Which do I need? Fuel pressure or rail pressure gauge

Hey guys.

Would like to just get one gauge as am running out of space to put gauges.

Which is more important, rail or fuel pressure. If I just get the rail pressure, is that enough?

Thanks.

Igor.

Both, since you have a MP-8 the RP gauge is also important.

Yeah they are both essential, gotta have them....I don't really like the idea of the low pressure warning light because you don't know how low the pressure is. I like to know what my pump is doing at all times.

I am going to go with both gauges.

Then will go with Smarty. See where my pressure is, where my goals are going, and then go with pump.

Will probably go with AirDog 150, and do my own pickup tube with return and an all new line to CP3. Leave the stock stuff plumbed in there for backup.
