Does any one have a Greddy oil sandwich kit. I found one for about $35 cheaper than the Golden Eagle adn was wondering if there is anything bad about it?
Does it use NPT fittings or is it metric? I heard of it have different thread pitch and was difficult to find adapters for oil pressure sensors and oil line fittings...

otherwise, does anyone run a greddy oil pressure gauge with sensor? What size is the sensor and thread pitch? does it fit on the Greddy or GE sandwich???
