The Fill-Rite FR4204H is the highest-flow option here, rated at 20 gallons per minute, while the FR1204H offers 15 GPM in a similar pump-only design. The TaskStar is a 13 GPM choice for diesel and other listed fluids; TRUPOW suits buyers who need reversible pumping at a lower flow rate. The Steauty kit includes hoses and accessories, but its stated 120 gallons per hour equals about 2 GPM.
| Product | Stated Flow | Best For |
|---|---|---|
| Fill-Rite FR4204H | 20 GPM | Highest listed flow |
| Fill-Rite FR1204H | 15 GPM | Durable 12V pump-only setup |
| TaskStar | 13 GPM | Diesel transfer with listed lift details |
| TRUPOW | Up to 3.7 GPM | Reversible pumping |
| Steauty | 120 GPH, about 2 GPM | Portable kit with included accessories |
Fill-Rite FR4204H 20 GPM Pump

The FR4204H has the highest stated flow rate among these choices: up to 20 gallons per minute. Its cast-iron construction is intended for rough operating environments, and thermal overload protection is designed to help prevent motor overheating during abnormal use. The removable junction box rotates 180 degrees to make wiring and installation easier in tight spaces.
Best for: Buyers prioritizing the highest listed transfer rate and a robust pump body. The listing names gasoline, diesel, kerosene, ethanol blends, methanol blends, and biodiesel as compatible fluids. Limitation: This is a pump-only model, so confirm what additional equipment your installation requires before buying.
Fill-Rite FR1204H 15 GPM Pump

The FR1204H delivers a stated 15 GPM and shares several practical features with the higher-flow Fill-Rite model. It has a cast-iron body, thermal overload protection, and a removable junction box that rotates 180 degrees. Its product name lists gasoline, diesel, kerosene, ethanol blends, methanol blends, and biodiesel.
Best for: Buyers who want a substantial stated flow rate but do not need the 20 GPM rating of the FR4204H. It was selected for its listed fluid range and durable construction. Limitation: It is a pump-only model, and its stated flow is lower than the FR4204H’s.
TaskStar 13 GPM Diesel Transfer Kit

TaskStar states a flow rate of up to 13 GPM and identifies diesel, kerosene, machine oil, and transformer oil as compatible fluids. Its listing gives a maximum suction distance of 9.8 feet and a pumping height of 26.2 feet. The pump uses a 160-watt copper motor, according to the product information.
Best for: Buyers transferring listed fluids where the stated suction distance and pumping height matter, including agricultural or equipment-refueling contexts. It offers a middle ground between the two Fill-Rite flow ratings and the lower-flow options. Limitation: The supplied compatibility information does not list gasoline, so choose another option if gasoline transfer is required.
TRUPOW 12V Reversible Transfer Pump

TRUPOW is a self-priming 12V pump rated for up to 3.7 GPM. Its switch enables reversible pumping without moving the pump, and the listing states a maximum suction length of 4.9 feet and lift of up to 19 feet. Listed fluid limits include gasoline blends up to E15, diesel blends up to B20, and kerosene. Product information also describes thermal protection and a built-in bypass.
Best for: Buyers who value the ability to reverse the pumping direction and need a compact, lower-flow option for the listed fuels. Limitation: Its maximum stated flow is much lower than the Fill-Rite and TaskStar pumps, so it is not the strongest choice for the fastest transfers.
Steauty 12V Fuel Transfer Pump Set

The Steauty set is described as a 12V pump with an 80-watt pure copper motor and a maximum delivery rate of 120 gallons per hour. That converts to about 2 gallons per minute, notably below the other products’ stated GPM ratings. The listing says hoses and accessories are included, requires no assembly, and comes with a portable case, non-slip handles, and a pressure release valve.
Best for: Buyers who prefer a portable set with transfer accessories included. Limitation: Its stated flow is comparatively low, so it is not the best match when high-volume transfer speed is the priority.
Buying Guide: How To Choose A High-Volume Fuel Transfer Pump
Which flow rate should you compare?
Compare stated gallons per minute (GPM) when speed is your priority. In this group, the FR4204H leads at 20 GPM, followed by the FR1204H at 15 GPM and TaskStar at 13 GPM. TRUPOW lists up to 3.7 GPM. Steauty’s 120 GPH is approximately 2 GPM, so check units carefully rather than comparing the number 120 directly with GPM ratings.
Does the pump work with your fuel?
Check the product’s stated fluid compatibility before purchase. The Fill-Rite product names list several fuel types and blends; TRUPOW specifies gasoline up to E15, diesel up to B20, and kerosene; TaskStar lists diesel, kerosene, machine oil, and transformer oil. Do not assume compatibility with an unlisted fluid.
Do you need a pump-only model or a kit?
The two Fill-Rite models are explicitly pump-only, so check whether your setup needs separately sourced hoses or other parts. Steauty says hoses and accessories are included. Review the complete product listing to confirm exactly what is supplied and whether it suits your intended installation.
Will the pump reach your tank?
For a setup with height or distance constraints, compare the stated suction and lift figures. TRUPOW lists 4.9 feet of suction and up to 19 feet of lift; TaskStar lists up to 9.8 feet of suction and 26.2 feet of pumping height. These figures are product claims, not a guarantee of the flow rate in every installation.
