Gas Tank Anatomy and Components

The 1980 Suzuki GS750 gas tank, like many motorcycles of its era, is a vital component in the fuel delivery system. It’s a crucial part of the motorcycle’s design, ensuring a reliable and efficient fuel supply for the engine. This section delves into the anatomy and components of the 1980 GS750 gas tank, providing a comprehensive understanding of its function and design.

Fuel Cap

The fuel cap is a critical component of the gas tank, responsible for sealing the tank and preventing fuel spillage. It’s typically made of metal or plastic, and its design often includes a locking mechanism to prevent unauthorized access. The fuel cap on the 1980 GS750 is designed to securely seal the tank opening, ensuring that fuel remains contained within the tank and preventing evaporation.

Vent Hose

The vent hose plays a crucial role in maintaining proper pressure within the gas tank. It’s a small, flexible hose connected to the tank’s vent, allowing air to enter or escape the tank as needed. This helps prevent the tank from collapsing or becoming over-pressurized during temperature fluctuations or changes in altitude.

Fuel Gauge Sender Unit

The fuel gauge sender unit, located inside the gas tank, provides a reading to the fuel gauge on the instrument panel. It typically consists of a float connected to a potentiometer. As the fuel level changes, the float moves, altering the resistance in the potentiometer.

This change in resistance is then interpreted by the fuel gauge, displaying the current fuel level.

Fuel Lines

Fuel lines, made of durable rubber or plastic, connect the gas tank to the fuel petcock and the carburetor. They are responsible for transporting fuel from the tank to the engine, ensuring a constant supply of fuel for combustion.

Petcock

The petcock, also known as a fuel valve, controls the flow of fuel from the gas tank to the engine. It’s typically a simple valve with a lever or button that can be switched between “on,” “off,” and “reserve” positions.

The petcock on the 1980 GS750 allows the rider to control the fuel flow, ensuring that fuel reaches the engine only when needed.

Common Gas Tank Issues and Repairs

The 1980 Suzuki GS750, like many motorcycles of its era, is prone to certain gas tank issues. These problems can range from minor annoyances to major headaches, affecting performance, reliability, and even safety. Understanding these common issues and how to address them is crucial for keeping your classic GS750 in top condition.

Rust and Corrosion

Rust and corrosion are common enemies of older motorcycle gas tanks. The inside of the tank can be exposed to moisture and condensation, which, in combination with the presence of oxygen, can lead to the formation of rust. Rust can impede fuel flow, clog fuel lines, and contaminate the fuel, leading to engine problems.

Visual Inspection:The first step is to visually inspect the inside of the tank. If you see rust, it’s time to take action.
Tank Cleaning:Several methods can be used to clean a rusty tank. One common approach involves using a commercial tank cleaning solution. These solutions are typically acidic and can effectively dissolve rust. However, it is crucial to follow the manufacturer’s instructions carefully, as these solutions can be corrosive.
Tank Sealing:Once the tank is clean, it’s important to seal it to prevent further rust formation. This can be done using a tank sealer, which is a specialized coating that forms a protective barrier against moisture and oxygen.

Leaks and Cracks

Cracks or leaks in the gas tank can be caused by various factors, including age, impact damage, or improper handling. Fuel leaks can be dangerous, posing a fire hazard.

Identifying Leaks:To identify leaks, carefully inspect the tank for any visible cracks or holes. You can also use a soapy water solution to check for leaks.
Repairing Small Leaks:Small leaks can sometimes be repaired with a tank sealant. This sealant is applied to the leak and allowed to cure, forming a durable seal.
Major Damage:For significant cracks or damage, a professional repair may be necessary. A qualified technician can weld or braze the tank, restoring its integrity.

Fuel Gauge Malfunction

A malfunctioning fuel gauge can be frustrating, as it makes it difficult to track fuel levels and plan refueling stops.

Check the Sending Unit:The fuel gauge sending unit is a component inside the tank that sends a signal to the gauge on the instrument panel. It can fail due to corrosion, damage, or simply age. Inspect the sending unit for corrosion or damage.
Gauge Testing:Test the gauge by disconnecting the sending unit and grounding the wire. If the gauge moves to full, the sending unit is likely faulty.
Replacement:If the sending unit is faulty, it may need to be replaced.

Petcock Issues

The petcock, which controls fuel flow from the tank, can also cause problems.

Petcock Cleaning:Over time, the petcock can become clogged with debris or rust. Cleaning the petcock can restore its proper function.
Petcock Replacement:If the petcock is severely damaged or worn, it may need to be replaced.

Troubleshooting Common Gas Tank Issues

Once you understand the anatomy of your GS750’s gas tank, you’re equipped to tackle common issues. By identifying the source of the problem, you can effectively address it.

Identifying and Addressing Leaks

Leaks are a frequent concern with gas tanks. These leaks can occur due to various reasons, including corrosion, damage, or improper sealing. To identify the source of the leak, you can use a visual inspection, a pressure test, or a leak detection dye.

Visual Inspection:A visual inspection can help identify obvious signs of damage or corrosion. Look for cracks, dents, rust, or holes in the tank.
Pressure Test:A pressure test involves pressurizing the tank with air and checking for leaks. This method is more sensitive than a visual inspection and can detect even small leaks.
Leak Detection Dye:A leak detection dye is a specialized solution that can be added to the gas tank. If there is a leak, the dye will leak out, making it easier to identify the location.

Once you’ve identified the source of the leak, you can address it accordingly. Small leaks can sometimes be repaired with a sealant, while larger leaks may require a replacement tank or professional repair.

Addressing Rust and Corrosion

Rust and corrosion are common problems that can affect the gas tank, particularly if it’s not properly maintained. Rust can form inside the tank due to moisture or condensation, leading to clogging and fuel flow issues.

Prevention:Regular maintenance is crucial to prevent rust. This includes using a fuel stabilizer to prevent condensation and ensuring the tank is kept clean and dry.
Treatment:If rust has already formed, you can try to remove it with a chemical cleaner or by using a specialized rust removal process.

For severe cases of rust or corrosion, you may need to replace the gas tank or have it professionally restored.

Addressing Fuel Gauge Issues

Fuel gauge problems can be frustrating, leaving you unsure about your fuel level. These issues can arise from a faulty fuel sender unit, a broken wire, or a malfunctioning gauge itself.

Fuel Sender Unit:The fuel sender unit is responsible for sending a signal to the gauge, indicating the fuel level. A faulty sender unit can lead to inaccurate readings.
Wiring:Broken or corroded wires can also interrupt the signal from the sender unit to the gauge.
Gauge:The fuel gauge itself can malfunction, leading to inaccurate readings.

To diagnose fuel gauge problems, you can check the wiring, test the sender unit, and replace the gauge if necessary.

Addressing Fuel Flow Issues

Fuel flow issues can prevent the engine from receiving fuel, leading to starting problems or engine stalling. These issues can stem from a clogged fuel filter, a blocked fuel line, or a faulty fuel pump.

Fuel Filter:The fuel filter traps debris and impurities from the fuel, preventing them from reaching the engine. A clogged fuel filter can restrict fuel flow.
Fuel Line:Fuel lines can become blocked by debris or corrosion, restricting fuel flow.
Fuel Pump:The fuel pump is responsible for pushing fuel from the tank to the engine. A faulty fuel pump can fail to deliver sufficient fuel pressure.

To address fuel flow issues, you can inspect and replace the fuel filter, check the fuel lines for blockages, and test the fuel pump for proper operation.
