Thread: Fuel leak

The genuine filter is made by Baldwin, which is also Fuel Manager and another brand that eludes me at the moment, made in the U.S.A

Unlike for a Defender TDCi, the D4 filter isnt available as a Baldwin/Fuel Manager.

My Def weeps when near full parked on a f-r slope.

There is a fault in the joint on top of the tank.

When down by 15 litres or so, all is fine.

If its a Defender TDCi (2007-2016) there is a one way breather that allows air into the tank, the valve gets jammed and as the vent is lower than the filler neck fuel leaks out until the level is lower than the vent.

I route the breather to the top behind the filler neck.
The vent has a loop plastic tube on the end of it, depending on what shift built it (thats my guess) depends on if its directly on top of the tank, just off to the passenger side wheel arch, or on the drivers side just above the chassis.
The later revision of the Defender TDCi they routed the vent to the same spot behind the filler neck.
