Fill-Rite FR1204H 12V 15 GPM Fuel Transfer Pump — Pump-Only, Cast‑Iron Rotary Vane with Thermal Protection

The Fill‑Rite FR1204H is a 12‑volt, 15 GPM cast‑iron fuel transfer pump designed for reliable, high‑flow transfer of gasoline, diesel, kerosene and approved fuel blends.

The FR1204H is a "pump only" model built for heavy use on trucks, trailers and portable tank systems. It ships with a 3/4" street elbow, ground wire, two wire nuts and PTFE tape so installers have the basic fittings they need while retaining flexibility to choose hoses, meters and nozzles to match their setup. Constructed with rotary vane technology and thermal overload protection, this unit delivers steady flow rates while resisting wear in demanding mobile applications.

How does the FR1204H perform for continuous transfer jobs?

This pump maintains a consistent 15 GPM flow using rotary vane technology that tolerates component wear better than some other designs. Thermal overload protection helps prevent motor damage during abnormal loads, giving you longer runtime confidence.

• Rated flow: 15 gallons per minute for fast refueling or bulk transfer
• Rotary vane mechanism preserves flow consistency as parts age
• Thermal overload protection reduces risk of motor overheating
• Designed to pull from tank depths to 8 ft and discharge up to 37 ft

What fuels and environments is this pump compatible with?

The FR1204H is compatible with gasoline, diesel, kerosene, ethanol blends up to 15%, methanol blends up to 15% and biodiesel up to B20. Its cast iron housing and heavy construction make it suited to rough operating conditions found in transport and construction settings.

• Accepted fuels: gasoline, diesel, kerosene, E15, M15, biodiesel up to B20
• Cast iron body resists impact and field wear
• Mobile‑ready for trucks, trailers and portable tanks
• Includes basic installation items: 3/4" street elbow, ground wire, wire nuts, PTFE tape

How easy is installation and maintenance for a field service team?

Installation is straightforward: the junction box is removable and rotates 180° so electrical connections can be made in tight spaces. Routine maintenance is simplified by proven rotary vane internals and the availability of replaceable components, which keeps downtime minimal.

• Rotating junction box eases wiring in cramped locations
• Mounts as a 12V bung‑mounted pump for quick deployment
• Field‑replaceable parts reduce repair time and expense
• Limit lifetime warranty on the 1200 series adds owner protection

What power and mounting considerations should I plan for?

The FR1204H is a 12‑volt pump intended for battery‑powered, bung‑mounted installations on vehicles and portable tanks. It will perform reliably when wired correctly and installed at the recommended tank depth and discharge height.

• Power: 12 V DC for common vehicle battery systems
• Bung‑mount design for secure tank installation
• Capable of suction from 8 ft and discharge to 37 ft heights
• Use appropriate wiring gauge and fusing per installation guide

Who is this for? The Fill‑Rite FR1204H is targeted at fleet managers, contractors, agricultural operators and mobile fuel providers who need a rugged, high‑flow 12V pump that handles common gasoline and diesel blends. It’s ideal when you want a durable cast‑iron unit with proven rotary vane performance, thermal protection and simple, field‑friendly installation—without extra accessories bundled in so you can tailor fittings to your system.
