Primus Gravity Multifuel Maintenance Kit

The Primus Gravity Multifuel Maintenance Kit is a conversion upgrade for owners of the Primus Gravity 3 gas stove (model 328196) who want to add liquid-fuel capability. The kit enables the stove to run on naphtha and lead-free gasoline, with kerosene as an emergency option, and includes every component needed to make the switch.

Expand Your Fuel Options Without Replacing Your Stove

The Gravity 3 gas stove is a capable platform, but gas canisters are not always available on extended trips, in remote regions, or in cold conditions where canister pressure drops. This kit converts that existing stove to accept liquid fuels, so the stove remains usable when canisters are scarce. Kerosene support adds a further fallback for genuine emergencies where cleaner fuels are unavailable.

A Complete Conversion in One Package

Rather than sourcing individual parts, the kit bundles the Ergopump, a 0.6-liter fuel bottle, jet nipples, a fuel cap, a multi-tool with a cleaning needle, and a storage bag. The cleaning needle and multi-tool address the maintenance reality of liquid-fuel stoves: jets require periodic clearing to maintain consistent output, and having the right tool already in the bag means that task does not require improvising in the field.

Features

• Ergopump: pressurizes the fuel bottle for liquid-fuel operation
• 0.6-liter fuel bottle: included vessel sized for the Gravity 3 system
• Jet nipples: liquid-fuel jets required for multifuel operation
• Fuel cap: seals the fuel bottle during transport and storage
• Multi-tool with cleaning needle: for field maintenance and jet clearing
• Storage bag: keeps all kit components together

Specifications

Who This Is For and Isn't

This kit is for current owners of the Primus Gravity 3 gas stove (model 328196) who want the flexibility to run liquid fuels, particularly useful for travel to areas where isobutane canisters are difficult to source or for expeditions where fuel availability is uncertain.

This kit does not include fuel of any kind. It is compatible only with the Primus Gravity 3 gas stove (model 328196) and requires that stove to already be owned. It is not a standalone stove or a complete cooking system.

Common Questions

Which stove does this kit fit?

The Primus Gravity Multifuel Maintenance Kit is designed specifically for the Primus Gravity 3 gas stove, model 328196. No other Primus stove models are listed as compatible with this kit.

What liquid fuels can the converted stove use?

After conversion with this kit, the Primus Gravity 3 can run on naphtha and lead-free gasoline. Kerosene is listed as a supported fuel for emergency situations. Fuel of any kind is not included with the kit.

Does the kit include a fuel bottle?

Yes. The Primus Gravity Multifuel Maintenance Kit includes a 0.6-liter fuel bottle along with a matching fuel cap, so no separate bottle purchase is required to begin using liquid fuels with the converted stove.

What is the Ergopump used for?

The Ergopump, included in this kit, pressurizes the fuel bottle so that liquid fuel can be fed to the stove burner. Pressurizing the bottle is a required step in liquid-fuel stove operation that is not needed when running on gas canisters.

Why is a cleaning needle included?

Liquid fuels can leave deposits that clog the stove jet over time. The multi-tool with cleaning needle included in the Primus Gravity Multifuel Maintenance Kit allows the jet to be cleared in the field, restoring consistent fuel flow without needing additional tools.
