If you are not mechanically minded you may be asking what on earth this is. I certainly did until I had a conversation with MAN UK and I discovered that it was not something that you added to the diesel but in fact a system whereby the water that could accumulate within the diesel was seperated and able to be drained.
Looking to understand this more, a search on the internet lead me to Separ in Hertfordshire. A quick phone call and email to the sales department led me to speaking with an extremely helpful and knowledgeable Jayne Whiting. Special thanks has to go to Jayne for patiently taking me through the various systems that her company has and what options would be more suitable for our needs.
Decision made and we will now be able to expel any water that gathers within the diesel.
Thank you Jayne and Separ.
