Fuel Filter/Fuel line problems
 

I have a 99 bonneville se. I recently replaced the ignition modual and when I went to go take it for a spin it started up nice, sounded great. But went to hit the gas and it didnt want to go over 10 mph, I was like what the hell. My fuel pump is good cuz i hear a nice huming coming from my gas take when i turn the ignition on. Im in the process of replacing the fuel filter but I cant get the damn thing off if my life depended on it. In the process of trying to take it off I twisted the metal fuel line and now it has a little hole in it. I figured I could just replace the fuel line from the filter on up to the engine. would you recommend i do that or what is anyones input on that? Im so confused on what to do. 1) cant get the filter off 2) I have a pin size whole in the fuel line now. What should I do? Or is the fuel filter the problem?

This is how to change the filter.

The lines are high pressure, changing the whole line is a good idea.

As for your problem. I would suspect the TPS before the filter in this case.

X2!

Change the line first. If your filter is partially clogged and restricting flow and pressure, you don't want to change the filter with a fuel line issue down stream of it.

Well regardless I know im gonna need to change the metal fuel line from the filter on up i was just curious if it comes in sections or is it just one line that goes up to the fuel rail? And if you have a picture of where the line starts till it ends so I have a genarl idea of what Im getting into. It doesnt look like its that hard. And when I go get a new one is it just called a fuel line, metal fuel line or what?

Get your car on some ramps and follow the fuel line from the filter up to the firewall. I think there might be a couple of sections between the filter and the fuel rail, but I'm not sure where the rubber versus steel is and how many sections of the steel tube there is. You can also get tubing, end flairer and a bender and make your own.

Im in the same dilema, i know i got a clogged filter and when i tried changing it i saw the whole freakn line rusted so i didnt bother changing it..... will this thing crack and crumble on me or should i let it be?

IMO...never take chances with brakes, tires and fuel lines. If you have a fuel line that is rotting, you are just asking for an opportunity for a fire. Take care of it now!

Keep in mind, the fuel is under 45 to 50 PSI.

Was wondering when it would be opportune to change out the fuel filter... will the fuel keep coming through the line until there's no fuel in the tank, or will only the fuel in the line spray out?

Follow the techinfo procedure for changing a fuel filter. This will remove the pressure from the line. Then you can work on the line a little fuel remaining in the line will trickle out.

When considering how to fix a fuel line, we can review how we fix the higher pressure brake lines. Double flaring and uniions should be adequate, although I am not personally sure what is accepted in these cases. I do know that you should not use a compression fitting on a brake line as it will likely leak.

I've done a bit of brake line repair and believe the double flare should easily hold the pressure of the fuel system.
