Sometimes you really don't need to spend $80-100 for a gadget when you just might have the parts laying about your garage. Here's how I made, and use a homemade pressure tester with a small inline pressure gauge and a Mityvac brake bleeder kit.

Wear your safety glasses, or you'll put your eye out. Try on some gloves. Take off that spark plug boot. Clean your room. Open the windows, those fumes are nasty. Just 'cause I do it, don't think it's the end all, be all solution. There's plenty more ideas out there, I can't take responsibility if you slice off a few fingers after watching my videos. And don't just pour that toxic stuff down the sewer or in the ditch, dispose of waste responsibly. Just be safe, OK?
