So i recently bought an aftermarket fuel pressure regulator from E-bay for a kind of budget build project. My question about the regulator is that to adjust it you have to turn a little flat head screw where the vaccum line usually connects. There is a tiny little hole going through the adjustment screw though. So should i just hook the vaccum line back into the adjustment screw after adjusting the pressure OR just cap off the vaccum line altogether. This is my first afetrmarket pressure regulator and they might all be like this, but like i said i have no prior knowledge in this field. To make matters worse i have no idea what brand the regulator is. Any advice would be great. Thank you for taking the time to help me out of my little dilema.
 
mine was like that but it was not from ebay.

mine was like that but it was not from ebay. the way i was told to do it is pull the vac line off and put your finger over the hole in the vac line. then adjust your fuel pressure to where u want it then but the vac line back on
