Just completed my procharger build, installed the fore hanger with triple 255's.
Used wire unions and heat shrink with all wires inside tank, clipped the leveler as it was supposed to be clipped into the hanger.
The sending unit worked properly for the first 30 miles. Then suddenly went to 0 and digital panel is saying Check full system.
So I'm not sure what could have came loose or maybe a fuse popped?
Is there any way to keep an idea of how much fuel is in my tank before having to drop it all out and see what's happened?
Iv filled the tank up and it didn't change anything also. I also went to the digital fuel range display and it shows " low range " .

If you clear the codes in the PCM the gauge most likely work again.

Clear codes. You can also see which sensor is not working using a tech 2. A wire could have come loose or it got stuck, or you get that same error if transfer pump isn't working.

Mine did the same thing I just cleared the code and my gas gauge started working again. I have a fore hangar.

Awesome. Clearing the code worked. Thanks a lot guys. Huge relief knowing I don't have to drop the tank .

Wait and see if it comes back. If there is an issue it will keep coming back. Clearing mine would help for ~150-200 miles until fuel system was all working properly.
