Howdy all. I'm wondering what the flow rate in PSI's would be on a stock replacement mechanical Y-Block fuel pump?

As I'm sure many of you have read, I'm building a gas injection flame thrower for my 56 Vic. I have come across a diagram that claims that you are able to run a t fitting from near your fuel pump directly to the solenoids that direct fuel to the nozzles at the tips of your exhaust.

I'm having a hard time believing that the same pump that is flowing to my carb could simultaneously create enough flow to get a good spray from the nozzles, especially being mechanical & likely low flow.

Thoughts everyone...

Since the pre 57 Y still used the Holley 94 style carb pressure was limited to around 3# max.

286, are the later pumps better and did they change the mounting flange from 55-62?
