fuel tank sending unit problem

[70SS454]

Where the hell can I get a dual feed outlet sending unit for my gas tank to handle fuel for the engine's pump and one for the dedicated nitrous fuel pump.

My installer basically trashed my sending unit last year.

for a stock fuel tank ? don't really know but why not just add a sump?
or better yet just add a small tank up front for just the nitrous fuel supply.
I thinking you want to keep it "stock" appearing with the dual feed unit but when you "get on it" the fuel will rush to the rear of the tank and possibly run dry.
