[DESTRO]

Since the weather here has turned warm here in newengland I have had a few episodes of very high fuel pressure, 100 PSI, when typically it is just less than 70 PSI. This seems to occur randomly after the truck has been run and is restarted after a short while. Everything is still hot under the hood when this happens. If I start a couple hours after shutdown I don’t run into this problem. I have taken a look at engine codes with my Evolution and everything is good. For other mods I have a 4” exhaust, custom open element intake, boost and EGT gauges and of course a fuel pressure gauge. Any ideas on this one? /ubbthreads/images/graemlins/shrug.gif

I have this problem to some degree, but the pressure
only goes up to 75psi. When the weather changes like
during the winter months, I have to reset it. Chris Muncy
at DI tells me to leave it alone. But, I have play with
my toys so I adjust it back and forth. /ubbthreads/images/graemlins/warmsmile.gif
