Run a jerry can from in the bay to the carb (you can dump both the return - if fitted - and the feed into the same jerry can) to see whether you have a blocked line under the car or a knackered fuel pump.

Try it to rule out blockages - can you see any flattened pipes at all underneath?

Is the cam running the fuel pump ok? Push rod ok?

Sounds like you've been really lucky then!

Usually without the spacer on either the pump won't fit.
The pump diaphragm gets mashed to bits.
The rod gets mashed to bits or the cam lobe gets mashed to bits.
