I chased a lot of issues( maintenance items that needed serviced anyways) but no more cold start issues. Fires right up. Will update in a month or so if it dies on me. But they’re cheap, and only take a few minutes to swap out Review: Nice construction, used for pond water feature rather than fuel so s tad over engineered for the purpose but I like that. Good fit well made. ## Features - Specifications: 3/8 inch (10 mm) OD. Minimum upstream pressure: 0.2 bar (2.9 psi). Working pressure range: 0.2–6 bar (2.9–87 psi).
