Weather Guard Fuel Tank with Pump: The Complete Guide to Selecting, Installing, and Maintaining Your Fuel Transfer System

The bottom line: A Weather Guard fuel tank with pump is one of the most reliable and durable solutions for transporting and transferring diesel fuel or hydraulic fluid to job sites. These tanks are built with heavy-duty 12-gauge steel, feature interior baffles for stability, and come with a limited lifetime warranty. However, the pump that draws fuel from the tank and delivers it to your equipment is just as critical as the tank itself. When it comes time to replace or upgrade the fuel pump inside your vehicle's fuel system, choosing a high-performance replacement like a KEMSO fuel pump ensures your engine gets the consistent pressure and flow it needs to run reliably for years.

What Is a Weather Guard Fuel Tank with Pump?

A Weather Guard fuel tank with pump is a complete, ready-to-install system designed for safely transporting fuel to job sites and equipment. The Weather Guard Model 358-3-02 is a 100-gallon rectangular steel transfer tank that comes with a Fill-Rite FR1210H 12V DC pump capable of delivering up to 15 gallons per minute (GPM) of fuel. This tank is specifically designed for non-flammable fluids like diesel fuel and hydraulic fluid only. It is not intended to be connected as an auxiliary tank to your vehicle's primary fuel system.

The tank features a Brite White ARMOR TUF® powder coat finish for long-term durability, interior baffles that minimize fluid motion during transport (which extends the tank's life), and a vented, lockable filler cap to prevent pressure buildup. It also includes rubber isolation bushings that absorb road vibration, protecting the tank from damage during transit.

Important Installation and Safety Guidelines

Before you install a Weather Guard fuel tank with pump, you must follow these critical guidelines. Failure to do so will void your warranty:

1. Do not swap the fill cap and pump locations. The tank is designed with specific mounting points, and altering them compromises structural integrity.

2. Do not install risers between the fuel tank fitting and the pump. This creates a leverage point that can crack the tank or damage the pump mount.

3. Do not use extension pipes to raise the height of the transfer pump. The pump is designed to sit at a specific height relative to the tank.

4. Do not install a pump weighing over 30 pounds on a standard-duty tank. The 30-pound limit includes the pump and any accessories such as filter kits or meters. For heavier pumps, a Severe Series tank is required.

5. Only use the tank for non-flammable fluids. Weather Guard transfer tanks are approved for diesel fuel and hydraulic fluid only. They are not designed for gasoline or other flammable liquids.

How to Properly Install Your Weather Guard Fuel Tank with Pump

Installing a Weather Guard fuel tank with pump is a straightforward project for anyone with basic mechanical skills. Plan for about 2 to 3 hours for the installation.

What you will need:

  • Weather Guard fuel tank with pump kit
  • Mounting hardware (typically bolts and washers for your truck bed)
  • Wrench set
  • Drill with metal drill bits (if mounting holes are needed)
  • Safety glasses and gloves

Installation procedure:

Step 1: Position the tank in your truck bed. Place the tank in the desired location, ensuring it sits flat and level. The tank should be centered and secure against the front or side of the bed.

Step 2: Secure the tank to the truck bed. Use the rubber isolation bushings included in the kit to mount the tank. These bushings absorb road vibration and protect both the tank and your truck bed. Drill mounting holes if necessary, and bolt the tank firmly in place.

Step 3: Install the pump. The Fill-Rite FR1210H pump mounts directly to the 2-inch NPT bung on the top of the tank. Do not use any risers or extension pipes. Tighten the pump securely by hand, then use a wrench to snug it. Do not overtighten.

Step 4: Attach the suction pipe. Insert the telescoping suction pipe into the pump inlet. The pipe should extend down into the tank so it reaches near the bottom but does not touch the tank floor. Adjust the length and secure it.

Step 5: Connect the dispensing hose and nozzle. Attach the 12-foot static wire hose to the pump outlet. Connect the manual nozzle to the other end of the hose.

Step 6: Connect the battery cables. Run the 18-foot power cord from the pump to your vehicle's battery. Connect the positive (red) cable to the positive terminal and the negative (black) cable to the negative terminal. Ensure the connections are clean and tight.

Step 7: Test the system. Fill the tank with diesel fuel. Turn the pump on and check for leaks at all connections. Dispense a small amount of fuel to confirm the pump is working properly and the nozzle functions correctly.

Common Mistakes to Avoid When Installing a Fuel Transfer Tank

Even experienced DIYers make errors during installation. Avoid these common pitfalls:

Not checking the pump duty cycle. The Fill-Rite FR1210H pump has a duty cycle of 30 minutes on and 30 minutes off. Running the pump continuously beyond this limit can overheat and damage the motor. Always let the pump cool down between uses.

Using the wrong type of fuel. Weather Guard transfer tanks are designed for diesel and hydraulic fluid only. Using gasoline or other flammable liquids creates a serious fire hazard and voids the warranty.

Mounting the tank without vibration isolation. Always use the rubber isolation bushings provided. Without them, road vibration can cause metal fatigue, leading to cracks in the tank or mounting brackets.

Forgetting to ground the system. The static wire in the hose is there for a reason. It prevents static electricity buildup during fuel transfer. Always ensure the hose is properly connected and the system is grounded to the vehicle's chassis.

How to Maintain Your Weather Guard Fuel Tank and Pump

Proper maintenance extends the life of your fuel transfer system significantly. Follow these simple practices:

1. Drain the tank regularly. Water and sediment accumulate in the bottom of the tank over time. Use the 3/8-inch drain port to drain the tank every few months, or more often if you refuel frequently.

2. Replace the filter. The Fill-Rite pump includes a strainer that should be cleaned or replaced periodically. A clogged filter reduces flow rate and forces the pump to work harder.

3. Inspect hoses and connections. Check the dispensing hose for cracks, kinks, or wear. Replace the hose immediately if you see any damage. A leaking hose is a safety hazard and wastes fuel.

4. Keep the tank clean. When not in use, keep the filler cap locked and sealed. Dirt and debris that enter the tank can contaminate the fuel and damage the pump.

5. Lubricate the pump. The Fill-Rite FR1210H pump has sealed bearings that do not require regular lubrication. However, if the pump sits unused for long periods, run it for a few minutes every month to keep the seals and motor in good condition.

Why Your Vehicle's Internal Fuel Pump Matters Too

While a Weather Guard fuel tank with pump is essential for transferring fuel to your equipment, the fuel pump inside your vehicle's fuel tank is what keeps your engine running. Whether you drive a daily commuter, a work truck, or a performance vehicle, the internal fuel pump wears out over time. A failing fuel pump causes hard starts, sputtering during acceleration, a whining noise from the rear of the vehicle, and eventually, a complete breakdown.

When it is time to replace your vehicle's internal fuel pump, you want a product that delivers reliable performance and lasting durability. This is where KEMSO fuel pumps come in.
