You can order the tap from : www.aquamist-direct.com

If you have room, it is better to order a 1/8NPT jet adaptor. The 1/8NPT is quite common in the US, so save yourself a few dollars by not ordering the M8 x 0.75mm tap (quite expensive)

Thanks Richard - I am actually trying to add a port on the other side, away from the injector/nozzle. I do have a 1/8 NPT adapter for the position at the turbo but since I have a 6 cyl car, 6 port direct injection manifold, and adding a 7th injector at the turbo, I need to add an additional outlet on the manifold. Here is the part I need to attach:

4mm to M5 compression fitting. Just not sure if its M5 x 0.8 or M5 x 0.5
