Depressurizing - 2/28/2008 4:31:14 AM    modem7890   Posts: 19 Joined: 10/8/2005 Status: offline I'm replacing my fuel filter, hopefully this weekend, and I was reading up on depressurizing the fuel system.  My question is, can I just full the fuel pump fuse under the hood and crank the vehicle to depressurize instead of finding and pulling the relay?  Isn't pulling the fuse the same as pulling the relay?

Just keep the key off and take the gas cap off, you will have gas leak about 8 to 16 oz's have a rag to keep the spray in one place and you will be ok. _____________________________ I do not need the National Geographic channel I just look out the windows of my Land Rover Discovery code name Romulus Prefix-N or 1996 Classic Discovery, RPi remapped ECU NRP Preformance cats/Y-pipe (in reply to modem7890) Post #: 2

Don't forget to use lots of penetrating oil a day ahead of time so you can loosen the fuel filter fittings. _____________________________ Mike Retired service manager.

Also, thanks for the tip on penetrating oil, it's been a long time since this filter has been changed. Thanks again. _____________________________ 98 Discovery (in reply to modem7890) Post #: 4

RE: Depressurizing - 2/28/2008 7:52:14 AM    modem7890   Posts: 19 Joined: 10/8/2005 Status: offline I've replaced the plugs and wires (Magnacore's 8mm), engine flush (added synthetic oil), coolant flush, replaced the transmission fluid and serpentine belt.  My Discovery just rolled over to 100K. I love this vehicle and I want to keep it going for as long as possible.  Recently, in the cold weather, it's been a little hard starting.  I went away for a week and nearly drained the battery trying to get it started on a 19 degree morning.  I'm changing the fuel filter this weekend and brought a set of Ford yellow tops to replace the Lucas injectors.  It may be overkill, but I plan to keep replacing critical parts before they fail.  Cats, O2 sensors and water pump next.  A fool and his money? _____________________________ 98 Discovery (in reply to modem7890) Post #: 6

They are a lot cheaper than replacing the whole Y and give you a little better flow. I haven't noticed any power/MPG gains, but it is a little throatier in the exhaust... _____________________________ 97 Discovery SD-7 156K miles 04 Cadillac CTS 34K miles Good Oil number of posts does not = knowledge (unless it is me) (in reply to modem7890) Post #: 7
