Testing diesel fuel for water content

Dieselcraft Fluid Engineering has introduced its Fuel Test #W-1, an early warning system to test for 200 ppm suspended water in diesel fuel, jet fuel, kerosene and gasoline.

“It tells you water is suspended in the fuel and near the point where it drops out and becomes free water then causing major problems,” the company said. “Results are immediate.”

The kit consists of one 2-dram glass vials with the reaction powder capsule in it and one transfer pipette. According to the company, follow the following steps to test fuel:

1. Remove the capsule from the test vial.
2. Take a fuel sample from any location in the fuel system using the supplied pipette.
3. Add fuel to the empty vial FIRST, 3/4 full.
4. Take the capsule and open it by pulling off the colored half. The catalyst is in the clear portion of the capsule. Pour the continents (white powder) into your test vial with fuel. Put on the lid and shake for 10 seconds.
5. Set the vial on the table to allow the mixture to settle and examine the results. 100-200 ppm water will give you pink spots in the white powder. More than 200 ppm water will turn all the powder hot pink.
6. If you have more than 200 ppm water in fuel you need to take action.
