Description

Fluids Do Not Cooperate. They Must Be Commanded.

Every mechanic has performed the ritual: a mouthful of gasoline from a siphon hose, diesel-soaked gloves from a hand pump that leaked at the seal, an oil pan that overflows because gravity feeds faster than the drain plug can be rethreaded. The Fluid Marshal ends this indignity. Its 12V/24V DC impeller pump transfers fuel, diesel, engine oil, and hydraulic fluid at a governed 1-4 liters per minute — fast enough to drain a motorcycle tank in 90 seconds, slow enough that you never lose control of the stream.

The pump head is a self-priming rotary vane design with a PTFE-impregnated impeller — chemically inert to gasoline, diesel, ethanol blends, and most hydraulic fluids. The automatic shutoff sensor in the intake wand detects air (empty tank) and cuts power within 2 seconds, preventing dry-run damage that kills lesser pumps on their first job. The alligator-clamp power leads connect directly to any 12V car battery or 24V truck/marine battery without a separate power supply. A 6.5-foot delivery hose with a swivel spout clips to the side of any drain pan or jerry can. At 1.8 pounds, it lives in the bottom drawer of your tool chest — not on a shelf in the garage because it is too awkward to retrieve.

You have earned the right to keep fuel out of your mouth.

Key Features

Self-Priming Rotary Vane Pump: PTFE impeller rated for gasoline, diesel, kerosene, engine oil, hydraulic fluid, and ethanol blends up to E85 — no chemical degradation after extended fuel contact

Auto-Shutoff Dry-Run Protection: Air-detection sensor in the intake wand stops the motor within 2 seconds of an empty tank — prevents impeller burnout from running dry

Dual Voltage 12V/24V: Works with passenger vehicle batteries (12V), heavy truck batteries (24V), and marine deep-cycle systems — auto-detects input voltage

1-4 L/min Governed Flow: Variable speed impeller adjusts to fluid viscosity — thinner fluids (gasoline) flow faster; thicker fluids (cold engine oil) flow slower but never stall

6.5ft Delivery Hose: Reinforced PVC with swivel spout clip — reaches from engine bay to drain pan without repositioning the pump

Compact 1.8 lb Body: Fits in a tool chest drawer alongside wrenches and sockets — grab it, clamp it, drain it, stow it

Inline Mesh Filter: 80-micron stainless screen in the intake wand catches particulate before it reaches the impeller chamber

Application Scenarios

The Fluid Marshal earns its keep in the garage, at the dock, and on the farm. Auto mechanics use it to drain fuel tanks before dropping them for pump replacement — clamp to the battery, insert the wand, and walk away while 15 gallons of gasoline transfer into a jerry can in under 10 minutes. Boat owners use the 24V mode on marine batteries to empty fuel/water separators and transfer diesel between saddle tanks. Small-engine technicians drain stale fuel from lawn mowers, generators, and snowblowers without tipping heavy equipment. Farmers transfer diesel from bulk storage to tractor tanks without a hand-cranked rotary pump that seizes every winter. The inline mesh filter catches rust flakes and sediment that would otherwise clog a carburetor — a detail that saves you from diagnosing a "bad fuel" problem that was actually a dirty transfer.

Frequently Asked Questions

Q: Will gasoline damage the pump over time?

A: No. The impeller is PTFE (polytetrafluoroethylene) — the same material used in fuel system seals and gaskets throughout the automotive industry. It is chemically inert to gasoline, ethanol, diesel, and most solvents. The pump housing is glass-filled nylon rated for continuous fuel contact. Flush with a cup of fresh fuel after use to clear the lines.

Q: How fast will it drain a motorcycle gas tank?

A: A typical 4-gallon (15L) motorcycle tank drains in approximately 4-5 minutes at the governed gasoline flow rate. The auto-shutoff sensor stops the pump when the tank is empty, so you don't need to monitor it continuously.

Q: Can it pump thick, cold engine oil?

A: Yes, but flow rate decreases with viscosity. Warm engine oil (180°F+) flows at ~3 L/min. Cold 15W-40 at 40°F flows closer to 1 L/min — still functional, just slower. For cold-weather oil changes, run the engine for 5 minutes first to warm the oil and improve flow.

Q: Does it work with 24V heavy truck batteries?

A: Yes. The pump auto-detects input voltage and adjusts motor speed accordingly. At 24V it draws approximately 3A — well within the capability of any truck battery. The 24V mode is particularly useful for marine applications and commercial fleet maintenance.

Q: What if I accidentally run it dry?

A: The air-detection sensor in the intake wand cuts power within 2 seconds of air ingestion. The pump will not restart until the wand is re-submerged in fluid. This prevents the PTFE impeller from spinning dry against the housing, which is the #1 failure mode of transfer pumps. If the sensor triggers, simply reinsert the wand and cycle power off/on.

PTFE impeller gives me confidence with ethanol fuels

I specifically bought this pump because the impeller is PTFE, not rubber — E10 and E15 gasoline will dissolve rubber pump seals in under a year. I've been running this pump for 4 months transferring E10 fuel between storage tanks, and there's no sign of seal degradation. The auto-shutoff has saved me from dry-running at least a dozen times when I got distracted. Works equally well on my 12V car battery and my tractor's 24V system without any voltage switch. Solid engineering.

Great for winterizing equipment, flow rate is honest

I winterize 6 pieces of equipment every fall — mower, snowblower, generator, pressure washer, ATV, rototiller. This pump makes draining fuel tanks a 30-second job per machine instead of a 5-minute wrestling match with a hand pump. The flow rate for gasoline is realistically about 3 L/min, which is fast enough. Used it on warm diesel too and it handled it fine. My only nitpick: the power cord could be 2 feet longer for reaching batteries in awkward engine bays.

No more mouthfuls of gasoline — worth it for that alone

Been siphoning fuel the old-fashioned way for 20 years and finally bought an electric pump. Should have done this a decade ago. Drained a 16-gallon boat tank in about 5 minutes into jerry cans — the auto-shutoff caught the empty tank instantly. The alligator clamps connect securely to the battery terminals. The inline filter caught some rust flakes that would have ended up in the jerry can if I'd been using a hose siphon. Compact enough to keep in the boat's tool locker.
