Thread: Bee utey, Zavoli Zeta Help please

I just finished reinstalling my engine heads and I something is not right with the gas system. When starting on petrol and when at temp when the gas should kick in I get the out of gas alarm, I presume this is set off by low pressure in the tank?
The tank is full.
Whilst reconnecting the gas up I had 2 hoses left over.
From the Converter the gas hose splits to a "Y" piece, from this go 2 hoses that connect to the Gas Filters, after one of the filters there is the gas temp sensor piece and then a length of hose that connects to the end of left bank of injectors.

The other filter has a hose that continues to feed the right bank of injectors.
Then on the 4 injectors are interconnected, once we get to the end of the left bank of injectors a smaller diameter hose connects to a nipple and then loops over to the end of the right bank of injectors where it connects to the nipple of "T" Piece.
I marked this hose with a label RH injector, after I pulled it off, I realised it's end was only connected to the left bank.

Now I had 2 more hoses left, ! connected to the other nipple of the "T" Piece and the other hose to the inlet manifold vacuum nipple.
Could I have fitted the last 2 hoses on the wrong spots, ie the vacuum hose is actually supposed to go on the t piece for the injectors and vise versa?
On the Convertor how do ID the vacuum hose?.

The reason I ask is my systems injectors are attached to the original fuel rail and the plenum covers all the injector hoses etc. Neat looking but hard to get to the gas components.

I found the pressure line from the MAP to the injector bank was clamped down flat under the plenum body, so no gas would have flowed through it.
unflattened it and now running on gas
