I think I noticed this when I first installed the fuel pump but definitely noticed it today. Silly me didn't get to fill up this morning so I went to work. Had less than a 1/4 of a tank. Was driving home and was pretty much right at E. I figured normally the check gage light comes on when there is about 2 gallons left. This used to happen all the time with my old fuel pump but when I replaced it a few months back with an OEM unit I didn't really notice it because I never really let it get this low ever... But sure enough even taking hills/turns with the low fuel it did not trigger the little red check gage light to come on?

When I filled up it took 15.999 gallons so I only had about .5 gallons in there if the tank is 16.5, which I believe my single cab xlt is.

When I start the truck the red check gage like come on then goes off like it always has. Bulb isn't burned out and everytime the truck is started that light comes on like the rest then shuts off.

What might cause this light to not come on when there is low fuel? If I remember there was one electrical connector to the entire new fuel assembly.

Gauge need goes up and down just as it should when fuel is being used/filled up so that part isn't an issue.

More curious than anything just because I don't like knowing stuff isn't working... even though this was a rare case in letting it run this low on fuel, I'm wondering what else factors in to let the truck know when to activate that light.

Thanks,
