It runs off your van's main diesel fuel tank, draws only 4–27W of electrical power, and operates effectively up to 13,120 ft (4,000 m) with the included altitude sensor. For Sprinter and ProMaster van builds, this is the clean, reliable heating solution that seasoned builders reach for.\u003c\/p\u003e\u003cdiv style=\"background:#fff3cd;border-left:4px solid #ffc107;border-radius:4px;padding:12px 16px;margin-bottom:20px;color:#856404;font-size:0.9rem;\"\u003e\n\u003cstrong\u003e⚙️ Van-Specific Install Notes:\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eMercedes Sprinter:\u003c\/strong\u003e Kit includes a fuel standpipe (not T-piece).
