Diagnose your GM Duramax like a pro with this Yoursme fuel pressure test kit! Specifically designed for 6.6L Duramax diesel engines, this kit lets you test both fuel pressure and vacuum in one handy tool. The 3.5 inch gauge reads from 30 inHg to 15 PSI, giving you accurate readings for those low-pressure fuel systems. The 6-foot reinforced rubber hose with quick coupler makes connecting easy, and there's even a hook for hands-free use while you're working. All the brass components are premium quality - they're sturdy, non-rusting, and built to last. The hose can handle torsion, temperature changes, and pressure without failing. Yoursme stands behind their products with a 30-day money-back guarantee and 12-month warranty, so you can buy with confidence. Whether you're a professional mechanic or a serious DIYer working on GM diesel trucks, this test kit takes the guesswork out of fuel system diagnostics.
