[my427cobra]

OK. Help me undestand this :
The original 427 cobra street models used a mechanical fuel pump on the engine and a single electric fuel pump in the trunk. Why two pumps? Was there a regulator on the system or was the electric fuel pump the adjustable version of the SW240 ( the 240A)?
If the electric pump failed, would the mechanical pump still supply the carbs? Or visa versa?
Why am I asking? Well , I'd like to replicate the street set-up and I was curious.
