Yeah, then your milage will plummet to the floor. Youll be wondering why you're suddenly only gettin 6 mpg. Ive personally never had and problems with the fuel filter. I change it in about 4 minutes and i've even done it in my nice clothes once.

 

ill make you guys a deal! ill change your fule filter if you change my spark plugs.

Well I took a look at it with the key in the "on" positiopn and with the truck running as well, no fuel spilling or leaking. Is it possible the 03's or at least my truck anyway has a different fuel line? Do both lines that connect to the filter use the same type of safety clamp? Mine don't. The one in front uses the kind I have seen pictures of in other threads, the rear on has something totally different.

 

take a pic of the other clamp.. if it comes off by hand, i wouldn't think that it would be safe..
