rg1642 Posted October 2, 2016 Share Posted October 2, 2016 Hi, I am just about to get the fuel tank out to get to the fuel sender unit. So I look at the Haynes manual, lift the car, look underneath and there is an additional 'tak' of somesort betweem the tank and spare wheel well. It has pipes & wires going to it and I haven't a clue what it is. I have attached a couple of pics to see if anyone can identify it before I start work. Thanks Quote Link to comment Share on other sites More sharing options...

rg1642 Posted October 2, 2016 Author Share Posted October 2, 2016 Oh. Wasn't even aware it had a DPF. LOL It's never regenerated. Or at least neither me or the wife have ever seen any lights saying it's regenerating. It's done 10,000 since we have had it as well. I suppose there will be connections between that and the tank then to look out for when I take it out. Thanks for that :) Quote Link to comment Share on other sites More sharing options...
iantt Posted October 2, 2016 Share Posted October 2, 2016 yep, you can see the connector where you fill it in both photos. just under the red circle near the antiroll bar Quote Link to comment Share on other sites More sharing options...
simcor Posted October 2, 2016 Share Posted October 2, 2016 Can you not get to the sender from an access panel underneath the rear bench seat? Most cars have an access panel for that reason would be crazy to have to remove the tank to do it. Quote Link to comment Share on other sites More sharing options...

rg1642 Posted October 2, 2016 Author Share Posted October 2, 2016 Got to agree it's a stupid design. Suppose i could cut a hole under the seat until I find it ;) perhaps not LOL Quote Link to comment Share on other sites More sharing options...
iantt Posted October 2, 2016 Share Posted October 2, 2016 seen that before on a mk1 focus, they had used tin snips, the coveref with a tea tray , then put seat back. did amuse me. 1 Quote Link to comment Share on other sites More sharing options...

I was thinking of doing just that at one stage, before finding that Ford diesels do not have a tank pump. It is quite easy to find, on my car there is a big hole (over 50mm, from a photo), with a rubber grommet in it, right over the sender unit. But I was not planning to use a tea tray to cover it, maybe a nice bit of Ali sheet. On the other hand, I think I may have an old tea tray somewhere, perhaps I will retain it for future use 1 Quote Link to comment Share on other sites More sharing options...

Or does it???? That's the whole point of me taking it out. I've seen pics of the sender unit on some 2.0l models with a pump built in. Some say it don't have one some say it has. I had small metal shards in the filter when I changed it and I want to find out where from. The car runs ok (8k since I changed filter) so I don't think it could be the main pump, so I want to make sure it's not coming from the tank. It will give me a chance to treat any rust under there at the same time anyway so it wont be a wasted time sort of job even if I don't find anything. :) Quote Link to comment Share on other sites More sharing options...
rg1642 Posted October 3, 2016 Author Share Posted October 3, 2016 Well I just had Ford get back to me and it has a 'sender & pump assembly' listed. Surely Ford wouldn't get it wrong? Quote Link to comment Share on other sites More sharing options...
iantt Posted October 3, 2016 Share Posted October 3, 2016 ive searched extensively on wiring diagrams for your vehicle and cannot see any reference to in tank fuel pump. also no reference to one in the mechanical procedures. the mechanical procedure call the petrol version " fuel pump module", the diesel " fuel sender unit". I looked at replacement aftermarket parts, petrol £200 ish, diesel £100 ish. The sender unit assy contains an integral venturi pump., the returning fuel sucks up additional fuel into the housing. nothing electrical I obvious stand to be corrected and eat humble pie if I am wrong. ha ha . ive just never seen an electrical pump when ive removed them,( normally when some numpty has filled up will petrol) not that I'm looking in particular. if you remove the back seat and peel the grommet back you may see the connector and tank unit pins,se how may wires on connector and how many corresponding pins on tank unit I agree the info on the internet is contradicting. 2 Quote Link to comment Share on other sites More sharing options...

rg1642 Posted October 6, 2016 Author Share Posted October 6, 2016 Well the tank is out, the sender out and I can categorically say there is NO PUMP in the tank. Haynes manual is wrong, Ford dealer is wrong. This leaves me with one problem though. Where did the swarf in my fuel filter come from? The HP pump does not look new but it has run perfectly for 10,000 miles. Questions, questions. Quote Link to comment Share on other sites More sharing options...

I have heard quite a few comments linking swarf in the filter to fuel pump failure. But as far as I can see on my car, the inlet to the filter comes straight from the tank, there is no re-circulation connection. So pump swarf would go into the tank, and tend to stay there, as it is heavy. When you think about all the processes & movements that fuel goes through from refinery to filling station, I suspect there are plenty of sources of swarf & other general dirt, in that chain.

iantt Posted October 6, 2016 Share Posted October 6, 2016 the fuel filter recircs the fuel when fuel temps are under 15c internally on the 1.8 , im glad i dont have to eat humble pie after all lol Quote Link to comment Share on other sites More sharing options...
iantt Posted October 6, 2016 Share Posted October 6, 2016 the 2.0 does the same, but didnt know at what temp, just checkef and its the same Quote Link to comment Share on other sites More sharing options...
