    Question about pluggin the hole in upper intake manifold...

    ...just like it sounds. Because it's late and I don't want to measure it (shame on me) what size plug should I order to plug the rear opening in the upper intake manny for where the brake booster or whatever the shiz that is? I'm about to do the clutch booster delete (that's where one of my boost leaks are) and just want to know the plug i need to order so that I can knock it out quick status.

    I am going to snag a 1/8" bspt plug as well as a temp sensor adapter for my water temp gauge to toss it in the coolant line but would love to knock this out at the same time.

    Thanks in advance, guys, and if this doesn't make enough sense I will clarify it tomorrow when I'm fresh and sober.

    I did a cluth boost delete, but tied the clutch booster into the brake booster, both of which need a vacuum source. There is also a check valve you'll need to re-use so you don't supply boost.

    I can take pics later, car is not available at the moment.....

    Here's how I did mine....IMAG0032.jpg

    Nothing fancy here, but it gets the job done. Just need one 90 degree fitting, one tee fitting and a short section of hose. Make sure you put the check valve in the line, I reused one of the factory ones. Kinda hard to see in pic, but by the IC pipe runs to the mani, check falve before the tee fitting, rest is easy.
