I have a 2.0 DOHC Sierra with a leaky fuel tank.

I've dropped the tank down and located the leak along a seam and I have a replacement tank waiting to go on.

I'm struggling to undo a connector coming out of the fuel pump/sender unit.



I can't see a way to undo it. There is a bit at the front with two holes in it that rotates independently of the rest of the connector. Do I need to push something in these holes to release the connector? I don't want to just go jamming something in there incase I'm wrong and I damage it.

Also, is it critical to use a new seal around the sender unit? I can't find anywhere that sells them and my local Ford dealer tells me they have been discontinued.

Yeah if you gently push the 2 bits of plastic you can see in the holes towards the centre. It pushes a locking piece out of the plug it's sort of horse shoe shaped. Very similar to fuel filter connections on more modern cars

The sender unit seals are on ebay

Thanks for that, I'll whip it off now.

I looked on eBay for the seals but couldn't find any. A search for "Fuel sender seals" returns 8 results and none of them are for a Ford Sierra. I'll keep looking.

Edit, found some for a Ford Escort Cosworth. Likely to be the same?

i need to do the same on my saff 2.0 DOC

got a spare tank which was from a cossie so it should be ok.

Anyone got a link for the sender seals?

If you found your tank strap had rusted through and don't fancy paying Ford for a new one (they quoted me Ł70-odd plus VAT!) B&Q sell 1m strips of steel that are perfect for the job.

I got one of those and bent it in a vice to suit using the old one as a guide, cut the excess off then bolted the ends of the original to that. Fit perfectly and only cost me a tenner!

I still haven't managed to find new seals though.

I'm beginning to feel a little bit silly now, I'm still unable to get that connector off

I tried pushing two very small screwdrivers into the two small holes at the front of the connector. Nothing happened and I could see inside that the plastic was beginning to cut/deform where I was pressing it.

I found two videos on Youtube about quick connect fuel lines connectors:

Would the same technique undo the connector in my photo?

luckily i dont need to change my tank - it was just the overflow pipe when you overfill.

Previous owner had put a new tank on - good job as the cossie tanks are different to these.
