won't start after filter change

Hey guys,
being self-employed with no work on at the moment, I haven't renewed my membership, so can't access the fact sheet that may help me out...
I recently changed the air and fuel filter on my diesel (can't get the sump plug off for the oil change, so it looks like I'll be getting myself a pela pump)
So, after the filter changes, she initially started up alright, but then when I was about to drive to Machine Mart to buy a PelaPump, the Bongo started losing power. When I kept the revs up she would turn over ok, but then when I let them down the engine would just choke and cut out.
Now she won't start at all, even after a good crank to make sure that the fuel bleed ok after the filter change.
From having a good read I guess the first thing to check will be the Banjo Filter, but like I said I don't have membership/access to the factsheets at the moment because I'm broke (which is why I can't just take the bongo to a garage!).
If anyone could maybe describe to me where exactly to find the Banjo to check it/give it a clean, that would be awsome, otherwise I'm open for tips on what else to check...
One other thing, the time that it did start up there seemed to be a steady trickle of fuel coming from the screw cap that fits to the fuel filter, from what appears to be a overflow hole(??).
Thanks a lot in advance everyone...

PS there were no problems at all before the filter change

do you mean it was leaking from the bottom of the fuel filter from the sediment drain? sounds like it needs tightening up, there shouldn't be any dripping or leaking (check it isn't cross threaded) - did you fit the o ring correctly & put a smear of diesel on the seals before tightening? did you fill the filter with diesel or injector cleaner?

well, i didn't fill the filter with any diesel or fluid - i didn't know this was necessary (still getting to grips with mechanics)...
yeah, it was leaking from the screw in (thing) from that goes into the bottom of the filter, but the leak wasn't coming from the thread, it was coming from a hole (part of the design) in the screw in thing, and by the looks of the mess on the drive way (whoops) it appears a fair bit of diesel came out...
Thanks again,
T

Can't add much except to say I've done two fuel filters in the way Kirsty describes with no probs. I can't think of any particular reason why the banjo filter should play up just cos you changed the fuel filter so my first suspect would be something to do with the way you fitted the filter. Should hopefully be corrected without too much drama. Good luck - keep us posted.

That's the drain hole. When the white plastic sensor is fully screwed into the filter, it seals the hole, so it sounds like its not fully home. Was the new filter slightly shorter than the original & did you get the correct part?

Yes it sounds like you may not have screwed the sediment sensor back in place. My guess is fuel will then pee out until or unless the pull of the pump drags air in through the hole and aerates the fuel? Bongo would not be happy in that case, nor would the road surface

nice one, all good now...
yep, was down to the white sensor, like i said, the fuel was coming out of the drain hole, so made sure she was on tight as...
tried firing her up once, didn't start so i didn't keep cranking, then my brother in law just came out and cranked her til she started.
lesson for the future then, if fuels coming out of the drain hole we know the problem...
now i can go and get a pela pump (the sump has totally rounded off and is stubborn as hell even after filling the sides down) and would have completed my first full filer change, though in hindsight, with all the bits i've bought would have been cheaper just to take it to a garage, but at least i've learned a few things and feel more confident around my engine...
cheers for the help as always guys...

Greater sense of achievement doing it yourself plus sooner or later it should save money. You'll love the Pela - makes oil changes a cinch. Thought I noticed recently they were being sold for around £30 - good price if so. You could offer your services on the grapevine doing oil changes at home for cash

Glad you've got it sorted.
I used a Pela the other week & had very low expectations. It's quite slow & requires regular pumping, but at the end when I undid the sump plug to see what was left, all that came out was about 5 drips. Very impressed. Two fiddly bits: gauging how far down to stick the tube (too far & it will come back up the other side of the sump) & also its difficult to see the level of oil in the Pela sphere. I've got the 6 litre model & it definitely all fits!

Slow, but not that slow when engine oil is warm and you can do other stuff while it is pulling the oil out (though you need to re-pump at intervals). But its clean, convenient, simple. Easy to sense when you've hit sump bottom with the tube if you hold it twixt forefinger and thumb to sense the impact. Watch out on the 6 litre thing. I thought I had that taped until on once change it went a little over and gooed up the pump itself, which was messy to clean off.

read a fair bit on here about extraction vs traditional sump dump re: oil change.
The arguments against the pump method seem to centre around the point that any bits of gunk and crunk will be left at the bottom of the sump. However, most seem to say that by giving the motor a good drive and heating up the oil this will suspend the crunk, is that right?
Is it worth adding anything to the oil sump to aid a flush before I change the oil, or will I be alright just giving it a good warming up before hand and then quickly pump it out...?

I did not see anyone mention about priming the fuel pump (the big flat button on top of it)
Or did they?

Never had to prime mine, other than filling new filter with fresh fuel.

The priming button seems to a very rare item - they do exist, but I've never seen one. Unusually for a diesel, the Bongo doesn't seem to need priming.
