Hi,

I have another dumb question: looking through my FSM, I see in the overall description section a reference to the fuel filter (which is what I'm looking for). I don't see any reference to that later on, but I do see a reference to the "fuel pump filter" in the section on removing the fuel pump. Are these the same thing?

Thanks,
Jason

 

The "fuel pump filter" is probably the intake net that goes on the pump's intakle inside the tank. This is different from the "fuel filter" which is outside the tank, on the fuel line going to the engine.

 

Any idea which section in this online FSM I can find the fuel filter replacement instructions?

Sorry for the noob questions... they'll get more intelligent as I go along.

 

Well, replacing the fuel filter is pretty easy, but I can see how it might be hard to find if you don't know what you're looking for. I would try in any of the "fuel" sections and see what you can find. I'll look real fast and see if I can find it.

But, what kind of engine do you have- 22RE (I-4) or 3VZ-E (V-6)?

 

I have the 3VZ-E.

Yeah, I'm sure it's a simple task, but my knowledge is pretty spotty... I didn't know much about engines until a couple of months ago when I began my head gasket replacement job. I obviously have gotten VERY familiar with my engine by this point, but some systems I haven't touched at all.

I'm getting pretty close to being finished, but I read in another thread that the fuel filter would be easier to replace while I have a lot of stuff out of the way still. I'm already replacing a bunch of things, so I figure I'll add that to the list.

 

Yeah, ironically enough I can't find the fuel filter instructions (perhaps it doesn't have any?)

If your 4Runner is similar to my '92 in terms of fuel delivery (should be) the filter should be on the fuel line next to your framerail (trace the fuel line from your tank to your engine to find it), its just a metal cylinder that has fuel line connections on each end. If you get a replacement you'll know what you're looking for. All you need to do is unbolt it from the line (make sure to use line wrenches so you don't round off the corners) and replace it. Since your engine has been down for a while, you won't have to worry about depressurizing the system or anything.

On a side note, the "fuel pump filter" is indeed the net that covers the intake on the fuel pump, not the fuel filter itself which refers to the filter in-line with the fuel line going to the engine.

Good luck!

 

Cool, thanks...

One last question:

Just curious: would this be true even if I hadn't already opened up the fuel system to remove the rails, etc?

Well, it's a bit a safety issue, in that if you don't fuel will spray out of the connection until the system depressurizes. Some people don't bother, others do. Just don't have any ignition sources around while you are doing this. Always a good idea to have a fire extinguisher in close proximity, in case of an "incident."

The fuel system can hold pressure for quite some time, on the order of weeks, so it's just something to be aware of.

 

Awesome, thanks for all your help.
