really bad mpg`s

I have a stock `95 f-250 225,000 miles on it . My truck has the dual tanks. I used to get about 245 miles off of one tank. Now its lucky to get 180 miles out of the same tank. I had poor mileage before because of the water in fuel sensor leaking. I fixed that and the mileage went back to where it should be. There is no fuel leaking anywhere now which cancels that problem out. Also when i tow our small travel trailer, fuel mileage is cut in half and it smokes a lot. Any suggestions? injectors maybe? I Hope not! Thanks for any help you guys can offer.

mods to the truck? that would help diagnose alot also possibly a bad turbo if it smokes alot without a chip. leaking up pipes could also be a culprit if they are really bad.

Do you have a catylytic converter stil on that thing? take a look under if you do and i bet you its pluggedd up. If you had gauges i'd say check your EGT's. Thats just a guess.

It doesn`t have any mods. It doesn`t have a cat anymore. unless its really big. The only thing under there is what looks like a muffler to me.The previous owner changed the exhaust out before i got it. What do the factory cats look like? I`ve had the truck for about 5 or 6 years. No major problems.

If the boot between the air filter and turbo is torn and you drive in dusty conditions, it is possible you dusted the turbo. If it's one of the smaller boots between the turbo and the heads you are losing boost and truck will be down on power. The large orange one is no longer available from ford, but the replacement one is black and comes in a "kit" from Ford and comes with a new boot, bracket, and CCV plastic piece.
