Frame-Mounted Pump for Suzuki ATVs

The Quantum HFP-278 is a mechanical fuel pump designed as an OEM replacement for a wide range of Suzuki all-terrain vehicles. It fits models including the ALT125, ALT185, LT230G, LT250EF and LT-F230 produced between 1983 and 1987. The pump also serves King Quad and QuadRunner series from 1987 through 2002. Transparent housing allows quick visual inspection of fuel flow.

Steady Delivery Under Continuous Operation

A mechanical diaphragm driven by the engine cam provides consistent fuel pressure across the full rpm range without the voltage sensitivity of electric units. Flow remains stable during extended trail rides or farm work where the engine runs at constant throttle for long periods. No electrical connections mean there is no wiring harness to corrode or relay to fail in wet conditions.

Bolt-On Fitment With Transparent Body

The frame-mounted design uses the original Suzuki bolt pattern so installation requires only basic hand tools and no bracket fabrication. Transparent polymer construction resists ethanol-blended fuels and lets the rider confirm primer function and filter condition at a glance. Mounting points align with factory locations on LT-F4WD, LT300E and LT-F300F chassis from 1987 to 2002.

Questions about this item

How much heat does the HFP-278 mechanical fuel pump generate during all-day operation on a Suzuki QuadRunner?

As a purely mechanical diaphragm pump driven by the engine cam, the HFP-278 produces no electrical heat and only negligible frictional warmth during continuous use.

Which fuel lines and fittings must I already have to install the HFP-278 on a 1991 Suzuki King Quad LT-F4WD?

You need the original Suzuki inlet and outlet fuel lines with the correct barb diameters and clamps that match the pump’s mounting flange on the LT-F4WD frame.

Will the HFP-278 bolt directly to the frame of my 1985 Suzuki LT230G without modifying the mounting points?

Yes, the HFP-278 is an OEM replacement designed for the LT230G frame mounts, so it aligns with the original bolt pattern and fuel-line routing.
