How important is a fuel pressure gauge?

I'll probably be getting gauges in a couple of weeks and I was wondering the importance of a fuel pressure gauge. Because I already have an AirDog, I was thinking if I need a fuel pressure gauge, I should get a dual readout digital one. My delima is these are pricey and it will delay me getting gauges for a little bit.

I never plan on having a big turbo, wild tunes, big oil, injectors... In fact when I order either the DP or PHP I probably won't get any tune stronger than 80. Basically it'll stay close to stock with a tuner.

Thanks,

Jason

I probably should have said I'm definitly getting an EGT, Boost, & Tranny Temp gauge but how important is a fuel pressure gauge for a slightly modified/ stock truck? If I never get one, will it hurt anything?

It will only hurt because you wont be able to read your FP, and/or recognize developing problems immediately. Yes, its better to have. No, you dont NEED one in the respect stated above. Even mildly modded trucks NEED the other three, IMHO.

fuel pressure is important. If you run with not enough for long enough you can hurt the injectors. Also gives you an idea when the filter needs to be changed because you will see the gauge fall more then normal when you take off.
