Primus Spider Multifuel Kit for Spider and Express Spider Stoves

The Primus Spider Multifuel Kit is a conversion kit that upgrades a Primus Spider Stove or Express Spider Stove (purchased from 2013 onward) to run on liquid fuels, including naphtha, lead-free petrol, and kerosene for emergency use. The kit includes every component needed for the conversion and stores together in an included bag.

Fuel Flexibility Where It Counts

Gas canisters are not always available in remote locations, at developing-country fuel stops, or on extended expeditions where working with whatever liquid fuel is on hand becomes a necessity. The Primus Spider Multifuel Kit makes that possible by converting a canister-fed Spider stove into a liquid-fuel stove without replacing the stove itself. Naphtha and lead-free petrol are the primary fuels; kerosene is supported as a fallback when nothing else is available.

A Complete Conversion in One Package

The kit ships with a 0.35-liter fuel bottle, an ErgoPump for pressurizing that bottle, and a multi-tool that includes a cleaning needle and jet nipples for field maintenance. The practical storage bag keeps all components together between uses, so nothing gets separated in a gear bin or pack.
