There are several ways to add a gas gauge to a fuel tank. One way is to replace the gas cap with a gas cap fuel gauge, if you can find one that fits your tank. Another method is to use a wooden dowel or dipstick, marking it at various levels to indicate the amount of fuel in the tank. This is a low-cost option but may not be as precise as other methods. Drilling holes in the tank and connecting a clear fuel hose is another option for a visual representation of the fuel level, but it may not be safe and can devalue the vehicle. Universal sender units with gauges are also available and can be adapted to your tank using the tank depth.

What You'll Learn
Using a dipstick
A dipstick is a graduated measuring device that can be used to determine the exact amount of fuel in a tank. It can be uncalibrated, measuring the inches of fuel, or calibrated to measure the number of gallons.
To use a dipstick to measure fuel, start with an empty tank. Then, add one gallon of fuel, insert the dipstick, and mark the wet line. Repeat this process, adding more fuel in increments and marking the dipstick at each stage until the tank is full. This will allow you to determine how many gallons of fuel are in your tank by inserting the dipstick and reading it.
While dipsticks provide an accurate measurement of fuel, they can be time-consuming to use. The process involves retrieving the dipstick, opening the tank, inserting and removing the dipstick, reading the measurement, cleaning the dipstick, closing the tank, and storing the dipstick. This can be especially inconvenient for boat operators, as they may need to stop the boat and perform the task while bobbing around in neutral.
However, combining the use of a dipstick with gauge readings can be a good compromise. Using a dipstick to verify fuel levels before setting off on a journey can provide accurate information, while occasional gauge readings offer a convenient way to monitor fuel levels during the trip.
To create a simple dipstick, you can use a wooden dowel rod or a dark "oak" dowel from a hardware store. Mark the dowel at specific intervals, such as every gallon or every five gallons, to indicate the fuel level. It is recommended to create a spare dipstick as well, as it can be challenging to get precise measurements.

Drilling holes and inserting a clear fuel hose
To begin, you will need to drill two holes in your fuel tank, one at the top and one near the bottom. The exact placement of these holes will depend on the shape and size of your tank. It is important to note that drilling holes in your fuel tank may be dangerous and could damage your vehicle, so proceed with caution.
Once the holes are drilled, you will need to insert a clear fuel hose through them, connecting the hose on the outside of the tank to both holes. This hose will provide an instant visual representation of how full your tank is, as the fuel level inside the hose will match the fuel level in your tank. You can even use a Sharpie to mark the hose at intervals to indicate quarter or half tanks.
Before drilling, it is important to measure the depth of your tank and ensure it is empty to avoid spills. You should also consider how you will seal the hose gas-tight where it enters the tank, as this is crucial for safety.
While this method is simple and relatively affordable, it may not be the most accurate way to gauge fuel levels, and it may not be suitable for all vehicles or fuel tanks. Other methods for adding a fuel gauge include using a dipstick, installing a low fuel light, or purchasing a universal sender unit with a gauge.

Using a fuel gauge cap
One way to add a gas gauge to a fuel tank is to replace your gas cap with a gas cap fuel gauge. You can find these online, with brands such as JFG Racing, TUSK, Polaris, Motorcraft, and Speedway Motors offering them.
Before purchasing a fuel gauge cap, you should measure how deep your tank is and check whether it is a regular shape. This will allow you to determine whether you need to adapt the gauge to your tank. If your tank is not a regular shape, you will need to calibrate the gauge for accuracy.
Once you have purchased a suitable fuel gauge cap, you can install it onto your fuel tank. This will allow you to easily check your fuel level by simply looking at the cap.
While this method is simple and effective, it is worth noting that some users have reported issues with aftermarket gauges in the past. In some cases, the needle may bounce around on every bump, leading to inaccurate readings. However, with the variety of options available, it is possible to find a suitable and accurate fuel gauge cap for your needs.

Installing a universal sender unit
The first step is to measure the depth of your fuel tank. This measurement is crucial as it determines the size of the universal sender unit you will need. It is recommended to get a unit that is an inch shorter than the height of your tank. Additionally, ensure that the unit has enough clearance, typically requiring an inch of space at the bottom of the tank.
Once you have selected the appropriate universal sender unit, you will need to prepare your fuel tank for installation. Start by draining the existing fuel from the tank and washing it out to remove any residue or debris. After drying the tank, you can proceed to blow out the pickup tube and wipe down the inside of the tank to ensure it is clean and free of any foreign objects.
The next step is to create a mounting hole for the universal sender unit. Using a drill, create a small pilot hole first and then gradually increase the size until it accommodates the mounting hardware. Be cautious to catch any debris that may fall into the tank during the drilling process. You can use a vacuum and air blower to remove any fallen pieces.
Finally, install the universal sender unit according to the manufacturer's instructions. Ensure that the unit is securely mounted and sealed properly to prevent any leaks. Once installed, you can connect the unit to your fuel tank and gauge to start monitoring your fuel levels accurately.

Using a wooden dowel
To create a wooden dowel fuel gauge, start by obtaining a wooden dowel that fits through the neck of your fuel tank. The dowel should be made from a type of wood that does not easily deteriorate when exposed to gasoline, such as oak. Ensure the dowel is longer than the depth of your tank so that you can easily remove it and read the fuel level.
Next, you will need to mark the dowel to indicate the fuel level. Begin by emptying your tank completely and marking the dowel at the bottom of the tank as the "empty" mark. Then, gradually fill the tank with a measured amount of fuel, noting the volume after each addition. Common increments are 5, 6, or 10 gallons. Mark the dowel at each level, using a tool like a Dremel to create notches at the appropriate intervals. You can also use a black Sharpie to highlight the notches and write the corresponding volume ("5," "10," "15," etc.) on the stick.
Once your dowel is marked, you can insert it into the tank to check the fuel level. Remove the dowel and note the highest notch that is still submerged in fuel to determine the approximate volume remaining in the tank.
It is a good idea to create a spare dipstick, as it can be challenging to recreate the exact measurements, and you will need to start with an empty tank to ensure accuracy. Additionally, consider using a synthetic material, such as a fishing bobber, as an alternative to wood, as gasoline can deteriorate some materials over time.
