve and a six-port valve are not interchangeable based on the fact that both serve dual-tank systems. The plumbing arrangement determines which design is appropriate.
Does the vehicle use fuel return lines?
Check the fuel-system layout before selecting a valve. The JDMSPEED listing specifically describes vehicles without fuel return lines. Do not assume a valve for a no-return system will work in a return-line system unless the application information confirms it.
What should you verify for a classic truck?
Confirm the OE number, model year, engine-related restrictions, wire configuration, and original valve style. For the Daposhac 467513, the stated application is limited to select Chevy/GMC models, and the listing excludes certain 1980 engine combinations. Match the part to the existing component, not just the truck’s name.
Is a kit or a valve-only part better?
A kit can be useful when its switch, wiring, connectors, clamps, or instructions match the planned installation. A valve-only part may suit a direct replacement when the existing supporting hardware is usable. Compare included components with what the vehicle actually needs.
Frequently Asked Questions
Can a three-port valve replace a six-port valve?
Not based on the available product details. They have different port configurations. Match the replacement to the vehicle’s fuel-line layout and original valve.
What does OE number 467513 indicate?
It is the replacement reference listed for the Daposhac valve. Confirm that the vehicle uses this part number and the matching six-port, single-wire style.
Does every dual-tank system use a selector valve?
The products here are described for switching between main and auxiliary or dual fuel tanks. The correct valve depends on the system’s plumbing and electrical configuration.
What should I check before ordering?
Verify port count, wiring, voltage where specified, fuel return-line presence, hose size, OE or cross-reference number, and vehicle-specific fitment.
