2002 Silverado 5.3 Fuel Filter Rplcment

[Gito]

Is there a need to de-pressurize the system before replacing the fuel filter on a 2002 5.3 Silverado or can I just remove the gas cap from the gas tank and replace the fuel filter..please advise...Im hearing different recommendations..

I'd depressurize the fuel line, unless you like getting fuel sprayed all over you. The easy way is to get a screwdriver and a rag and press in on the schneider valve on the fuel rail to release the pressure.

 

[Gito]

got it...probably the same place where you check fuel pressure...

 

[strongt]

yep.

On a 2001, I have always just let it sit overnight with the cap loose. There never seems to be enough pressure to make the fuel spray out.

Watch for O-rings on the lines. They don't come with the filter, and I have a note to myself to check them next time.

Is there a part# for the O-rings on the lines? Do you recommend dealer or can I get them at a local auto parts store?

I have the same truck basically, and I just pull the fuel pump relay from the fuse box and then try starting it a few times. Leaving the fuel cap off will help too if you want. I sometimes just crack the fuel lines (one side will do) and let it drip slowly for a few minutes and then come back when its mostly empty. Gasoline will still rest in the frame channel, so stick a rag in there to soak up any residual fuel. I anti-seize the filter threads and fuel line nuts good so I don't have any corrosion problems the next time I change it. Good luck.

I forgot to write that I usually do not replace the o-rings, even though they recommend them. If they look fine, I put some vaseline on them and call it good. I've changed my filter 4 times doing it this way with no issues. But Autozone does sell them if you want to replace them.

I've got a 99 silverado with the 5.3. The fuel pump and fuel filter are combined on this model year. Did they do away with that dumb idea after the 99 model year?

Yes they did, my 2002 has the pump and filter separated..I believe in 2003 the filter and pump once again unite. Seems like these 2003 pumps go pretty far though. I know someone who has approx 277,000 miles on the original pump and still going. My pump went out at around 150,000.

My '00 Silverado fuel pump puked out at 140,000 miles. That was fine because the fuel guage was not working half the time anyway. A new fuel pump (expensive, even fixed at home) solved everything. I do like that my truck has the filter outside the tank. Peace of mind every 50,000 miles for $20.

In the Chevy Impala SS -RWD - world, the fuel pump and strainer are a weak link. In the 94-96 Impala's there was also a nice fuel filter mounted on the driver's side frame. Easy to change and inexpensive. The guru's on the Impala forum discovered the fuel pump harness was the reason for most of the fuel pump failures. The tiny gauge wires were burning up due to the current. There was a factory upgrade and other aftermarket harnesses also went to bigger gauge wires. Now if you install a fuel pump with the heavier gauge wire harness, it will go much longer.
