Im just about ready to drop a 200tdi into my 90 with a 19j engine. Could anyone give me some instructions with the diesel pump pipes. do i need to change the filter housing and what pipe goes where?

Hi. I have a 90 2.5 TD and am in the middle of re-building a 200 tdi to drop in. One thing i am not sure about is the glow plug timer wiring. Has anyone got a clear diagram of how to wire the timer up. Many thanks Billy
