I've used one with a plastic bottom and it held vacume but the solvents started eating holes in the bottom causing air bubbles... anybody experienced this?

Okay guys, I don't know what it is, but I can never seem to get a filtration unit to hold ANY pressure at all. I'm using a hand-brake kit I got from Advanced Auto, and I've been at it with multiple filters for about a month. I can never get it to register ANY suction at all. What gives? I don't understand what I'm not doing right, it seemed to be pretty plug and play?

what's the brand of the filter and size bottle your using?
