Begin by opening your gas cap to depressurize your fuel line.
Taking out the pump fuse and starting the engine is the only way to depressurize the fuel lines as far as I know.

Yes, you're right. Maybe I should write "partially depressurize"? What do you think?
As far as what you recommended, i dont think that's entirely necesary but I'll add it to the write up. Regardless, a fair amount of fuel will be in there anyways.

Yah totally unnecessary, I think pumps on the 3rg gen 'leak' anyway. The logic behind it is the 'hard' starting; which is remedied by turning key to ACC for a few seconds to energize the fuel pump and build up the pressure.
And I did notice that 'hard' starting is present only after sitting for 3+ hours, otherwise it starts up fine, which I guess supports the hypothesis

on my 86 the fuel filter is right above the passenger side wheel. there was a little metal plate that i unbolted from the wheel well to make it easier. it would be even easier if you took off the wheel now that i think about it.

I only had about 200-300 ml of fuel come out.& the was very litte pressure.

My truck had about 120K miles on it when I changed it, and it definitely needed it. I don't think the previous owner had ever done it. I cut it in half to see how bad it was:

thanks i'll be wrenching on this as well (47k) on my taco V6 does anyone know if it's in the general location as the 4runner?
I'm on a quest to figure out why my taco gets ˟˟˟˟ty gas mileage compared to others avg 17mpg. I cleaned the MAF sensor today so next fuel filter

yeah, my truck gets horrid gas mileage, partly cause of the crappy k&n filter that clogs WAY to easy, and probably cause ive never cleaned the maf and never changed the fuel filter, or the spark plugs, or nothing.

Dont get me wrong, I'm not saying its not a good idea to do, because it is......but some vehicles dont have servicible fuel filters, take jeep wranglers for example, the fuel filter is located inside of the fuel tank at the pump....to change it would require you dropping the tank....saying "it unscrews, so that means its a maintance item" doesnt really make sense, because I cant think of one think on the vehicle that doesnt unscrew, unbolt or unsnap....
I dunno why I'm arguing against you guys since I do agree with changing it...heheheh

Newby here. '99 4Runner V6 SR5
I tried to replace my fuel filter last night, and could not get the compression fittings on the 'Out' side of the filter to reseal. Spent a couple hours taking it off and putting it back on, but it continued to Leak at about 1 drop every 3 seconds.
I ended up putting the old one back on and No Problems.
I did notice the inlet and outlet holes on the new filter are noticably bigger than the old one (probably about a milimeter). Could this have caused the leak? Did I get a bad part (Toyota Fuel Filter #23300-62030 )?

At any rate you're correct, it is worth changing since it's so easy and cheap to do.
