Here is a shot of the stainless tank. You will see the battery box at the rear so the battery is recessed into the tank. Not only that but the Bosche EFI pumps are recessed too. Basically, the outer dimensions of the tank will include all fuel elements and the battery (so the EFI pumps, lift pump, surge tank, etc all recessed into or actually inside the tank.
This way, I just bolt up the tank and there is nothing else to make room for in the trunk. I can just install the tank and connect the fuel and electrical lines - and i'm good to go.
Something that may be of interest is that i'm going to use a PWM output from the EFI management system to provide an input signal to a solid state Hella relay. This will allow me to send a signal to EFI pumps to moderate their speed/output. This is a good thing because it stops the pumps running flat out even at idle (and churning up the fuel). The PWN output is variable based on a map of engine load and RPM. More on this when i finally wire it up.
Now here are some shots of the custom manifold adaptors i built up to convert the circular throttle blocks to the oval ports on the A460 heads. This first shot is from above and shows the 65mm thickness that provides me the port transition required and the 14mm diameter injector bosses.

The photo below shows the head face and the bolt holes along with the coolant ports.
These units have come up beautifully. For anyone local in Australia, i got these machined up at Flexicut in Dandenong by Robbie (owner). It took me quite a while to find a place that had the auto background knowledge and the interest in such a one-off project. I can't recommend them any higher.

The following photo shows the circular inlet compared the oval outlet above.
The coolant outlets are AN-16 thread machined for O-rings.

And the 3 photos below show some test fitting of the injectors and throttles.
Notice the throttle shaft comes close to the injector, but there is room for a throttle position sensor (just) on top of one throttle block. I'll just have to include some little extensions on these injectors o raise the fuel rail to clear everything. The number 1 priority was to get the injector position and angle right - and fit everything around that afterwards. I'll trim the top of the shafts later and create some cover plates to make it all look good.

Of course now i need to sort out my trumpets without having one cylinder steal air from another.....
But it's going to look good and flow plenty of air once done i believe.
And there is the small matter of all the linkages, bell-crank, etc. Yet another mini project that will take time.
