I have a 2003 duramax that I bought new. Got started on changing fuel filter for the first time [dealer did it in the past]. I have taken out the battery and inner fender panel so that every thing is very accesable. My problem is trying to unhook the electrical connector. I had read on this forum I think that you have to squeeze it to remove I have not had any luck and am afraid I will break it if I pull to hard. What am I missing on this. Thanks.

You shouldn't have to take out the battery or the inner fender, you can just pull it up out of there once its loose...

When changing the fuel filter, there should be a little button to push in and then you would simply just pull it apart. I had to mess around with it for my first time too so don't feel bad. I also just take out the battery and do it from the top. For me, it's and simplest. proven to be the fastest

I took out the fender, it makes it easier and only takes 5 mins. Dont sweat the plug man, just shine some light on it and you will see how it works, its the easiest part of the whole thing.
It would be nice if GM would have made the wire on each end of the plug 6" longer or placed the connection near the top of the filter head. I have been tempted to make two pig tails 6" long to get the connection up where it is easier to unhook. On the 06 the air tube is in the way enough that I remove it to see what I'm doing. The pros on here seam to have a easy time changing the fuel filter I think it is in a poor location and a pain to change.
Thanks for your replies to getting the wif line disconnected. Got it done today. had to get a magnifing glass from the house, then it all came together. I guess between the bifoculs and the 60 year old eyes I can't see as good as I used to. Anyway the job is done and everything else went like clockwork.Thanks again.
