Has anyone got a diagram of where everything connects to on the metering head? The injectors and cold start are obvious but i'm not sure about everything else. What size pipes do I need for fuel lines, flow and return? Does the accumulator need to be near the metering head or can it be at the back of the car?

You'll have to excuse my ignorance, i've not had much to do with old MFI systems. The engine is going in a kit car i'm building, I trial fitted it a while back and made the mounts etc but now the chassis is all painted it will soon be getting install properly.

Thanks in advance

Hello mate,

When I did mine I was told to 8mm fuel pipe for the flow and return. The circled pipe in the left of the pic is the fuel feed from the accumulator which you can mount close to the metering head. I don't think outlet A dose anything although I'm sure some one will correct me if I'm wrong, outlet B will need to go your cam cover breather and C goes to the amil valve. D is cold start injector and E is fuel filter.

Hope this helps

Adder

Thanks Adder thats great. It pretty much ties in with what I was told on another forum, only difference is I was told the circled one was the fuel return
