I'm moderately proficient at g-code, but I primarily use the CAM module associated with my CAD tool to generate the code, it's parametric so the code updates as I change the model. I very rarely code directly.Do you have any an spot facers and cut straight thread then you can use a 815 an part and much less chance of buggering as no tapered threads just o ring seal on the aluminum part.
Are you profecient at g code?
I can certainly do spot faces and straight threads, the problem is there is only one port that would benefit on this filter housing. Just about everything on the truck is female NPT. All the ports on the booster pump, etc. In a couple places it's converted to AN or something else, but most often it's direct to DOT tubing, which is a pipe thread interface.
On this fuel filter bracket, there are 6 ports and 3 plugs (not counting the filter interfaces), 5 of the ports must be NPT (direct to DOT tube or pressure gauge), one port is AN, but if I'm doing that much NPT already, one more isn't a big deal. On the plugs, 2 are pipe, one is o-ring-straight thread. The two pipe threads need to be recessed below the surface, which is easy with NPT, and I'm already using that size pipe 4 other places...
If I could reasonably get rid of all NPT everywhere, I certainly would, but it's all over the vehicle already, and for better or worse, it's the standard interface on so many needed parts like DOT tube fittings and pressure gauges. A necessary evil.
