plate system fuel T ideas / pics please

[fastaarcuda]

I'm doing a simple NOS Powershot plate system with a Holley 4150 750 double pumper dual line carb. I am looking for suggestions and pics of your setups, just looking for a fairly simple way to Tee off of my fuel line to the fuel solenoid. I need to be able to somehow Tee off of a fuel pressure regulator or off of the fuel line itself. Also any pics of how you mounted your microswitch at the carb.
Thanks in advance.

You have to get it smoke tested. Other possible causes include the valves (purge svalve, tank bypass valve) the lines going from the engine bay back to the tank, the tank itself, fuel pump plate, filler neck, etc. There's a lot of potential leaks in the system that can be near impossible to find without a smoke machine

For a simple Powershot plate setup on a Holley 4150 750 DP, the cleanest way to handle fuel is to avoid “random T fittings” off the main line if possible.

Best practice is running a dedicated feed from the regulator to the nitrous fuel solenoid. If your regulator has an extra outlet, use that. If not, a proper AN Y-block or distribution block is much safer than a hardware-store T, because it keeps pressure stable when both carb and nitrous demand fuel.

Try to keep the line to the solenoid as short and straight as possible, and avoid stacking multiple fittings right before it.

For the microswitch, most people mount it on a small fabricated L-bracket on the carb throttle stud or secondary linkage bracket. You want it to trigger exactly at full throttle, with a solid “click” right at WOT but not early. Some setups use the rear carb stud so it stays rigid and doesn’t flex under load.

The key with a simple nitrous setup is stability: clean fuel supply, stable pressure, and a very reliable WOT trigger.
