Ok, so i'm going to change my fuel filter, I know how to change it, but thats it. What other steps do I have to take?
Does the fuel system have to be de-pressurized? If so, how?
It's an 89 GMC sierra.
Thanks.Fuel filter?Ok heres the skinny on your little situation the fuel system needs to be depressureized its fairly simple find the fuse for your fuel pump and take it out now start your truck and let it turn over for about 15 or 20 seconds there you go seing that is an 89 if I recall you just need a set of wrenches just ask at the parts store where you get it and if you need a quick disconnect fitting tool you can get them at the same time for about 10 dollars now when you get under there and there is a quick disconnect there are 3 a blue and 2 white ones but the biggest one is for the a/c system it should be the blue one put it on the end of your old filter push it in and slide the fuel line off put it back together and your all setFuel filter?its been 3 years, but double check some chevys and gmc require a special tool to take it off, and put new one on. If you dont get any good answers I will phone a friend and find out for sure, he is a grease monkey. oh dont forget to prime when u are done. turn key to the on position 3 times, but dont crank it, should be able to hear the fuel pump and double check for leaks before you crank, and check again. other then that should be it, put a lil pan under it when u disconnect it, and dont have ur face right under it, lesson many learn the hard way. should get a lil fuel out but not a ton, and old filter will have some in it.Fuel filter?The only thing to do is make sure the keys are not in the ingnition, take the gas cap off, and spray the lines with some PB Blaster and let soak for a while to get rust off. No matter what you will have some pressure in the lines and gas will come out. The most important thing is when you are done and everything is back to normal make sure you prime the filter. Turn the key forward to the on position (Not starting), then turn off and then do it again. Then you may start the vehicle and watch for leaks. You want to prime the filter twice so you don't burn out the fuel pump. Other than that it should be fairly easy. Just have a 16mm and 20mm open end or line wrench handy and you should be all set.Fuel filter?Well, first you have to remove that damned #3 from the back window, or I am not going to help you with anything. I am cool with the Red Wings sticker, but that #3 sticker has to go, and I mean now!
