change fuel filter in 91 Accord DIY project or not?dderolph 08-16-2006, 03:24 PM Is this a DIY (Do It Yourself) project or not? If it is, what's the safe way to relieve pressure on the fuel line? Any special tools required? jeffcoslacker 08-16-2006, 04:28 PM Is this a DIY (Do It Yourself) project or not? If it is, what's the safe way to relieve pressure on the fuel line? Any special tools required? If I remember right, it's just a couple of banjo bolts on either end...if you can see it, and have room to swing a wrench, and have a wrench that'll fit it good, without buggering up the bolts, then I'd say you're set...otherwise, nothing but aggravation. I'm retarded, I never relieve the fuel pressure...it sprays out for about a second when you first crack the first fitting, then that's it...if you are real worried about it, pull the fuel pump fuse or fuel pump relay harness and start the car, it'll run a second or two and die...that'll take the pressure off. Or you can put a rag around the service port (looks like a tire stem) on the fuel rail, and depress the Schreader valve...the fuel will blow out into the rag momentarily, then you're set... jeffcoslacker 08-16-2006, 04:30 PM PS...I've seen folks get partway through the job, then decide they'd like some music and turn the ignition on so they can listen to the radio, energizing the fuel pump again...don't be one of those...it's always distressing (and yet oddly humorous) to watch... vtownx 08-16-2006, 05:56 PM definately a DIY, not what i can say about my 94 however. I used to own a 90 accord, and it was pretty straight forward. As you probably know its against the firewall, near the fuse box. There should be a box right above it, and you can just remove the bolts on it and move it out of the way. You will have to remove the bolts on the fuel filter, and then relieve the fuel pressure. A good way that ive been told and use, is just pop the fuel door, and then take the fuel cap off the fuel tank, and that should relieve the pressure. Undo the banjo bolts on the fuel filter, and make sure you unscrew them with a rag in hand. Installation is reversal of removal. Its pretty easy and straight foward, not too complicated, and definately DIY. hondacivic99sivtec 08-17-2006, 01:38 AM a decent DIY. it's really straight forward job. jeffcoslacker 08-17-2006, 07:58 AM A good way that ive been told and use, is just pop the fuel door, and then take the fuel cap off the fuel tank, and that should relieve the pressure. . Uhh...no. Talking about fuel system pressure, not residual pressure in the tank...nothing to do with each other. When you shut an injected engine down, the pressure in the line and injector rail is trapped by check valves. That way, you don't have to crank the engine until the fuel rail pressurizes every time you start it...that's why you were still spraying fuel and needing a rag when you loosened the fittings... Removing the fuel cap does nothing to relieve this, the pressure is held between the injectors and the pump... vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
