What kind of fitting in exhaust manifold for drive pressure?

12' is way overkill. Like rob said, 2' will be just fine.

It's 12' total from the fitting to the gauge. Even without the coil the run would be about 8 ft, so figure there's probably 4 ft in the coil itself. The line is copper the whole way.

the 1/8" copper plugs up super fast, never had luck with it, had to switch to 1/4 copper and then the 1/8 nylon worked fine from the filter to the gauge.

I had the same problem. And after about 6 months my mechanical gauge sooted up. This is my setup now with a JGS filter:

Thanks for the pic and everyone's info, looks like I'll be redoing mine.

I've got the same set up as Dustin, great filter and easy to clean.

Where did you guys get the filter?

Nevermind I found it on JGS website.

Ordered the filter today. Also found a 1/8 NPT x 1/4 OD brass compression fitting on Amazon so I don't have to pull and redrill/tap the manifold for a larger size, that was nice. Got 5' of 1/4" copper tubing on the way too. Thanks for the help everyone.
