Hood Deflector = Hood Bounce / Flapping

[Humper]

I installed the AVS ll textured hood deflector and man, the hood shake near the top edge (Winshield Edge) is crazy, I was scared to drive more than 60mph.
I have read threads about adjusting the bump stops, will do that and re-test and also inserting 1/4” fuel hose around the hood and the back “bulb”, for anyone that has done this, could you confirm this is the correct hose I need?

A 1/4" Inside Diameter, 0.490" Outside Diameter will work for easier fit

This pic shows a 2nd choice (5/16” ID, 9/16” OD) and some links that might still be good

Once Ford gets my windshield in, I am going to have one installed by the dealership, then if I have "bouncing issues" they will have to fix it.

Got mine to calm down a bit by backing out the bump stops completely(to ensure they were even when reinserting) than doing a full turn in until it stopped. I think the logic is when the latch grabs, the bump stops provide enough pressure against the hood to truly make the latch hold tight. ? Someone correct me if I’m wrong though.

I just installed the same deflector on my hood and have driven up to 80mph without any significant wobble. I must be lucky!

You must be very lucky, I honest thought my hood was gonna fly off it was that bad.

No issues

I had hood vibration before AVS deflector and I still have hood vibration after the install, it made no difference. I'll have to try and run a fuel line through the rear hood seal and see what happens.

I ordered 1/4"x5' fuel line for $6.99 off Amazon. I sprayed the fuel line with silicone spray and stuffed it into the rear hood seal and cut off the excess. I took it for a ride on the freeway at 75 mph, no vibration! That was a great tip!! Thank you, I hated that vibration.

Great tip!!! I used the 1/4" and it worked excellent.

I put the exact same deflector on my 2021 BS and it didn't help.

Same, vibration before and after without TOO much noticeable difference. and I have had mine on for almost 3 years. I think I'll try the fuel line too, as I've just been living with it.

I had a piece of 5/16" fuel line, couldn't get it to go into the rear hood seal without possibly damaging the seal, I bought 5' of 1/4" ID x 1/2" OD fuel line at the auto parts store and still had to put liquid soap on it, haven't had a chance to jump on the interstate yet, I'll let everyone know after I do.
