ham Posted November 24, 2014 Share Posted November 24, 2014 Anyone out there with any ideas. pulled out of out of town shopping centre, joined the M4 and heavy smell of diesel, so pulled of motorway next junction .Opened the bonnet and Diesel pouring out of the fuel pump . Turned engine off and flow of diesel stops, had a look at pump fuel lines appear to be ok and in place. Pushed and pulled them. Restarted engine no flow of diesel . engine running normally ,so what was it? Having driven 60 miles back home looked at pump again and notice just an odd drop of diesel running down side of pump... the van is Fiat ducato 2.3 2007 Link to comment Share on other sites More sharing options...
euroserv Posted November 24, 2014 Share Posted November 24, 2014 Hello.. Fuel leaks on these engines are extremely rare. It is most likely the seals on top of the pump and this is not a DIY job. You will need to clean the area with Jizer or something like that to get rid of any oil and fuel residue that has accumulated and get it to a Bosch diesel specialist. They may be able to repair it in situ but more than likely will have to remove it and replace with an exchange unit. The job of replacing a pump is a big one and involves removing the timing belt; so you will need to have that replaced at the same time. If it's a forward thinking dealer they might have a go at a repair. Fingers crossed. Nick Link to comment Share on other sites More sharing options...
lennyhb Posted November 24, 2014 Share Posted November 24, 2014 Are you sure it is the pump and not the fuel filter, common fault on early X250 was a split fuel filter housing, the symptoms you describe is just what happens when it's the fuel filter housing. Hope it is the filter if it's the pump it could add a couple of naughts to your bill. Link to comment Share on other sites More sharing options...
euroserv Posted November 24, 2014 Share Posted November 24, 2014 Hi Lenny, OP said it was coming from the fuel pump. I too hope he is mistaken! Link to comment Share on other sites More sharing options...

I did read it right Nick, I was just making sure he wasn't looking at the wrong bit. Link to comment Share on other sites More sharing options...
ham Posted November 24, 2014 Author Share Posted November 24, 2014 Thanks Gents. Nick It looks like the fuel pump, green plastic fittings sitting in a black plastic container. The fuel is visible on the top part of the pump. I suspect one of the pipes may be loose as there appears to be no clip or strap holding the connection pipe. I had the belt changed last year so that’s no problem looks like a visit to the Garage .Thanks again Link to comment Share on other sites More sharing options...
Billggski Posted November 24, 2014 Share Posted November 24, 2014 The fuel filter is a black plastic container with green fittings, but is top right as you open the bonnet. As mentioned it is a common fault as the housing becomes unscrewed and fuel leaks through the o-ring that seals it. My leak was fixed by an Irish mechanic with a hammer and chisel! Still good after 4,000 miles. Link to comment Share on other sites More sharing options...
ham Posted November 24, 2014 Author Share Posted November 24, 2014 Looks like the problem is the filter. I called into my local car garage to book an MOT for my car. Got them to have a look then both laughed no it’s not your pump it’s the filter so tomorrow when it’s light I can get it checked out. Glad I did not let the garage in Bridgend loose on the van . Shame my local garage is to small to accommodate vans just only cars Again Thanks for the help. Blood pressure back to normal now :-D :-D Link to comment Share on other sites More sharing options...
witzend Posted November 24, 2014 Share Posted November 24, 2014 Those filters aren't straight forward to change google it they have been a problem for a lot of people but not as expensive as the pump Link to comment Share on other sites More sharing options...
Arthur Brown Posted November 24, 2014 Share Posted November 24, 2014 Advice from Nick when I asked the question was to get a new filter. They come complete with filter, assembled and ready to snap on. Fuel lines (2) are quick fit connectors and there is two electrical plug/sockets. Mine leaked three times and it was 'fixed' under the warranty. I might add that it is a 2011 registered which means 2010 or even 2009 chassis Fiat. The last time it happened I took it to bits, cleaned and dried it and greased the threads to remove the friction between the plastic surfaces. Put it together and so far, touch wood, it is ok. However, I took Nicks advice and now carry a brand new filter complete. I got mine for £62 including VAT but they can be that plus VAT or thereabouts. But FIAT do not have a problem, it is all in our imagination. Hope you get sorted but it is a job any reasonable DIYer can complete. The other job is to clean the mess off the nearside paintwork.

Billggski Posted November 25, 2014 Share Posted November 25, 2014 The garage that did my service, and therefore changed the filter, said the torque applied to screw the filter bowl back on is critical, but I've no idea how you measure it. The aforementioned Irish mechanic took it off a few times by the roadside in Dublin, and as a final attempt to get me to the ferry, banged the thread tight with a hammer and chisel. It worked and when I took it back to the garage, they checked it and it wasn't leaking and looked intact. So, figuring that it won't need changing for a couple of years I left well alone. Not recommended, except as a last resort. Link to comment Share on other sites More sharing options...
ham Posted November 25, 2014 Author Share Posted November 25, 2014 Yes it was the filter. Thankfully My Brother who is a Fitter had a day off work. Last night I wiped the casing of the filter clean and it was still dry this morning, I checked the filter this morning with the van running and no leak evident. Unlike yesterday it was pouring down the side of the filter. So Brother tightened the filter casing a touch, and on checking the return pipe it appeared to be loose and it looks like this is where the problem is. So a new filter on order and a new clip to retain the pipe . but will leave new filter off until Van is serviced in April 2015 or change if the problem reappears has I do not expect to be doing much mileage this winter. Thanks again for the replies. Link to comment Share on other sites More sharing options...
lennyhb Posted November 25, 2014 Share Posted November 25, 2014 It is usually the filter housing that cracks, just a hairline crack often only shows up on long journeys I assume the housing gets warm and the crack opens up. Happened on my mates van drive a 100 or more miles stop and fuel pores out, just drive it a few miles, no leaks. Could be worth giving it a closer inspection or as you have ordered a new one fit it anyway. The design has been changed so shouldn't get any problems with the new one.

Arthur Brown Posted November 27, 2014 Share Posted November 27, 2014 Hi Mine was replaced to the recommended torque using the special tool. I watched the man do it and it still leaked within two weeks. On the next occasion when I did it I used the bicycle type chain oil filter removal tool and tightened it as tight as I could get it. Six weeks and ok.. I suspect that the tightening procedure is troubled by dry plastic rubbing against dry plastic so I put grease on the threads. I also suspect that it comes loose as a result of vibration. The filter bracket allows the filter to move and vibrate when the engine is running and rattles the filter loose. May be wrong but in the absence of any other excuse it seems reasonable. The torque requirement is very loose in the grand scheme of things, from memory thirty something. The science is so vague that I carry a spare filter housing complete. Hope this helps those who may otherwise not carry a spare. Art Link to comment Share on other sites More sharing options...
