I have something similar on my Z. But it is pretty inconspicuous on the back of the engine almost obscured by the distributor. I think Jake is looking for something less conspicuous, given that his only available source is at the very front of the intake.

A Block Coolant Drain Plug removed may offer a nicely out of sight location for whichever fitting is easier to adapt?:hmmm:

The hole size is much smaller and a reducer bushing would need to be used, and I don't think the bushing would be deep enough for the electric sender.

I was just out looking at my 409, Jake, and the only other possibility I saw would be a T at the intake for the 5/8" heater hose for the electric sender. Seems to be room around that area for this, but I only have a single carb, so no reference for clearance to the 2x4.
Dorman does have a straight neck cover. I have one similar on my '38 for the fan controller.
