Depends on what kind of pressure gauge you get. If it's a mechanical gauge then you'll have to run fuel line inside the car.... Yuk.

If it's an electronic gauge with a pressure sensor and a sending unit, then the only thing in the car is the wires. MUCH BETTER IDEA!

Of course, the electric gauge is going to be more expensive.

I would go with an electronic if you want it in the cabin.

Otherwise, just mount it in the engine compartment inline with the fuel line.

Since the pressure should be constant, anywhere along the line would be fine. So the spot you picked is just perfect. If you get a mechanical fuel pressure gauge, you can get an isolator so that gas won't be plumbed into the car. Or, as was already mentioned, you can get an electric one (they're just expensive).

I think that might be normal/desirable. Under greater load, you'd want higher pressure/more fuel going in. It's pretty much what those rising rate FPR's do.
