Well got the front end done. All went very well. Instructions proved to be excellent and very detailed with some good tips. Tools required to remove the upper manifold - 8mm socket 10mm socket and some good long extensions.
If you remove the throttle body, you dont need to remove the water fittings arrowed nor the throttle /cruise cables.
Dont forget the two short bolts arrowed, they are easy to overlook
Arrows here show the positions of the coil bracket bolts. The lower ones are a real cow to see. A bit of touchy feelie required. You only need to remove the top ones - the bottom one just need to be loosend.
This stud is best removed to assist lifting the manifold.
Once on the bench, the manifold is drilled and tapped M6 to take the injectors - 8 in total for the cylinders plus 3 on the plenum for vacuum and vent.
Before refitting the manifold, fit the "cut" harness to the petrol injectors.This feeds the Gas ECU with signals and cuts the petrol injectors when running on gas. This is also a good time to change those plug leads to a set of Magnecors, otherwise access to the coils is tricky with the manifold in place.
The vaporiser fits on existing tapped holes - easy.
The refitted manifold complete with injectors and valves.
Cutting into the heater supply pipes to feed the vaporiser. I ended up cuting about 1.5 inches from each pipe to allow for the T and the shape of the pipes.
The finished job.
The ECU tucks very neatly in the space once used by the old GEMS ECU. The Bosch ECU is was relocated for some reason ( anyone ?)
Neat little switch / gauge. Notice it is offset to one side to clear the fixings. The cable is fed through an existing grommet behind the header tank, which is conviently clipped in position.
So far, it has taken about 14 hours to this point. The tank is next but at time of posting it hasnt arrived. I will follow up as and when it arrives.
