It weighs 3.6 oz and measures 2.6\" x 1.6\" x 7\". Compatibility spans two stove families, listed below.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Keep Liquid-Fuel Stoves Running\u003c\/h2\u003e\n\u003cp\u003eLiquid-fuel stoves depend on consistent pump pressure to draw fuel from the bottle and vaporize it at the burner. A worn or failed pump means the stove cannot run, regardless of how much fuel remains. Replacing the pump with a direct Primus spare restores the stove to its original operating condition without requiring a full stove replacement.\u003c\/p\u003e\n\n\u003ch2\u003eBroad Compatibility Across Two Stove Families\u003c\/h2\u003e\n\u003cp\u003eThe ErgoPump covers the MultiFuel family (OmniLite Ti (3219), OmniFuel (3289), MultiFuel, EtaPower MF, and Gravity MF (3281)) as well as the VariFuel family, including the Gravity VF and VariFuel stoves. It also fits hose P732490 and hose P732920 when used with a black connection, making it a single spare that covers a wide range of Primus liquid-fuel hardware already in the field.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete pump assembly:\u003c\/strong\u003e ships as the full pump unit, not individual seals or sub-components\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMultiFuel family compatibility:\u003c\/strong\u003e fits OmniLite Ti (3219), OmniFuel (3289), MultiFuel, EtaPower MF, and Gravity MF (3281)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariFuel family compatibility:\u003c\/strong\u003e fits Gravity VF and VariFuel stoves\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHose compatibility:\u003c\/strong\u003e fits hose P732490 and P732920 with a black connection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimus part number:\u003c\/strong\u003e P732231\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eValue\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003e3.6 oz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions\u003c\/td\u003e\n      \u003ctd\u003e2.6\" x 1.6\" x 7\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePrimus Part Number\u003c\/td\u003e\n      \u003ctd\u003eP732231\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMultiFuel Compatible Models\u003c\/td\u003e\n      \u003ctd\u003eOmniLite Ti (3219), OmniFuel (3289), MultiFuel, EtaPower MF, Gravity MF (3281)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVariFuel Compatible Models\u003c\/td\u003e\n      \u003ctd\u003eGravity VF, VariFuel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCompatible Hoses\u003c\/td\u003e\n      \u003ctd\u003eP732490, P732920 (with black connection)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThis pump is for owners of the Primus stove models listed above who need to replace a worn, damaged, or non-functioning pump to restore liquid-fuel operation.

The MultiFuel family includes the OmniLite Ti (3219), OmniFuel (3289), MultiFuel, EtaPower MF, and Gravity MF (3281). The VariFuel family includes the Gravity VF and VariFuel. It also fits hose P732490 and P732920 when used with a black connection.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eIs this the complete pump or just a seal and repair kit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Primus ErgoPump is the complete pump assembly, not a seal kit or sub-component set. Replacing the full pump unit is the straightforward path to restoring fuel delivery on a multifuel or VariFuel stove when the existing pump has worn out or failed.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes this pump work with both gas canisters and liquid fuel?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ErgoPump is the liquid-fuel component of compatible Primus multifuel stoves, pressurizing the fuel bottle so the stove can draw and vaporize liquid fuel. The compatible stoves can also run on gas canisters, but the pump itself serves the liquid-fuel side of the system.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the Primus part number for this pump?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Primus part number for the ErgoPump replacement is P732231. Use this number when cross-referencing with a stove's service documentation or when confirming compatibility with a specific model year of a listed stove.\u003c\/p\u003e","brand":"Primus","offers":[{"title":"Default Title","offer_id":50867595804742,"sku":"LM-319338","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/319338.jpg?v=1793403291","url":"https:\/\/terrainvault.com\/products\/primus-ergopump-replacement-pump-for-multifuel-and-varifuel-stoves","provider":"TerrainVault","version":"1.0","type":"link"}
