2.5.6. Procedure of check of leak of fuel
After performance of any works on service of fuel system, be convinced of lack of leak of fuel as follows.
Include on 3 about ignition (for turning on of the fuel pump), and then switch off it.
Repeat inclusion/switching off of ignition 3 or 4 times for rise in pressure of fuel in fuel-supply lines (so far pressure of fuel will not be felt as a hand on a fuel return hose).
Under these conditions be convinced of lack of leak of fuel in any part of fuel system.
Check of fuel-supply lines on the car
Because the giving fuel-supply line is under high pressure, observe extra care when working on maintenance.
Visually check fuel-supply lines for existence of leak of fuel, cracks and damages of hoses. Make sure that all collars are reliably fixed. Replace details if necessary.
