I started this thread but do not keep track of my Mileage. I am happy if my Car is working and drivable.

Hello, found this thread in a search and have a couple questions: Which component on the OM617 is referred to as the "lift pump"? The entire IP? If not, can someone describe it, or even better, post a picture?

Secondly, how exactly would someone measure the working pressure that is mentioned on this thread? Where are you fitting a gauge? TIA.

To find the Fuel Supply/Lift Pump locate the Plastic (Primary) Fuel Filter and trace it towards the Fuel Injection Pump. It is made of Cast Iron and has the Hand Primer Screwed into it and it has a hard Plastic Fuel line that goes from the Fuel Supply/Lift Pump to the Spin-on (Secondary) Filter Housing.
The Fuel Supply/Lift Pump is bolted onto the Fuel Injection Pump with either 3 or 2 little Nuts; Depending on the model of Fuel Injection Pumpu you have.

You would need to make a fitting to check the Fuel Supply/Lift Pump pressure. It would be best to find a DIY on it.

Also when the Fuel Supply/Lift Pump is working properly the pressure is controled by the Pressure Relief/Overflow Valve. The Valve is on the Engine side of the Fuel Injection Pump and is a Bolt that goes through the Banjo Fitting of the Hard Plastic Fuel Return line.
