Air hose leak?/bad gas mileage

what is the code for the check engine light?if you don't know,then take it to Autozone and have them read the code/codes,then ask them to print the code/codes out for you,it's FREE!then post the code/codes here.air something?if you put $10.00 worth of gas in it and drove it 8 miles and the low fuel light came on,then it had to be on empty or close,when you put the gas in it!if you keep running it low on fuel,it's very likely that you will burn up that $300.00 fuel pump that's in the fuel tank.when the truck gets on 1/4 tank,consider that as empty,and go put more fuel in it.fuel pump must stay covered/submerged with fuel to keep the pump running cool.when it gets hot,it works harder,and will soon burn out,if you keep running it low on fuel.
