Hi

I’ve got an inverted OS 46 in a Nobler. Does it make any difference if the Needle is on the outside or inside ot the circle ( as in which way round the spray bar is inserted)? I’m guessing not as the holes in the spraybar stay in the same position in the venturi so any pressure differential to the tank will be the same right?

Cheers

I don't think it makes any difference. Just keep the fuel tubing from the tank to the NVA efficiently routed and as short as you can.

I have a 40LA on a Nobler with the NVA inside. Then a 46LA on a Vector with the NVA outside. I don't notice any difference in the engine runs.

And in both instances the NVA's are front type, not the rear needle setup.
