Drilling a hole without causing an explosion
Drilling a hole in a plastic fuel tank for a pickup can be a dangerous task due to the risk of explosion. Here are some detailed instructions to help you drill a hole without causing an explosion:
First, it is crucial to understand the risks involved. An empty gas tank can be extremely dangerous, as it essentially becomes a Fuel Air Explosive ready to detonate. Even a small amount of residual fuel or fumes can be ignited by sparks from the drill, leading to a potentially deadly explosion. Therefore, your primary goal is to ensure the tank is entirely free of fuel and fumes before drilling.
Start by draining the fuel tank completely. Once drained, rinse the tank with water and a neutralizing agent, such as dish soap, to eliminate any remaining fuel vapors. Turn the tank upside down and leave it for several hours to ensure all vapors evaporate. You can also use compressed air to blow out the tank and speed up the drying process, but be cautious not to pressurize the tank, as this could rupture it.
After confirming that the tank is entirely free of fuel and vapors, you can begin the drilling process. It is recommended to use a hand-operated drill instead of a power drill, as power tools can emit sparks that could ignite fumes. Work in a well-ventilated area outdoors, ensuring plenty of airflow.
Additionally, consider using a plastic welder to repair the hole instead of drilling a new one. Plastic welding is a safer method that does not involve flames or high temperatures. You can use a combination of a heat gun, a soldering gun with a flat round tip, and strips of high-density poly ethylene (such as milk jug plastic) to weld the hole shut.
If you decide to proceed with drilling, take extra precautions. Wear protective gear, including eye protection and gloves, and ensure you are using the correct drill bit for plastic. Go slowly and apply gentle pressure to avoid damaging the tank or creating excessive friction, which could generate sparks.
Remember, safety should always come first when working with fuel tanks. Take your time, follow these instructions carefully, and do not skip any steps to minimize the risk of explosion or injury.

Using a plastic welding kit
Plastic welding is a common method for repairing holes in plastic fuel tanks. It is a relatively simple task that can be done at home or by professionals at body shops. Here is a step-by-step guide on using a plastic welding kit to repair a hole in a plastic fuel tank for a pickup:
Prepare the Workspace and Materials:
First, ensure you are working in a well-ventilated area to manage dust and fumes. Wear protective gear, including a long-sleeved shirt, heat-resistant gloves, a dust mask, and polycarbonate glasses.
Next, gather the necessary materials. Plastic welding kits typically include a welder, varying welder rods, welding tips, and a guide. Ensure you have the appropriate welding rod for the type of plastic you are working with. If you are unsure, use a welding rod testing kit to determine the right rod.
Clean and Prepare the Plastic:
If the plastic has paint on it, remove it with 80-grit sandpaper or an abrasive disc/sanding wheel attached to a drill. Be careful not to scratch the bare plastic underneath.
Create the Joint:
Place the plastic pieces together on a workbench, pushing them as close together as possible to minimize gaps or air pockets. Clamp and tape the pieces together to hold them in place. If you are repairing a hole, ensure the area around the hole is clean and free of debris.
Preheat the Welding Gun:
Allow the welding gun to heat up to the appropriate temperature for the type of plastic you are working with, typically between 390°F to 570°F (200°C to 300°C).
Welding Process:
Once the gun is heated, apply heat to the joint or hole, gradually melting the plastic. Use a speed nozzle with an opening to hold the welding rod as you melt it onto the joint. Move the gun in little circles, scraping and mixing the parent material together.
For additional security, you can tack weld spots every 1 foot (0.30 m) along the joint. Ensure the weld is smooth and strong, and fill any gaps with the welding rod.
Cooling and Finishing:
Allow the weld to cool and solidify. Finish by smoothing out the weld to create a strong and seamless repair.
Plastic welding is an effective method for repairing holes in plastic fuel tanks, and with the right tools and precautions, you can achieve a durable and long-lasting result.
