Hi there does any one know how to connect these turbo carbs


No 1-- Is the blow through where does it connect to ?
No 2-- Is main fuel
No 3-- Is Regulator


My first question is where do you connect the fuel return to ? (on the carbs)
My second question is where so you get air to pressurise the blow threws?

It got me stumped these are DHLA4 H carbs

According to the alfa mecs it needs a high pressure pump

It's carbs, there is no fuel return.

I'd say you need to connect the #1 connectors on the covers of the carbs to manifold pressure, to get the right pressure diff in the carbs. Dellortos right?

Ok kewl that makes sense there is that blocked off pipe ontop of the manifold I will connect that to the blow through should that be enough pressure ??

I would think so. Have never dealt with turbo-carbs myself but that's the info I have. Make sure you try everything outside and with an extinguisher ready.

No, I'm not joking!

Ohyes I always do

I had an episode with my ford sapphire wasn't nice belive me it was fuel rail ->distributor -> fire runnning around -> can't find extingusher, I found a 20lt drum of dish washing liquid I put the fire out but the harness was toast
