vacuum block

[jerritt]

i got the block from buickgn.com where you need to buy the brass fittings for the hoses. what size are the fittings i need? i know its a 1/8 NPT but what sizes for the lines. im using the fuel pressure, boost gauge, PCV, vacuum breaks, and one to the vacuum ball, and then im blocking the last hole. i know the PCV and breaks are 3/8 but finding a 1/8 NPT and 3/8 was tough so any ideas where to get these other then lowes because i didnt find much there. thanks for the help.

Try your nearest napa auto parts. Or if you have a industrial supplier that handles weather head or Parker fittings. Looks like 1/4 &3/16 to me. I'm use some silicon hose on mine it's 8mm for the fuel pressure.
