My original thread which explains why i need to do this is linked below, but I have started a new one with a new title (you don't need to read the old thread unless you want to know why I need to release the pipe).

I need to release the fuel pipe (which comes from the filter) at where it joins the back of the high pressure diesel pump on 2015 fiesta 1.5tdci.  It is very very difficult to get to. I knew it would not be easy so I bought some of those pliers type things designed for the job. That does the job fine at the filter end of the type (although you can improvise without those pliers at that end as access is good).  

The pliers I bought are these  https://www.ebay.co.uk/itm/223067511607?hash=item33efdc1b37:g:H50AAOSwL~hbUGHt  . To try to make it easier I ground them down to make the legs bits slimmer and I also sawed two thirds of handle length off as the wiper panel was in the way of the handles. I have also twisted the pipe round at different angles but I just can not get the tool on both of the white plastic square bits that need pinching in simultaneously. 

I appreciate that it is not often anyone would need to release this pipe so maybe no one reading this has ever had to do it. If anyone has done it can they offer any advice eg. what tool they used (a link to it so I can see it?) and what angle they twisted the pipe to to get best access to the white pinch points and their angle of attack , from above, left, right, horizontal from the back (which is under some other bits which I don't know the names off).  After trying for an hour and having grazed fingers/hands I have given up and reconnected the old one at the filter end with my leaking pulse damper so I can still use the car (leak is very very minor at moment and I have an aerosol cap fixed below it with cable ties to keep an eye on the leak).

Any advice please - maybe from someone in a Ford garage?  although, as I say, I don't know how often anyone would need to release that pipe at that end so maybe no one has mastered it.
