Many common rail diesel engine faults can be traced to fuel feed pressure or volume issues and electronic on board diagnosis (EOBD) cannot always pinpoint fuel feed problems accurately giving confusing turbo pressure or fuel high pressure circuit related fault codes. When used correctly the 7849 can quickly diagnose a fuel feed problem, as it has been designed to allow quick and easy diagnostic pressure tests to be carried out on the low pressure fuel side of a common rail diesel system with the ignition on and/or engine running. This kit can connect in to any low pressure fuel system that uses 9.89mm quick connectors and can also plug straight into existing Laser fuel bleed adaptor kits including 5262, 7174, 5566 and 5567. This allows the kit to be used on Citro�n, Peugeot, Renault and Vauxhall/Opel connectors as well as Ford, Jaguar and Land Rover. Diesel fuel low pressure and vacuum test kit with gauge. Fitted with clear pipes to allow easy indentification of air ingress. Supplied
