I was bleeding the ABS pump the other day and it wouldnt bleed for some reason. so i put pressure through the bleeder to blow whatever dirt out but it just plugged up again, so i rigged a hose onto my shopvac to try and make a homemade vacuum bleeder but that didnt work either. I was going to buy a vacuum pump but im broke so i figured there must be something around the barn i could use.I took the stopper out of a gas can and put a tire valve in it and siliconed it, and ended up with this handy tool that allowed me to blow the dirt out of the system and get it bled
