GPI M-150 Series Fuel Transfer Pump 15 GPM - Reliable Mobile Refueling

In this review of the GPI M-150S 15 GPM Fuel Transfer Pump, the bottom line is straightforward: this kit is aimed at users who need a dependable, portable fuel transfer solution with minimal maintenance and easy installation. The pump's rotary gear design and diecast aluminum housing make it durable without adding unnecessary weight, while the included automatic nozzle, filter kit and factory-installed power cord mean the unit is ready to install and use on a truck or trailer for field or service work.

Key Features

• 15 GPM flow: Delivers fast transfer rates up to 15 gallons per minute for quicker refueling of equipment and vehicles.
• Automatic nozzle: The included automatic unleaded nozzle provides hands-free shutoff to reduce spills and overfills during dispensing.
• Integrated filter: A 10 micron particulate filter with adapter removes debris that could damage engines or fuel systems.
• 12V mobile power: Designed to run from a 12V DC battery, the pump is suited for truck or trailer mounting and field use.
• Durable construction: Rotary gear mechanism with fewer moving parts and a diecast aluminum housing reduces wear and keeps weight down.
• Installation kit included: Comes with telescoping suction pipe, tank adapter, hose, fuse assembly and power cord for a safer, more complete setup.

Who It's For

The M-150S is best for contractors, farmers, motorsport teams and fleet operators who need a portable, higher-flow pump to refill mowers, tractors, race support vehicles or small fleets on site. Its 15 GPM output and automatic nozzle save time when servicing multiple machines and the mobile 12V design suits work from truck or trailer tanks.

Those who need a low-flow precision dispenser, an integrated electronic meter, or a permanently installed on-site fueling station should consider other options; the M-150S is optimized for mobile transfer, speed and durability rather than metering precision.

Pros & Cons

Pros

• High flow rate reduces refill time for multiple machines.
• Easy installation with factory power cord and spin collar makes setup straightforward.
• Included 10 micron filter and durable rotary gear pump equate to lower maintenance and protection for downstream equipment.
• Lockable nozzle holder and diecast housing add theft deterrence and reduced bung stress.

Cons

• Capacity impressions vary among users, so those needing exact tank run estimates may want to verify fit for their tanks.
• No integrated electronic meter in this kit, so separate metering is required if precise volume tracking is needed.

Specifications
