Fuel switch/gauge/pump wiring help

[GraficO]

OK... is this drawing correct if I want to by-pass using the centech harness wiring for the fuel senders but add the following?:
- use the stock gauge
- use an electronic fuel switch instead of the manual valve
- use the stock fuel switch
- run either the AUX pump or the MAIN PUMP using the dash fuel switch
- get MAIN or AUX fuel sender signal depending on which way the switch is thrown

Just want to make sure I'm not seeing purple monkeys

I would like an expert opinion on if the posts on the fuel selector switch are correct as well

I feel they are correct. But Viperwolf is the grand master

IF you are using a carb you only need one pump hook it to the single outlet of your switched valve run the pump off a relay switched off the ing.,on, side,run a new wire for the switching valve,run each tank to its appropit side of switching valve,keep both centech tank wires use them for each sending unit only,if you want a simply safty switch for electric fuel pumps use a 5-6psi.switched on hobbs preasure switch tapped into your engine oil presure,that way the pump only works when the engine is runing.Fewer parts.

that should be fine.

Looks ok to me also. Make sure the IVR is grounded.

The logic looks right, but that diagram doesn't show any fuses. And I wouldn't pull the FP power through the ig.sw. - a relay would be better.
