Cant i just use some regular injector pipe?
You can use whatever you want as long as it's diesel proof.

It's a matter of safety, you don't want the pump running with a dead engine in the event of an accident for example.
Grit Valve

ok been out back looked and investigated like you say position II will use relay and drop it when ecu feels fit via glow plugs yes there is a section that says rhe diesel fuel pump will not be activated on diesels untill it recives an out put from alternator , fuel pump (109)but also says from position three starter will activate it doesn't indicate years as I have read both 97 and 99 onwards they seem identical to me . No matter what it says if I turn over the cars when the glows have gone out they both squirt fuel that's why I asked earlier what is the differance between a started car and one being cranked as the ecu must still be reciving info from both scenarios ?
The way I interpret it is you turn the ingnition switch on to position two the system is primed and the pump and glow plugs are deactivated the pump will not be running there after no need as fuel isn't needed until this is my point the engine is being cranked or is running either of the last two reactivate the pump as fuel will be needed thereafter.

My multi meter showing the black are both earth the white with blue stripe is 12v live with glow plugs and the green carrys 5v live?
So unless somthing seriously wrong the pump is getting power but not running?

The connection also has the Fuel Level sender to it hence the 4 wires...

Power to Sender (5v Line voltage)
The Lift pump is a common fail item....

You need some Plus gas on those matey.
Look at the wiring diagrams posted by Ant. Follow the circuits see where they go and count the diodes on 97 version then follow the circuits and count the diodes on 99 version. Lift pump on with cranking did not come in until MY 1999. Simple as that.

Been soaking them in wd40 for about 2hours still solid can the pipe be cut and new conectors used or isnt there enough slack?

WD40 is a water dispersant, the clue is in the name, useless for freeing things, you need plusgas

It's pretty good at freeing stuff though; am I about to get some better lubricant and find bolts basically just fall off with ease?

Yes. Petrol is a pressure pump diesel is a lift pump.
