I've seen holley DP's tapped with copper tubing from primary to secondary bowls to equalize fore/aft. but must be something simple, maybe the demon doesnt require float height in the middle of the sight glass I would check the manual.
It wants to stall upon fast braking and on downhill slopes...

It has nothing to do with equalizing anything.... It has to do with raising the height of the bowl vents so fuel doesn't slosh out..
While these Barry Grant carburetors are similar to the Holley models, there are some differences.
To connect the two vents would require some type of small diameter hard line to be pressed into the vent "stands" that these have.

Was looking at that in the previous pic of the way the vents are made....looks like a slight taper. If you have dial calipers you can measure the ID petty easily and go from there and can possible slip some tubing into them.
That would be easy enough but as others have mentioned the baffles or whistles would likely solve it too

If he has any small tubing laying around that fits and a tubing bender, it's a no money spent deal to find out....or lower the fuel level a bit....another no money spent try. If the tube is bent right it wouldn't need to be epoxied in. Grind a slot at the top of the curve, debur it, blow it out and done plus wouldn't have to pay who knows what on shipping or wait for them a month.
I've been fiddling with stuff on the car today. Moments ago I finally looked at the front and rear sight glasses in the carburetor.
These have horizontal grooves at the middle to help gauge fuel level. The front was above the line by about 3/16" and the rear was at the top of the sight glass. Chances are, it IS sloshing up and out on hard braking. I'll lower the float level and see how that changes things.
Here we go.....
It's a year and half later - did you solve this hard braking engine stall issue from fuel slosh? I had the same thing happen with my Quick Fuel carb and improved it by lowering the fuel level in the sight glass. It still happens sometimes on mine now that my brakes are better. I like the vent whistle thing posted above and may try that.
Yes. No stalling.
If I could keep a decent ECM from failing that would be nice.
I had another one crap out yesterday.
