1/16th NPT -3AN 1/8th poly line ferrule nuts

A great deal of time has been spent hunting around the internet for fittings and hoses for the Nitrous kit. Because i have two different brands of nitrous parts it's causing some problems, that and the fact that all the parts are obsolete non metric fittings.
The Nitrous nozzles/foggers are made by Nitrous Express and the rest of the kit is made by NOS.
Because of the expense of braided lines to connect foggers to the solenoids i want to use 1/8 th plastic (poly) line. But you cant use poly line on the Nitrous express foggers unless you buy a conversion kit..... a kit i can't get hold of anywhere!
Anyway ... as it turns out, Roger Upperton has told me what nobody else would, in that if you drill the fogger inlets slightly they will loosely accept NOS funnel jets, which should work ok.
It is insane trying to make sense of the thread sizes though. What relevance the thread size 1/16 NPT has to 1/16 of an inch i do not know.

The advantage of the Piranha nozzles is their symmetrical shape. I have been able to drill, tap and thread them into the inlets without the usual performance of machining away the cooling fins and having the cylinder head off to do it.
The fogger requires 1/16th NPT thread, so a 6mm drill bit is correct to then use a 1/16th NPT tap on. You need only send the tap in half way as it is tapered.

Other tasks underway at the moment ....
I have a Lambda boss waiting to be welded onto the exhaust. I can't weld it on as it's too thin for arc welding, so i will ask my mate if he can do it for me. The boss will allow the use of a wideband O2 sensor to get accurate Air/Fuel mixture readings.
I've abandoned the idea of going to the dyno with a selection of jets. Instead i've bought a pack of tiny drill bits (0.3mm -3.2mm) and some pin drills, then i'll simply drill the jets out until the right size is obtained. If i go too big then they can be soldered back up and drilled out with the correct size.
The fork brace is nearly complete and looks a whole heap better than it did. I've also decided it looks better upside down!

I need to test the carbs can cope with being fed fuel from the fuel pump without flooding. They were gravity fed but to make the fuel system simpler i need to connect them and the fuel solenoid to the pump. Also the ACU rulebook says the fuel shutoff should be within easy reach so the pump will allow me to place the fuel tap in an accessible place without having to think about upsetting the gravity feed.

Finally i've managed to get hold of some DZUS type fasteners for the bodywork. I bought a small selection to make sure the sizes are correct as they cost a fortune. Luckily they are all the right length, so i can order some more. It also turns out there is more than one company making this type of fastener, the place that makes these is DFCI
