I am aware of the problems with the fuel filter housing on this model, 2012 120, 2.3l, and carry a spare assembly, never had a problem until today.

The filter was replaced properly by @dave newell lvs in July last year and is still within it's service life.

There was a large leak from somewhere on the filter housing just before I parked up, stopped the engine and diesel dripping everywhere, went into store and did a bit of shopping drove back to site, aprox 5 miles and no sign of a leak.

Does anyone know of a possible reason for this other than filter housing failure, seems strange to me that it has stopped leaking after what I would call a major leak.

Fuel Tank seam corroded leak stops when level is half a tank
drive up levelers tipping tank forward (Most likely place for a leak)
then tilt backwards if not found at front

Fairly sure the leak was from round the filter housing somewhere and stopped when I turned the engine off and didn't leak when re started!

I would hope not on a six year old van... But anythings possible.
Not many supermarket carparks have that much gradient.

If tank was over half it wouldn't need any gradient
I was offering a suggestion not a diagnosis

Would the diesel be likely to leak anywhere near the filter housing though, it looked as though it had been squirting out under pressure and it is fairly high up in relation to where I think the fuel tank is?

I started to smell it about 200m before I stopped by which time there was quite a trail on the car park and a puddle where I stopped momentarily to reverse.

Agreed Geo, and I wasn't criticising your reply but it would continue to leak after this event... (Every acceleration, brake and turn) Until it was below the leak point which would be more than a few minutes but the op said it stopped as quickly as it started.

I haven't had a proper look at it yet but over the weekend I will get my overalls on and clean around and investigate, don't need to use it for a day or two.

I had driven mine to Cornwall and back no issues. Daughter and family took it away for holiday and broke down on way! AA called first question when was it serviced, 500 miles ago, I know what it is was his answer. They arrived lifted bonnet and pushed the fuel feed hose back in, it had detached. Had no end of these was the comment from the AA guy who then checked every connection again. In fact as they had my grandchildren with them he zip tied all the connections to make sure all would be OK . Not had problem since, appears these connections can be troublesome. Hope it's as simple as mine
