Fuel Analysis Tools

Taking fuel samples from the top of the tank is easy, but won't give an indication of the extent of any contamination...water is heavier than fuel so it sits at the bottom of the tank.

Our Tank Check unit will help you take samples from the bottom of your tank, either on the tank floor, or in small distances from the bottom. This will help you identify how much water has accumulated in the tank, and the extent of any diesel bug contamination. Results of these tests can help you decide if the diesel would be fit for use after Fuel Set application, or whether you need to pump out as much of the contamination as possible. 

Tank Check is a must for any company or organisation that keeps diesel for long periods, or is at all concerned about the potential damage to engines caused by badly contaminated diesel. We recommend that tests should be carried out every 4 – 6 weeks, depending on throughput of fuel and whether there are any critical safety issues.

N.B. Tank Check can be used to sample any liquid EXCEPT petrol. which can affect the plastic part of the item. It IS suitable for use with diesel, wine, beer, pond water, domestic heating oil, etc.


In addition our Water Detection Paste, available separately, also identifies the extent of water contamination in the fuel. It is a simple colour change indicator, and very easy to use in both petrol and diesel.

If you are in any doubt, or would like a professional opinion, please call Liquid Engineering (UK) Ltd. We would be happy to discuss your problem, and even arrange to see/analyse your fuel.
