Technical FIAT uno 1,1ies Bosch spi convert to manual choke carburetor.

Can someone inform me how can i make this modification ?
Besides manual carburetor - intake manifold -mechanical fuel pump - manual choke assembly do i need something else?
Is it a straight swap?

Your cylinder head might not have all the necessary bits to make a mechanical fuel pump work, in which case you'd have to go with an electric pump.

Steve145 thanks for your reply.
Cylinder head has a metal plate bolted behind cylinder 4.
Remove factory intake-unplug Bosch spi and bold mechanical carburetor and mechanical fuel pump?
Do i keep electric fuel pump(sender) inside fuel tank and connect fuel hoses to mechanical pump?
Do i leave cars Ecu connected to wiring harness?
TPS sensor gives me only problems.
I would like to do it myself for fun and experience of course.

I`ve not done it, but yes, in theory you can leave the in-tank pump where it is & just connect the pipes (tank to SPI to the inlet of the mechanical pump, pump out directly to the carb, and the return to the old return.

I think the SPi camshaft still had the mechanical pump take off, but check, either by whipping the cam cover off & looking, or, by taking the SPi mechanical pump blanking cover off of the head, placing a pump pushrod through the hole & seeing if it moves when the engines turned.
