F150 FUEL PRESSURE LEAK DOWN OVERNIGHT

1991 Ford F-150

1991 Ford F150 V8 Four Wheel Drive Automatic

i have a 91 ford f150 4wd and I have a problem with the fuel pressure leaking down at night. It takes several minutes to get it cranked but runs fine afterwards. Seems worse when moisture in air is higher. I'm afraid it is going to burn my fuel pump out. Any help would be greatly appreciated

Your probable causes here could be the injector/s, fuel pressure regulator and fuel pump check valve leaking
