I tried to replace my fuel filter the other day on my 2000 4runner. I had a bucket under the filter. I was suprised by how much fuel sprayed from the fuel line when I started to disconnect the fuel filter. I ended up resecuring the fuel line and quiting. Would the fuel flow have slowed if I continued the replacement?

 

vent the gas tank first by opening the cap for a second. did the fuel pump in my 83 and at first it seemeed like it wanted to empty my tank because of all of the gas spraying out.

 

I took the gas cap off also and all I had was a slow drip. About 1/2 a pint of gas came out.

-99 Limited

 

its normal for th gas to spray out like that, but it slowed to a drip after a couple of seconds when I replaced it on my 2000 Runner. it seems like a lot but 1/2 pint seems normal.
the hard part is trying to tighten the NEW fuel filter, took me like six times to finally get the thing on without any leaks

 

When I replaced the fuel filter on my 99, I cracked the front line loose just until it started to drip. I put a bucket under it and left it that way for a while. When I came back to it most of the pressure had dissipated and I didn't have any spraying of gas when I removed it the rest of the way.

 

Thanks - I tried again with more confidence that the gas pressure would decrease. The spray eventually became a drip, and I switched out the filter. It wasn't too hard. Glad I wore eye protection.

 

Eye protection is good .One time I was working on a car with a friend of mine and he got a little trigger happy with the p-b blaster and sprayed me in the face . .. let me tell ya it feels just like pepper spray ..

 

Pressure is between the pump and the injectors, so venting the gas tank is ...

 

There is often some pressure buildup in the tank. Venting it may help, but not much. You will probably get less than 1/2 cup of fuel from the lines & about a cup from the filter.

 

Gas cap has nothing to do w/ it. Loosening it at the filter is probably the best thing to do. EFI has very high fuel pressures.
