It replaces common factory testers (Walbro 57-21-1, Zama ZPG-2, Tillotson 243-504, Stens 705-020) and ships with multiple fittings and three fuel hoses for quick compatibility with most carburetor fittings.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the pressure range affect leak detection?\u003c\/h3\u003e\n\n\u003cp\u003eUsing a 0–200 kPa (0–29 psi) range lets you simulate the small positive pressure required to check needle valve sealing and diaphragm integrity without over-pressurizing delicate parts. The gauge gives a visible reading so you can tell if pressure drops — indicating a leak — or remains steady, indicating a sealed needle\/diaphragm.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eRange: 0–200 kPa (0–29 psi) for precise small-engine testing\u003c\/li\u003e\n  \u003cli\u003eClear dial shows pressure changes for quick diagnostics\u003c\/li\u003e\n  \u003cli\u003eSafe for most small carburetor housings when used properly\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich adapters and hoses are included, and why do they matter?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit includes two additional adapters (3 mm and 4 mm fittings) plus three fuel hoses sized ID 3\/32\", ID 3 mm, and ID 6 mm to fit a wide variety of carburetor inlet sizes and fittings.
