Command Pro 23.5 CH730 Fuel Pump bypass question

[Sky3585]

I have a ch730 with mechanical fuel pump and have had issues with it. I was thinking of bypassing with a vacuum pump. I can’t find a port on block to get vacuum. I’m assuming if I pull from breather tube I’d build too much pressure in motor. What If I added a T to it? or am i missing the port somewhere i can tap into? Any one with experience with this?

Make a plate to fit over where the mechanical pump fits and thread a nipple into the plate for the vacum line. That's how I did one.
