You should mount the injector pump as close as you can to the tank, below the level of it.
The Bosch pumps do not like sucking (although they will) and do not do it efficantly, especially through teh long run of pipe from tank to engine bay.
They are roller type pumps and are designed (as are almost all injection pumps) to use the fuel as lubrication/coolant. Even running for half a second whilst fuel is being drawn up to the pump can shorten the pumps life drastically, as well as teh fact it's having to work hard to draw it from the tank.
Fit it close (& below) the tank, or use a lifter pump (such as a Facet Red top) to bring the fuel from the tank to the engine bay injection pump. - Again the Facet should be mounted close to the tank as they do not like sucking either.
ill be doin this over the weekend into my carbed nova, ive been told i can use the existing tank as it has a fuel return pipe but ill need to fit the pump near the tank and ill have to fit the hi pressure lines
where doe the pump need to be mounted at the rear and is this just ignition live and earth to make it run correctly???
Also a pic of the pump and its location if anyone has one would be ideal!!!
Cheers and sorry to interupt your post mate!!!

OK i got that pump of the astra 1.4 but it was a SPI. Will this pump be able to supply 3 bar? (pressure stated in haynes for the nova GTE fuel injection system) they had just crushed the 1 with the MPI 1.4 this morning but the pump i got works and shifts a suprising amount of liquid (tested in kitchen sink [mum will be pleased])
