Sounds like if you port the IAC passage, the whistle goes away. Now is the time.

If the IAC is the cause, then it's easy to tune out via a throttle plate adjustment with an aftermarket ECU. The factory is concerned about emissions at idle, but Holley, Haltech, Megasquirt have a sticker that says 'this does not comply to federal emission standards' LOL. It's easy to idle with more or less throttle with timing changes - makes your exhaust a little gassy smelling at idle - much like a carburetor can do. It can be done with HP Tuners also, but only if you have the software.

Holy smokes! That thing is 3 beans?! The wire colors say "Spectra", but their pump mount isn't on that jaunty angle yours is and the pickup isn't angled either. I wonder what the application is, even though Spectra went under. My GN sender is straight down.
Nope. You see a pressure feed and a vent line. The return is internal to the sender so it dumps right back into the tank, no external line required.
I've been wondering why they have it at an angle too. Wondering if it's just to reach the "back" of the tank so under acceleration the hydramat has fuel around it?
This forum is the best place! Huge shout out and thank you to 64nailhead ! He sent me a throttle body for my build. My spark plug wires and flywheel also came in.
