OK - so I really should be working right now....but the sun's shining and its Friday afternoon - let me bring you up to date.
So, humbled by the brake fluids I went into the next day with some trepidation.
Firstly we plumbed in the line from the fuel tank into the front fuel pump. New hoses, new fuel lines through the tunnel.
Check all the connections at the back end - make sure that the hard lines under the arch are connected to the right bits on the fuel filter.
Check the jubilee clips.....we weren't going to get caught out on that one again....all good (pheew)
Put fuel in the tank for the first time in two years. Re-attach battery, turn on ignition (we're not going for a start). Keep an eye on the front pump - the O-rings have a habit of drying out. No leak there. All good.
Then I heard a kind of splashy squirty noise in the engine bay. We've got petrol pi55ing out all over the engine. Bugger. Surely I've not done it again......
Anyway, it turns out that the ends of the hoses that were on the MFI had perished over the last two years. Although they were new when Mike did them, the ends had dried and split. We had to replace all the hoses on the engine, they were all in the same state. Luckily, I had enough new line spare to do this. On a serious note, I was surprised that this had happened. But just goes to show that the rubber lines are something to keep an eye on if the car is off the road for any significant period of time (I'm thinking 12 months plus, but I have no idea when this set in and it was stored in my garage, which is cold and damp and draughty - none of which would have helped preserve the rubber)
Got the fuel filter off, took the top of the stacks off so we could get to the pump, replaced the hoses. Put everything back in order. (And frankly, I'd forgotten how stressful it is taking nuts and washers off around exposed stacks - it just takes a moment's carelessness....) But nothing bad happened.
Re-attach battery. Go for another half ignition. Pumps whirred. Fuel went along. Everything stayed where it needed to be. YAY!!!
Here's a gratuitous engine shot to illustrate the story needlessly. But I do love how the red and green work together

Must get a baby wipe to that dust on the air box.....
