What You'll Learn
Worm gear clamps vs. squeeze-style clamps
When clamping a fuel line, there are several types of clamps to choose from, each with its own advantages and disadvantages. Two of the most common types are worm gear clamps and squeeze-style clamps, also known as spring clamps.
Worm gear clamps are metal band clamps with a helical-threaded screw, also known as a captive screw, that allows you to tighten and loosen the clamp's grip. They are high-torque clamps that prevent hose connections from slacking and leaking. One advantage of worm gear clamps is that they can be tightened as much as needed, as long as the clamp doesn't become deformed. They also come in a variety of sizes and are available in stainless steel with a zinc coating for increased resistance to corrosion. However, one of the biggest criticisms of worm gear clamps is that they can loosen over time, especially in areas with temperature fluctuations, and they may distort the tubing or hose over time since most of the tension is on one side of the clamp. They also require more time and effort to install, as the worm gear must be rotated numerous times to tighten.
Squeeze-style or spring clamps are made of a single strip of cut spring steel with tabs on both ends. They are pressed together to enlarge the clamp's diameter and then released after placing the clamp over the hose to secure it in place. Spring clamps are easier and quicker to install, and they are also cheaper to produce than worm gear clamps. They are also less likely to loosen due to vibration, material shrinkage, or temperature changes. However, they do not offer the same level of control as worm gear clamps, as they do not have a captive screw to adjust their tightness. Some users have also reported that spring clamps can get weak or break over time.
In terms of which type of clamp is better for fuel lines, opinions vary. Some people prefer worm gear clamps because they provide more control over the tightness of the clamp and are less likely to get weak or break. Others prefer spring clamps because they are more convenient to use, especially on smaller hoses, and they can maintain tension when the hose expands and contracts. Ultimately, the best choice of clamp will depend on the specific application and personal preference.

Snapper clamps for outboard motors
When it comes to outboard motors, snapper clamps are a popular choice for fuel lines. Snapper clamps offer the security of a worm clamp and the convenience of a squeeze clamp. They are thinner than conventional hose clamps, allowing for the option of using two together. Outboard motors have also been known to use specialised curved zip ties for fuel lines, although these are harder to find.
Snapper clamps are available from various retailers, including West Marine and Amazon, as well as marine supply houses. When purchasing snapper clamps, it is important to ensure they are the correct size for your fuel lines. It is also recommended to check clamps after launching an outboard motor, as they may need an extra turn to tighten them properly.
As an alternative to snapper clamps, worm gear clamps are also commonly used for fuel lines. Worm gear clamps are available in various sizes and provide constant tension to secure the fuel line. However, they may loosen over time, especially in areas with fluctuating temperatures, so regular checking and tightening are necessary.
Another option for fuel lines is spring clamps, which are often chosen due to their low cost and ease of installation. Steel pinch clamps are also mentioned as a viable choice for fuel lines. Regardless of the type of clamp chosen, ensuring a secure and leak-free connection is crucial for the safe and efficient operation of outboard motors.

Spring clamps for cheap, quick fixes
Spring clamps, also known as constant-tension clamps, are a popular choice for clamping fuel lines due to their simplicity, ease of installation, and affordability. They are designed to automatically adjust their tension as the hose expands or contracts due to temperature changes, ensuring a continuous and consistent seal. This makes them ideal for automotive cooling systems where temperature fluctuations are common.
Spring clamps use spring steel, which provides consistent pressure on the hose, making them suitable for fuel lines. They are available in various sizes, but it's important to ensure you select the correct size for your specific application. Spring clamps are also limited in terms of adjustability and may not be suitable for very high-pressure applications.
When clamping a fuel line with a spring clamp, it is crucial to ensure that the clamp is properly positioned and tightened evenly. A loose or improperly positioned clamp can lead to fuel leaks, which can be extremely dangerous. Over-tightening the clamp should also be avoided, as it can cause the hose to become pinched or flattened, resulting in potential leaks and hose damage.
Spring clamps are widely available at automotive stores and online retailers, often offering free shipping. They are a cost-effective solution for securing fuel lines and can be easily installed, making them a popular choice for quick fixes. However, it is important to note that spring clamps have limited adjustability, and regular inspection and maintenance of fuel lines and hose clamps are essential to prevent leaks and ensure the safety of your vehicle.

All-metal clamps for durability
When clamping a fuel line, one of the recommended options is to use all-metal clamps. Metal clamps are known for their durability, and they are a better choice than plastic clamps, which are not reusable. Metal clamps are also preferable to stainless steel worm gear clamps, which tend to loosen over time. If you are in an area that gets hot and cools down, you should check stainless steel worm gear clamps at least once.
ABA mini fuel injection-style clamps are perfect for fuel lines and any small-diameter hoses. They feature smooth interiors that will not cut soft hoses, and they are made of 100% stainless steel. They also have a smooth 360-degree seal on hoses and higher corrosion resistance than standard plated fuel injection clamps.
However, it is important to note that metal screw-type hose clamps have a flat spot inside the circle where the screw housing is, which does not allow for a full 360-degree clamping action. This can be an issue with plastic fuel connectors on motors, as they can crack easily. People also tend to overtighten metal screw clamps, which can cut the hose.
To avoid these issues, it is recommended to use light clamping pressure when using metal clamps. If the hose, barb, and clamp are sized correctly, only light pressure is needed to seat the hose onto the barbs and resist expansion if the hose is under tension or pressure.
