I'm replacing my fuel filter, hopefully this weekend, and I wasreading 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?

 

No fuel filter on a Disco II,,,,, so you have a Disco I?

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.

 

That is the easiest way, although you may throw a code and need to clear it afterwards.
Don't forget to use lots of penetrating oil a day ahead of time so you can loosen the fuel filter fittings.

 

Thanks for the input. I think I will go with the pulling of the fuse and have the code cleared later. I have to take it to the shop to have new fuel injectors put in and I'll have the codes read and cleared then. I also need to have the codes read due to an earlier post on an acceleration noise I have and Mike asked what codes were reported, so two birds with one stone.

Also, thanks for the tip on penetrating oil, it's been a long time since this filter has been changed.

Thanks again.

 

Why are you replacing the injectors?

 

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 Discoveryjust 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 itstarted on a 19 degree morning.I'm changing the fuel filter thisweekend 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?

 

When you get to the cats, check out the high flow cats from Magnaflow. 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...
