plus if ya have a drop in the gauge...You are going to feel the motor loose rpm before ya notice the gauge, unless you just stare at the fuel pressure all the time............Not knocking ya i just prefer the light system in a high performance application...

at w.o.t it should maintain 5 psi. if it drops below that its starting to run lean. leaner is meaner, but with catastrophic result.

if u went thru the trouble to wire and drill in the light, then y not a gauge.you may as well use just a light for the oil and temp as well.
lights are an alarm circuit to alert you when a malfunction is occuring. they are handy when running from a cruise to having it bricked. you must watch the water while runing hard, so having a light up high , thats in line of sight is great, but when you idle bnack down it would be nice to know just how bad is your problem.
i personally believe all boats should have full guages including fuel psi AND pyro. as well as audable and visual alrms.

What sensors do you use for fuel and oil pressure lights?

Didn't have the ground hooked up yet. Not good for the guage!

Ah Ha !!! So you do care ... I have no problem with the light setup .... its prob a great idea ... On my 311 I have limited dash area and have been pondering how could I ad more gauges .... also tied to the Audible alarm ?

i guess my point is u have to have something in a high perfortmance motor......(i prefere a light for fuel pressure....i also have warning lights for oil temp and oil pres..............How often due ya notice a gauge in your car climbing....not very often i bet but ya sure notice that pucking seat belt let dont ya ............

the oil pressure light kit is a longrace and the fuel pres light kit is from a nitrous works kit......your local machine shop should have books for both..........if not pm me and i can help.............god knows i have had a lot of help from others on here

yes i care a lot......... iwas not trying to piss ya off.......i just thought it was pointless for a stock guy to hawg a hole in his dash/............
