Fuel filter and PCV

Hi,
I am planning to replace the fuel filter and PCV valve on my car. I have 93 Maximan SOHC. I have two questions,
1). Where is the fuel pump fuse? I tried to find out it under the hood but could not find. Could someone please help to find it in my car?
2). How do I replace the PCV valve. I can locate it. To take it out, I tried to first remove the crimper on the hose connected to PCV valve. Even after 15 minutes, I could not take it off. Am I supposed to remove that crimper at all? Or just take out the valve from the engine block. Please help.

Thanks

For the fuse check the fuse pannel by the steering wheel.

Fuel Filter: I just did a tune-up to my car. The fuse for the fuel pump is under the side mirror controls. There is a handle pull it and then you see all the fuses. The fuel pump fuse is located on the right side, it's the first fuse one on the top, make sure. It's should be blue, a 15 amp fuse. The cover shows the location. Once you pull it out start the car and let it die. Go to the engine bay and locate the fuel filter located next to the brake booster the big black round thing behind the brake fluid resevoir. To the left is the fuel filter if you have a new you shouldn't have a problem locating it. Loosen the bottom and top clamps that hold the gas lines that go into the filter move them away from the filter. Just trying to pull these things away from each other might give some problems. I used a channel lock and a pulled and I had no problem.

PCV: I have a 1992 DOHC engine and it's said to change the PCV valve on my engine is very hard, took me 10 minutes. There is a hose that goes into the pcv valve that has a 90 degree angle to it so it makes it hard to move clamp so what I did was hold the clamp open and pull the hose and I came off easily. Get a 3/4 long socket and a pretty long extension and put it on top the pcv and loosen until it comes out. Now putting in the new pcv in a DOHC engine is a little tricky you need to use a spark plug tool the one that is bigger than the one we use actually for our spark plugs, I forgot the size. Put it in there so it won't drop out and put it in start tightening it just little once it went in a little, take out the spark plug tool and use the regular 3/4 socket and tighten until it get snug and that's it. To put back the hose hold the clamp open and put the hose in and release the clamp and that's it. The location of your pcv I don't know but the method of removing it must be the same.

Good Luck

Thanks guys for the information.

What did you use to keep the clamp open while you pulled off the hose for PCV replacement?

Why do you have to pull the fuse? So you make less of a mess with the gas?

yup, remove the fuel pump fuse, start the car and let it die (it'll run out of gas pretty quickly)
then try to start it a couple more times to get the gas out of the lines

then you wont have much fuel left in the filter and the fuel lines under the hood


for a list of all fuses and what they control, check my page in the how-to section

yes...by removing it and starting the car and letting it die, you depressurize the fuel lines

If I'm not mistaken, it's to release fuel pressure. Also, when doing the fuel filter, put new hose clamps on there. There are special fuel line clamps so use those.

Don't really want to steal the thread but my car broke down on me a couple weeks ago and I put a new filter on it. When I reomved the lines, there was gas there but it wasn't under pressure. The pump works b/c while I have the line off I turned the ingition on and fuel came out. So could it be the fpr thats gone bad?

Thanks

Thanks to all of you for useful information.

Finally, I did replace my fuel filter and PCV valve yesterday. Replacing PCV valve was not too bad but removing the hoses off the
old fuel filter was a pain. I did remove the fuel pump fuse and cranked the car a couple of times to release the pressure. It was easier to remove the bottom hose. It took around 15 minutes to remove the upper hose with the help of flat srew driver.

One question: In the process of removing the PCV valve, I loosened the clamp on the hose to PCV a little extra. Now the clamp on the hose is not that tight. Do I need to make it snug or its ok to leave it?

Where is the PCV valve located on the VE? I'm gonna do it and the fuel filter tomorrow.
