The best SBC fuel line from pump to carburetor depends on the vehicle, engine, carburetor, and whether you want a formed steel line or flexible hose. The listings below include vehicle-specific steel options for select Chevy and GMC applications, a general replacement line, and a universal braided hose kit. Match the listed year and configuration to your vehicle before ordering; these products are not interchangeable just because they serve the same purpose.
| Product | Best For | Line Type |
|---|---|---|
| Inline Tube General Pump To Carb Line | Buyers checking a broad year range | Formed steel |
| Day Muffler and Brakes C10 Pump-Carb Line | Specified 1973–1980 truck applications | Formed steel |
| Inline Tube Corvette 350 Line | Specified 1977–1981 Corvette configuration | Formed steel |
| Inline Tube Truck/SUV 350 Line | Specified 1973–1980 2WD applications | Formed steel |
| CarBole 6AN Braided Hose Kit | Custom or universal hose needs | Flexible braided hose |
Inline Tube General Pump To Carb Line
This formed line is listed for 1955–1988 General applications. Its description specifies a 90-degree tube at one end, a straight end, and a two-inch center section. Inline Tube says the line is CNC manufactured, with factory-correct bends, fittings, flares, and protective wrap where equipped. It is made from original-equipment-grade tin-coated steel tubing.
Best for: Buyers whose vehicle falls within the stated year range and who are verifying that the listed line configuration matches their setup. It was selected as a broad-range formed-steel option. Limitation: “General” does not identify a specific vehicle or engine combination, so confirm the application and end details before purchase.
Day Muffler C10 Pump-Carb Fuel Line
This listing specifies a pump-to-carburetor line for 1973–1980 Chevrolet C10 and C20 and GMC C15/C1500 and C25/C2500 models. The stated engine and carburetor configuration is a 5.7L, 350 CID V8 with a 4-barrel Quadra-Jet. The listed part number is TPC7901OM.
Best for: Owners whose truck, engine, and Quadra-Jet configuration match the listed application. Its vehicle-specific details make it a clearer choice than a generic line for those trucks. Limitation: The listing does not describe tubing material or detailed bends, so verify those details if they matter to your installation.
Inline Tube Corvette 350 Steel Line
This 3/8-inch pump-to-carb line is described for 1977–1981 Chevrolet Corvette models with a 350 CID engine and Quadrajet standard engine configuration. Inline Tube lists CNC manufacturing, factory-correct bends, fittings, flares, and protective wrap where equipped. The tubing is original-equipment-grade tin-coated steel.
Best for: Buyers restoring or maintaining a Corvette that matches the stated years and engine configuration. The defined vehicle and engine application makes it more targeted than a general-purpose line. Limitation: It is not presented as a universal SBC line; do not assume it fits a different year or carburetor setup.
Inline Tube 1973–1980 Truck/SUV Line
This one-piece, 3/8-inch pump-to-carb line is listed for 1973–1980 Chevrolet and GMC truck and SUV applications with a 2WD 350 CID engine and 4-barrel carburetor. The description identifies original-equipment-grade tin-coated steel and lists part references 32-3646 and TPC7901OM.
Best for: Buyers whose vehicle matches the stated year, 2WD, engine, and carburetor details and who want a one-piece formed line. It was selected for its specific truck/SUV application. Limitation: The listing’s stated configuration is specific; confirm vehicle details rather than relying on the 350 engine designation alone.
CarBole 6AN Braided Fuel Hose Kit
This kit includes a three-foot, 3/8-inch inner-diameter stainless-steel-braided CPE hose and two AN6 swivel hose ends. The listing describes use with fuel and several other fluids. It gives a maximum working pressure of 1,000 psi, a burst pressure of 6,000 psi, and a working temperature range of -40°F to 257°F.
Best for: Buyers planning a custom hose-based fuel-line setup who need the supplied AN6 ends. Limitation: This is not a pre-bent vehicle-specific steel line. The listing advises checking pressure and temperature suitability, and buyers must confirm that the hose length and fittings suit their application.
Buying Guide: Choosing An SBC Pump-To-Carb Fuel Line
Does the line match your vehicle and carburetor?
Start with the vehicle year, make, model, engine displacement, drivetrain, and carburetor type. A 350 CID small-block alone does not establish fitment. Compare each item’s complete application details, especially when choosing among the Corvette and truck lines.
Should you choose formed steel or braided hose?
Formed steel lines are the vehicle-specific style represented by the Inline Tube products and the Day Muffler line. They are defined by their bends, ends, and application. Braided hose is the more flexible option in this selection, but it requires checking hose length, fittings, routing, and stated operating limits for your setup.
What dimensions and ends should you verify?
Check the line diameter, end fittings, flares, bends, and connection points against your existing installation or reliable vehicle-specific information. The listings identify 3/8-inch tubing or hose for several products, but that measurement by itself does not confirm a complete match.
When is a universal hose kit the better choice?
Choose a universal hose kit when a custom flexible line is appropriate and its length, AN6 ends, and operating range meet the application’s requirements. Choose a formed replacement line when the vehicle-specific listing matches and its described configuration suits the installation.
Frequently Asked Questions
What does pump-to-carb fuel line mean?
It refers to the line that carries fuel between the fuel pump and the carburetor. The correct replacement depends on the vehicle and fuel-system configuration.
Will any 3/8-inch line fit an SBC?
No. Diameter is only one specification. Vehicle fitment, routing, fittings, flares, and carburetor configuration also need to match.
Is the Corvette line interchangeable with the truck line?
The listings specify different vehicle applications. Do not treat them as interchangeable unless the application details for your vehicle confirm a match.
Can the braided hose kit replace a formed steel line?
The kit is described as a universal hose with AN6 ends, not as a direct-fit formed replacement. Confirm that its fittings, length, and operating limits suit the planned installation.
