Can't see how it would pop off it has vacuum all the time unless you hammer the throttle??, maybe it's a fit issue with the steel line??, I'd fire it up and go under and see what's going on???.

The vaccum comes from the intake right?

Yep, if it's factory there's a steel tube with a short stubby hose to a fitting on the intake behind the carb, it goes down to the modulator, usually it's clipped on the dipstick tube.

No, it would have to be the other way around to blow the hose off, vacuum is sucking from the intake not the modulator, if anything it'll pull the hose in.
