Default fuel mileage

First of all, I know there are alot of threads bout mileage but my truck has to have some problem. Well I filled it up most of the way the other day and I have bout 216 miles on it so far and its lil below half a tank. Usually my truck dies after it gets a lil lower. I usually get like 350 miles before that happens but sometimes it dies. It seems like I'm gettin more miles before it that happens. Could it be something with my float in my tank, idk, its been doin this for several months and havent gotten around to checking that out

When it dies how much fuel does it take to fill it up? Have you checked the lift pump to make sure it is working properly?

I'm thinking you may have some junk in your tank which could be clogging your fuel pickupand or a clogged fuel filter.

IF there was no change in the problem after you changed the fuel filter the next thing I would do is check the tank out.

Do you think the float could be stuck on something and need to be reset cause I hope I dont need to replace the whole thing

Yeah, I'm thinking that you may have something clogging the intake in your tank. You may hafta drop the tank and clean it out. Not sure, but you MAY have a sock type filter inside of your fuel tank that may need to be replaced.

Also I think I used to get like 450 miles to a tank of fuel thats why I kinda think it's not picking up fuel when it gets so far. I also posted awhile back bout thhis problem caus I ha started it up with starter fuild before when it died and it had white smoke. Now I know or an easiser and safer way to start it now

I don't think it would be your sending unit (float). It' sonly taking 22 -25 gallons to fill up so your not actually out of fuel. I think your tank is bigger than that. I would either drop the tank and have a look or find someone with a scope that will go down the fill pipe and let you see inside the tank.
