Delphi EX631756 fuel injector for the 2006-2009 Gillig Low Floor 6-cylinder 10.8L and other vehicles sprays diesel fuel into the engine in a controlled pattern. Like other Delphi injectors, it is tested using OE methodologies.
- 100% O-ring replacement
- No internal seal rings, which minimizes leakage
- Recessed fuel exit to minimize possible plugging
- Reduced spray variation and an accurate fuel spray pattern, which help emissions and cold start capabilities
- Thermal isolation of the fuel from the engine by drawing manifold heat away from the fuel rail, which addresses hesitation from vapor lock
Quick facts

Hard cold starts, rough running or fuel leaking at the injector body can mean an injector has gone bad. Before you replace one, rule out the fuel supply, filters and wiring, since a different fault can look the same. This engine takes one injector per cylinder, six in all, and this listing is one injector.
