hiya lads - given the lack of timely responses.......
I decided to think about what I was doing and not just follow instructions - amazingly, and for once, that helped.
so.....i loosened the sender thing one half turn, so it showed it's arshe to me and I could see how it clipped on
i took over 3 hrs but that was cowardice and inexperience
i've had a good couple of runs out, topped it up a couple times - really pleased with myself
biggest problems were as listed above
and......when i tried to loosen/chisel the clip on the underneath/hidden hose, I knocked the plaggy pipe off the old stat....no biggie.....but I hadn't realised and it took me about 10 seconds when reconnecting to suss that i was trying to connect a snapped plaggy pipe onto a plaggy pipe
the clips were a faff and I suffered from not having quite the right bits and bibs in my toolbox......but...i did it
I'm changing the clutch tomorrow
