Yay!! Just got it all back together, and my car lives again!!
I can confirm absolutely a PITA job!!
For anyone contemplating slipping in a new fuel pump:
In case you don't know, first of all you have to disconnect an awful lot of of stuff; then to get the fuel tank out the front must be dropped first and then moved forwards to allow the filler pipe etc to come out of the gap in the bulkhead before the rear of the tank can be lowered.
Putting it back is done in the reverse order, but I had trouble with that @$%^& evaporative separator thingo.
I suspect it might have been easier if I had assembled the hoses to it first before I raised the tank and then fed it through the gap in the bulkhead along with the filler pipe etc.
I probably did it the hard way by not fitting it until after I raised the tank in place, finding it it very difficult to re - fit the 2 bottom hoses to it.
