Fuel Solenoid Port as Secondary Fuel Intake?

Fuel Solenoid Port as Secondary Fuel Intake?
Now, somebody somewhere sometime was talking about threading an auxillary fuel input line into their fuel solenoid port.
Has anybody actually done this and have we decided whether or not it would work?
(You see, I'm designing a custom dash, and I figure that it would be cool to keep the stock piston pump for regular use and then maybe have an auxillary electric pump threaded into the solenoid port. But, if I did that, then I would need three fuel pressure gauges instead of only one, which would mean that I need to design a more complicated dash. So that's why I ask...)

The VE will still require fuel for lubrication, so you'd have to leave the lift pump hooked up to the normal inlet. Other than that, it would probably work (with a pump capable of 150psi).

The VE's vane pump takes the fuel from the lift pump and pressures it up to a higher pressure. This high pressure fuel enters the case, and is fed through a passage in the pump head, down to a port to enter the plunger area. The fuel shutoff solenoid simply blocks the passage to the plunger.
So the question now is, what starves first; does the lift pump starve the vane pump, or does the vane pump starve the injection pump? Would anything be gained by bypassing the vane and going straight to the injector-head-thing?

You have to keep fuel to the vane pump for lubrication. It'd probably work to use the shutoff solenoid port as a secondary feed though.
