My car is having a problem with fuel delivery. Fuel pressure is at 50lbs at idle but drops to 15 lbs when the accelerator is pressed. The speed shop was asking me to explain the function of the component behind he passenger side rear wheel is. My assumption is that the fuel pump behind the rear wheel (pictured) was for fuel return to the fuel cell, and the fuel pump on the rail under the drivers door (not pictured) was pumping fuel to the engine. The vertical aluminum cylinder in the picture that has fuel lines entering and exiting, I assumed to be a point of fuel accumulation to prevent fuel starvation issues. The speed shop I am working with has never seen this configuration and is questioning my assumption but has no theory on the components function. Since my Butler/Fodge Cobra did not come with any documentation, I was hoping someone on this forum might have insight to what this is.

Thanks in advance!
