Injector O-Rings?

OK, simple question. How do you know when it's time to change the o-rings on your injectors?

A good indication is to look at ur fuel filter if it is black then its time

Nope, I just changed the fuel filter and it looked OK. The reason I ask is because I have an early 99 F250 4x4 with a six speed with 4.11 gears that is getting 10MPG towing a 5K trailer at 65, That seems low to me. Other then that t he truck runs great. I used an Edge on Tow safe to get that milage, tires a properly inflated, have plenty of boost when needed but I keep the RPMs below 2K. Am I missing somthing or is this realy good mileage? Thanks

That fuel mileage isnt really that bad... considering what terrain your towing on.

I was towing on Flat land on I5 in the Northern CA valley. I guess I was hopping for more.
