Fuel level kinda jumps a bit mostly flat lining causing the low fuel light to come on in the message center. My fuel gauge lies to me.

I understand that this is a common problem. I also understand that it is the fuel level sending unit. I also understand that a replacement fuel level sending unit is about $300. If this is the case, I'm thinking that a fuel cell is the way to go. Anyone have any experience with a bad fuel level sending unit?

Thoughts or ideas?

Anyone ever swap in a fuel cell?

 

your are right on everything you said. but how big of a fuel cell can you get? it would be a pita to have to fill it up if you drive a lot.

 

I dono what Im going to do. It would be nice to put a cell where the spare tire lives that would help with the trucks horrible weight distribution and traction. But you're right I would need a large cell to be happy with the drivability.

 

Anyone else have any input. I hear that I may be mistaken on the price and it is much cheaper then I thought.

Any have a take-out Fuel Sending Unit?

 

I have the same problem. I forget who it was, but someone on here who works at a dealership was kind enough to fax me a copy of FSU diagram. You don't have to replace the whole expesive thing, just something in it. Let me see if I can find it...

 

its from the wreck you had yesterday..... lol

 

Ya it is.

I pounded the dents out last night but now this
Its always something. (I also have a reoccurring SES light but that is going to be a different thread.)

 

The sending unit does come separately from the fuel pump. I changed one on a 2000 not long ago. The price was only $130-150 Cdn so it will be much cheaper in the US. The sending unit just clips onto the side of the fuel pump bucket.

 

yes im haveing the same problem. there are two different types our trucks come with rpo code TCU or TCF storm5.3 has an extra TCF he will sell to ya i believe PM him and ask laters, kevin

 

What is the difference between the TCU and TCF?
