metroplex said:Awesome tip about the tool! I've never heard of those type of pliers, but I ordered the OTC version. Are the vacuum caps about 1" or less in diameter? I recall my notes saying 15/16" would work better but that was in February when I was recovering from major surgery and it was bitterly cold outside.
I had never heard of that tool either, but got the tip either here or explorerforums. I wish I could remember the original tipper, so I could give him credit. But yeah, totally worth it for that back clamp. I actually elected to re-use the spring clamp on my rear BOV port (I used it for an OCC vacuum source). You can lock the spring clamp open with the tool and re-install using the same process in reverse.

I used a cap for mine for 1" OD tube. Looking at derdog's caps, he is also using 1 to 1-1/16" OD caps. You might be able to squeeze on a 15/16" cap if you can find one. Count on using a hose clamp regardless to seal it up.
Good luck!
