Vacuum hoses
Replacement of vacuum hoses requires approximately 5 metres of hose (EGR Valve,
EGR Vent, EGR Vacuum, VRIS1, VRIS2, Purge Control, PRC, Cruise-Control, Fuel
Pressure Regulator and Airbox). Silicone hose is available in various colours
for location identification and tolerates far higher temperatures. The size
required is 3mm bore and 2mm wall.

Replace hoses one at a time by twisting them off, pulling will break
the plastic fittings on solenoids particularly at the rear of the engine. Verify
the hose from the EGR solenoid down to the EGR valve on the back of the transmission
area has not baked dry & split - these are subject to radiant exhaust heat.
