Gauge fittings?

[TRAMPLINEMAN]

What does everybody use or recommend for fitting size? 1/8 or 1/4? What is the benefit/downfall to both?

All my Isspro gauges were 1/8" native. They all came with an adapter to adapt to 1/4". I don't think you want to drill a 1/4" hole in the exhaust manifold though. Too big of a hole! Also both the Fuel Pressure fitting on the GDP filter was 1/8" and the boost bolt is too.

Bottom line, no reason to go to 1/4!

Go juice with attitude and you don't have to worry about it, it comes with everything you need!
