i want to verify if my head gaskets are leaking so the first step is to check my cooling system to see if it's building pressure. i'm trying to build a pressure tester and i have the heater hose and fittings but i can't find a simple 30psi dial gauge. i have tried home depot, pep boys harbor freight and nothing. does anyone know where i can get a dial gauge to test the pressure in my cooling system?

 

Autozone sells a kit complete with 3/8" Tee ask for a fuel pressure gauge

I just made my own,,10' of 5/16 hose, ( 11'-12' might work better)a Tee, a 20-30 lb Gauge(if possible, mine was a 60lb) and some Clamps,,,left it hooked up for 3 days while I went to work,,,17lbs was my highest #!
