Fuel problem!!
Guys I have a problem that is driving me nuts!! I changed the fuel filters on the truck and I think the truck may have gotten air in the system as I was told that wouldn't let the car start... How could I drain the system of Air. Please share your knowledge guys I desperately need your help!!!

Did you snap the filter into the cap and then screw it in? Did you use new o-rings? Did yoyu lubricate the o-rings w/ oil? Are you sure you are not cross threaded? Did you use a torque wrench on the caps or just tighten "by feel"?

Oil lubrictaion is always a good idea. It keeps the o-ring from getting dried out from the fuel and it helps it stay in place when the filter is installed (they can "kink" although it is rare).
The filter packaging includes instructions that have the torque specs. How necessary it is, I do not know for sure. However, I have heard of folks cracking the plastic cap from over tightening the cap.
Lots of folks have found it awkward to get their hand (and tools) on the HFCM filter cap. If it is not started correctly when screwing the cap on, the metal threads of the housing can be off set from the threads of the plastic cap. This can damage the cap threads when trying to tighten the cap down. The cap will then eventually leak.

I quit using a torque wrench on the fuel and oil caps, it would click before the cap was seated completely because the o-ring was too tight. I just tighten until the cap seats and give it a little more snug.
