Hello i am having an issue with my GS3 that almost as soon as the low fuel light come on the car starts sputtering. Its not a big deal for me since I usually dont let it get that low but my wife is driving it and she is a little more careless. And I really dont want her running out of gas.

I did some research on this when it first started a few months ago and I say that some people had said that is could be that the float is stuck on some baffleing in the tank but when I replaced the filter on the pump I made sure that the float was good.

I just wanted to see if anyone else has had this issue and knows how to fix it.

Thanks

Replace the fuel filter and run some cleaner through the tank, see if that helps... If not I would lean towards a bad fuel pump on it's way out..

I would say your fuel pump is going out too. I had the same issue with my e36. Put in new pump and I was good to go. However, I did replace the filter also. But it only made since to do both.

I replaced the filter on the pump already and it is still doing it. So yall are thinking that when the fuel level is low that the pump is having a harder time pumping the fuel???

Most of the pumps I have replaced usually come as an assembly with the sending unit and pump as one unit. When I search on rock auto it gives me a few options but it looks like it only comes with the electric pump it self.Here is the link.

When you changed the filter it's possible that you very slightly bent the rod that attaches to the float and threw your gauge off a little. I think that's what I did and there are some threads about it here.

I pretty positive that I did not bend the float arm. And it was doing this before I replaced the filer.

Does anyone have any other ideas on this one??

If you were going through the hassle of changing the fuel fiter, it would of been best to just replace the whole fuel pump.

Changing the filter is not a big job, it only took like 20 min.

I just want to see if anyone else has had this issue with there GS and if so what did they do to fix the issue.

So I guess replacing the fuel pump is really the only option?

I just changed my filter and strainer. When I filled up, it under-read by about 1/16th. So not quite full. It's possible the float arm is slightly out.

But before that , what I did to make sure it's not the pump is that I ran the car down to "E" fuel light and all. Then I changed the filter.

I drove it for a bit after the repair because I had already looked inside the tank when I was doing this and knew it was at roughly 1/16.

No hesitation or kickdown problems or sputtering but it is running a little rougher. But much much better performance.
