how are you guys connecting the purple/pink vac hose to a vac block? do you know what size id that is? or wth i can use to attach to my vac block? i have a holley block i believe the threaded areas are 1/8 npt and 1/4 .i can figure that out just not sure what to use to connect to that actual small vac line.

i used a piece of shrink tube to in act as a sleeve to fit(accordingly) into a small section of rubber hose.this pic isn't of it going into the block but it paints a picture,hopefully it'll help. i don't know what size hose that is,it was just what i came across in my travels. 20240821_202743.jpg

ok so you were able to basically splice them using some shrink wrap? i ordered a 1/8 barb and pushlok fitting. hopefully it works. if it fits ill put some shrink wrap on it. thanks
