Fuel Pump Harbor Freight: The Complete Guide to Choosing the Right Transfer Pump for Your Needs

The bottom line: Harbor Freight offers several fuel pump options that range from $8 to $100, but not all are created equal. While the budget-friendly battery-operated pump (model 63847) works for occasional light use, many users report reliability issues. For serious or frequent fuel transfer needs, you should consider investing in a more durable solution.

What You Need to Know About Harbor Freight Fuel Pumps

If you're searching for a fuel pump at Harbor Freight, you're likely looking for an affordable way to transfer gasoline, diesel, or oil from one container to another. Whether you need to refuel lawn equipment, move fuel from portable containers into your boat's tank, or transfer diesel for your tractor, Harbor Freight has several options worth considering.

The most popular Harbor Freight fuel pump is the 63847 Battery-Operated Liquid Transfer Pump, which runs on two D-cell batteries and costs around $10-$15. This pump is designed for transferring gasoline, water, oil, and other non-corrosive liquids at a flow rate of approximately 6 quarts per minute. It comes with a 24-inch delivery hose and a 13-inch suction hose, making it compact enough for portable use.

However, before you rush to buy one, let me share what real users have experienced.

The Real Story: Harbor Freight Fuel Pump Reliability

I've researched dozens of user reviews and forum discussions about Harbor Freight fuel pumps, and the feedback is mixed at best. Many users report that the battery-operated pump works great initially but fails after a few months of use.

One tractor owner shared on a forum that they went through four of these pumps in five years of tractor ownership. Another user reported having six or eight pumps fail over a four-year period, noting that they never even had to change the batteries before the pumps stopped working.

Perhaps most concerning is a review from a user who posted a six-month follow-up video showing that the pump started filling the battery compartment with gasoline and began leaking. This is a serious safety concern, especially when dealing with flammable liquids like gasoline.

The key issues reported by users include:

  1. Short lifespan: Many pumps fail within a few months to a year of light use
  2. Leaking problems: Gasoline can seep into the battery compartment
  3. Inconsistent performance: Some pumps work well initially but fail without warning
  4. Battery drain: Even with fresh batteries, the pump may stop working

Despite these concerns, some users have positive experiences. One boating enthusiast mentioned using the Harbor Freight D-cell pump to transfer fuel from 5-gallon cans to their boat, calling it "very portable and works great". Another user reported using the same pump to transfer gasoline from multiple cans after repairing their fuel tank, saying it worked perfectly.

Harbor Freight Fuel Pump Options Compared

1. Pittsburgh Multi-Use Transfer Pump (SKU 63144) - $7.99

This is Harbor Freight's highest-rated fuel transfer pump, with over 7,300 customer reviews averaging 4.3 out of 5 stars. It's a manual pump, meaning you have to pump it by hand, but it offers a maximum flow rate of 2.64 gallons per minute. At just one pound, it's highly portable and comes with a 51-inch hose. An added bonus is that it doubles as an air pump for inflating bike tires and sports equipment.

However, one SlashGear writer who tested it was less than impressed, so it's worth reading user reviews carefully before purchasing.

2. Pittsburgh 12V Diesel Transfer Pump

For those who want a motorized option, this pump has an average customer score of 4.5 out of 5 with over 500 reviews. It's built for diesel and kerosene only, not gasoline. The pump features a die-cast aluminum body and heavy-duty cast-iron ¾-inch inlet and outlet ports. Users praise its quality, durability, and compact size.

3. Battery-Operated Liquid Transfer Pump (Model 63847)

This is the most commonly discussed Harbor Freight fuel pump. It uses two D-cell batteries and costs around $10-$15. While it's affordable and convenient for occasional use, the reliability concerns mentioned above are worth considering.

Safety Considerations for Fuel Transfer

When using any fuel transfer pump, safety should be your top priority. Gasoline and other flammable liquids pose serious risks if not handled properly.

Essential safety guidelines from the Harbor Freight manual include:

  • Never use corrosive liquids with the pump
  • Do not use with drinking water
  • Be aware of explosion hazards when pumping gasoline and flammable liquids
  • Only use in well-ventilated areas to avoid flammable vapor buildup
  • Wear ANSI-approved safety goggles and heavy-duty, chemical-resistant work gloves
  • Check all connections for tightness before use to eliminate leaks
  • Remove batteries when not in use
  • Do not mix old and new batteries, or different types of batteries

One forum user raised a sobering point about safety: "I would think long and hard about getting a cheap pump for gas transfer. That boat going up in flames offshore because you bought a Harbor Freight made in China piece of crap while you and your crew have 50 percent burns... won't be comforting". While this may sound dramatic, it underscores the importance of choosing a reliable, properly-rated pump for fuel transfer.

Alternative Options to Harbor Freight Fuel Pumps

If you've read the user reviews and feel uncertain about Harbor Freight's battery-operated pump, you have several alternatives:

Manual Siphon Hoses

Many users recommend shake siphon hoses as a simple, reliable alternative. One forum member described how well they work: "Just put the end with the siphon valve in the gas can, the other end in the tank and give it a shake. That's it. Works amazing for any can". These cost around $10-$15 and have no moving parts to fail.

Fill-Rite Hand Pumps

For a more durable manual option, Fill-Rite hand-operated fuel transfer pumps are designed for low-volume transfer of gasoline, diesel, and oils. These are more expensive than Harbor Freight options but built to last much longer.

12V Electric Pumps

Amazon offers 12-volt fuel transfer pumps that are "100% safe" according to users, with completely sealed designs that prevent sparks. These are suitable for transferring fuel from portable containers to boat tanks or other equipment.

Best Practices for Using a Fuel Transfer Pump

Based on user experiences and expert advice, here are tips to get the most out of your fuel pump:

1. Choose the right pump for your fuel type
Not all pumps work with all fuels. The Harbor Freight 63847 pump is rated for gasoline, water, oil, and other non-corrosive liquids. However, the Pittsburgh 12V pump is specifically for diesel and kerosene only. Using the wrong pump can be dangerous.

2. Inspect the pump before each use
Check for loose or damaged parts. If you notice any leaks or cracks, do not use the pump.

3. Store batteries properly
Remove batteries when the pump is not in use. Never mix old and new batteries or different battery types.

4. Keep the pump clean and dry
After use, allow the pump to drain completely before storing. Do not store the pump upside down.

5. Consider your usage frequency
If you only need to transfer fuel occasionally (a few times a year), the Harbor Freight battery-operated pump may be sufficient. For regular use, invest in a more durable option.
