Inspection After Installation

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD and 2019 Nissan NV2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

Check for Fuel Leakage

Turn ignition switch "ON" (with the engine stopped). With fuel pressure applied to fuel piping, check that there is no fuel leaks at connection points.
NOTE: Use mirrors for checking at points out of clear sight.
Start the engine. With engine speed increased, check again that there is no fuel leaks at connection points.
CAUTION: Do not touch the engine immediately after it is stopped because the engine is extremely hot.
