Thread: Contaminated diesel!

When I built up this Hilux for overland travel, one of the first things I added was a Fuel Manager 100 diesel pre-filter with water trap and alarm.

Today, 6½ years later, the alarm went off for the first time.

Luckily it was just down the road from home and even more luckily I had just missed the special on the diesel at Gull, so hadn’t filled up. The vehicle has a steel Longranger 140L tank so that would have been a massive irritation. I reckon there’s still at least 60L in there. Hopefully I won’t need to drain everything out of the tank, just whatever contaminants are in the bottom. We’ll see.

Anyway here’s a couple of pictures of what was in the water trap, demonstrating that these excellent Fuel Manager products really do work. When the alarm went off we knew exactly what it was because it goes off every time you start the vehicle to test for circuit continuity. Bloody pleased this shit didn’t make it into the factory filter or even worse into the fuel pump and injectors…

now could be out here but we had a bad dose of diesel bug when I was at Lake Waikaremoana - hi lux stopped etc did look a little different - more like melting tapioca in the diesel - our supplier blamed a winter additive

Sudden cold hit in winter? Wax distillate dropping out of suspension? If that's the case it's 'summer diesel' with all the waxes left in suspension ending up in too cold an area, the wax drops out plugging everything. Pain in the arse, expensive on filters and the companies deny deny deny as when tested the diesel is fine - all excess wax has dropped out already!

yep No 3 that sounds very familiar
