Just Installed Edge Fuel Pressure Gauge. Doesn't look to great...

[baycountry16]

Just installed my edge fuel pressure gauge and I'm sitting at 49 psi at idle. drove truck a little bit and it drops to about 45 at half throttle. Luckily in the three months I've had truck, I've driven very little on the highway and haven't really opened it up yet. I too am scared to run it at WOT now with the psi only at 49 at idle. who knows what pressure will drop to. who knows how long its been like that and how previous owner drove it. hopefully the injectors aren't messed up. Truck seems to run fine.

I'll be getting blue spring soon, but probably won't have time to install till next week. need truck to go to work and don't really have a choice. few questions though:

1. Think I'll be okay driving it as long as I keep off the pedal too hard for the next few days?

2.Also, anyone have any tips for getting the CAC tube off and out of the way when I do this install? I've heard it is a pain in the azz to get off.

3. My MPG"S have sucked and been absolutely awful since buying truck. Could low fuel PSI cause poor MPG's?

4. Havent checked fuel filters since purchasing truck as well. Could clogged fuel filters cause low psi as well and/or poor mpgs's?

The mods just never seem to end with this thing, but I'm having fun doing them!!!

Thanks for any info as always!

I don't think it will help the low mpg must be something different but the low pressure will kill the injectors i had the same pressure also this may help some of the pics don't load for some reason but it will help.
Here you go this is a good post by Band_ Member on the fuel pressure reg spring install. Just remember 99% of the 6.0 running around have low fuel pressure and don't know it.

Changing filters at regular intervals is just good preventative maintenance.

As far as the fuel pressure goes; I believe that the lower limit is 45 psi, although mine is higher with the "blue spring" kit.

Thanks for the tips, and thats a great point 2 stroker about most trucks running low fuel pressure and not even knowing it. I guess I won't sweat it too much until I get the blue spring kit and get it put on early next week. I'll just take her easy! I can't wait to get it put in though. most everyone on here has said they've seen a pretty noticeable improvement once upgrade was done.
