I know this has come up a number of times. I get low fuel pressure in a steep climb like many RVs. I have an O-360 A1A carbed engine, factory new from vans. I never paid much attention to the low fuel pressure. I have 380 hours on my 6 and it has never missed a beat. On climb out from take off I always have my electric boost pump on and pressure is 4 or 5 pounds. The few times I took off forgeting the boost pump I still have a pound or two and like I said it's never missed a beat. The other day I was fooling around doing a little mild aerobatics. I was in a steep climb and my girl on the dynon skyview came on and said "fuel pressure". I get it a lot, when fooling around in a steep climb. I've seen zero pressure. I hit the boost pump and I heard "fuel flow". I did think anything of it. Then later on a different flight it did the same thing fuel pressure" then after hitting the boost pump I got "fuel flow" I looked down at the screen and saw my fuel flow at 18 or 19 GPH in the red. It never goes above 15 on full power climb outs. Again I didn't think anything of it, But after thinking about it later, I think I know what is happening. The fuel level in the bowl is getting low, and when I hit the boost pump it refilled the bowl with extra high flow rates which prompted the "fuel flow". Something to think about. I don't know how long I would have to climb that steep for it to die but I think it would if I kept going. At the least I'm getting a lean mixture to the engine under full power which is not a good thing. So doing aerobatics from now on gets the boost pump on.
