I have a holley 4150 list # 4776-2 it's 600 dp i put a kit in it when i put it back on and started the car fuel was coming out the tubes were the breather sits i believe they are fuel bowl vents but not sure. would this happing because the floats not set right?
It could be that or your needle and seats are stuck open or you have too much fuel pressure . I'm shure there will be other ideas too
I had this problem with one awhile back. Mine ended up being a bad float it had pin hole size hole in it took me forever to find it and made me use alot of colorful language in the process. Most likely there stuck or not adjusted properly but check to make sure there not taking on fuel as well.
