TH350 Vacuum Hose Keeps Popping Out

[Starwood]

The vacuum hose that goes from my Carb to my TH350 keeps popping out on the transmission module.

I did cut the tube about 1/2" hoping it'd get a little more snug, but every time I crank her over, it pops out.

Just checking to see if there are any tricks to keep this line on before I get in the "Replace it" lane. Silicone? Bigger Hammer, haha?

Thanks in advance for any replies.
