Thread: Diesel Fuel Leak

Check around near the welds on the metal fuel lines. I bumped one of my metal lines while doing all my engine stuff and it must of fractured and created a tiny leak - I've since bypassed the metal lines completely. The lines I'm talking about run from near the fuel primer down towards the fuel injection pump, they've got a couple of tabs welded onto the metal lines where they're secured against the engine etc

Well after 6 months the culprit has finally shown itself after my Freelander started marking its territory in a big way with diesel.

The fuel return lines from the injectors have perished. The small hole that was not previously obvious got larger and allowed a visible stream of diesel to squirt out with each pulse of the injector pump.

This issue first become noticeable in about May last year as my fuel consumption seemed to be marginally increased. Later in about July I could smell diesel bit despite searching and searching I could not find the leak - even looked at the rubber hoses but all no avail. Finally the hole is now large enough for fuel to be visible being being pumped out and drip onto the ground.

So - I guess the moral is that check your rubber hoses on a regular basis particularly if they are carrying fuel and in a hot area.
