Final update and tips.
After trying to source the red clips at, Ford dealer, Bosch,Lucas(no reply from OEMs) , Northampton Autosports and Fuel Parts Ltd I drew a complete blank. The Ford dealer and the two spares providers all advised the clips could not be procured separately and the only way to get them was to buy a pump with clips fitted (£50 for 2nd hand pump up to £280 for a new one). The scrap dealers would not sell clips separately because if they sold clips they could not sell pumps without them! On ebay I found a guy trying to sell just the sender. After dialogue he sold me two cut off fuel pipes with clips and seals attached . (Photo in last post. So my choice was buy a new pump (if I wanted "new" clips) or fit the ones I got scrap for £6. I decided on the latter.

Removal and fitting. Ford apparently have a special tool but it can be done without. The sequence is imperative and cannot be varied .
REMOVAL: Using paper clip wire I eased the three tabs (top and each side (there is not one on the bottom against sender) "OUT" for me this was counter intuitive. However by easing them outwards it allows you to pull out the pipe from the red clip connector lock (Arrowed in picture above). Then you push the same three tabs "IN" to release the red clip from the pump housing. Then you have to pull out the two O rings and spacer washer left in the housing.

Assembly:
Put the Seals and spacer washer in to housing recess. (Ensure soaked in clean oil for later insertion of pipe, (sequence Brown seal first then washer then Yellow seal).

Insert red clip into housing with the flat on the outer circle at the bottom next to housing. The clip clicks into place. This also lightly compresses the seals just fitted.
Lubricate pipe end and coax the pipe through the red clip and carefully through seals and washer.
You the push the pipe hard into housing until it also clicks in the red clip. (no gap between clip face and pipe end face).

This final act locks the pipe into the red clip and the red clip into the housing. Job done.

All tested and all OK. The high pressure test on the fuel return line is when the engine is idling.

Anyway for the experienced Morganeers this is probably "old hat" for me its been a real pain in the a**e!. Hope it helps somebody?
