Just bought 3 new FOne strikes and they recommend 8 and 9 PSI but my Duotone pump only has 7 marked. Do I just pump up the wings into the middle of the red zone for 8 and to the end of the red zone for 9?
Pity the pump doesn't go up to "11" ??
Yeah I'd go to the end of the red. Most wings should have some margin of error built in. The reedin wings I ride last fine at 9-10 PSI even though they're rated for 8. They start to blow up at 11. My guess would be slightly over pumping the wing will make it ride better but decrease the lifespan a little.
Just be careful if you're loading the wing hard in windy, gusty conditions. The times I have blown wings have been racing or loading for jumps in 25-30 gusty wind while over pumped.

You could buy a Naish pump.. 
Can you just buy the gauges separately? They just screw in and out and seem pretty standard in their size and thread. I have the same issue with my Duotone pump. The gauge is perfect for Echo's and the original Slicks, but the newer SLS Slicks require a higher psi, (particularly the smaller sizes)
Re buying gauges separately I'm not sure about Naish but if you look on line you will see some..
I'd try your local shop first..
My local, Briskites, had spare Naish gauges so worthwhile asked at your local Naish dealer.
New Duotone pump gauges go higher, I think to around 11psi. Not sure when they changed. I guess because older wings ran lower pressure.
