Check the 18RG tractor thread, there were photos put up by the Witzl quite some time ago with full explainations.

I have looked at threads but my ECU is very different to the ones pictured.

Any help would be appreciated

What ECU are you running?? Most modern ECUs can dispense with a lot of the factory stuff (which was because the ECU was based on resistors etc to determine a 555 timer frequency etc)

First photo:
E fuel return to the tank
F goes to plenum

Second photo, fuel supply from the pump

Third photo, I am blocking off for mine as it won't be necessary

Fourth photo, they are explained I believe in the 18R-G thread

Fifth photo, goes to the throttlebody (either water outlet, the other water outlet on the throttlebody goes between runners 1 and 2 into the inlet manifold flange) I will not be using this on my car.

Plenum ?????????????? What is this ....

Any ideas on A B C..

I am running Factory ECU. Also there are two hose outlets on the water temp housing where do these go ????

can't tell you about factory vacuum plumbing, I am ditching all of mine. Plenum is the big box between the throttlebody and the runners. It has EFI embossed on it.

Where does F go on the Plenum. I Have worked out C it goes to water housing and the other side goes to the dizzy.

This thread, turns up these diagrams which should help you piece it all together!
