  1. First off, hello and thank you for taking the time to read this. I will start with specs and how the truck is put together to make this easier to understand. My truck is a 97 Chevy C1500. It originally came with a 4.3 Fuel Injected Engine. However the guy that owned it before me swapped in a 87 block style crate 350/5.7. He switched it over to carbeurated. Put a mechanical pump on it. Now when he ran the lines, he left the old fuel pump unit inside the tank. He just disconnected the power to the electric fuel pump, and the mechanical fuel pump on the block pulls its fuel THROUGH the inactive electric pump. (according to what he told me, still need to pull the tank and verify this, but wanted to get information first) So there's the basics. The issue im having is that my fuel gauge does not work. It is currently pegged about an inch or two past full. Now, Ive been told varying things. One person tells me that the fuel sender works independent of the electric pump, and that all i need to do is replace the sender and hook up only the level wires and leave the power to the in tank pump disconnected. Another tells me that the electric pump HAS to be powered for the level sender to work, and there's now way to make it work with myy setup. That's not even including the fuel level buffer module or whatever that i just heard about today -_- My question is this. How does the sender work in detail, and what is my best option for diagnosing and fixing my fuel gauge? Is there a way to make the fuel gauge in the dash work with the current setup, or do i need to get a separate specialized gauge and install it? Any and all help is appreciated. If y'all have any questions please do ask and i will do my best to answer them in an effort to get this issue figured out. (Picture attached. Harness wires: Purple wire is level sender wire. Gray wire is the power to the pump. Black wire on its own is i think the ground for the pump, black wire going into plug is ground for sender, according to the wiring diagram i reviewed.)
  2. After I filled my one of my gas tanks. The fuel now reads way past full and doesn't move to just under half a tank until it's bone dry. Do I need to replace the sending unit and if so do i need to remove the truck box to do so? Or Is there any tricks to resolve issue? I seen a you tube video where a guy used a magnet to move the fuel gauge needle to correct location?
  3. alright so ive been having an issue with my gas gauge lately and so far, ive had no luck in fixing it. ive been counting miles and watching my "gallons used" on the panel. now my gauge is always on E and the light is always on, and its been like that since i bought the truck. Now a little while after i bought it the cluster panel started acting up and i was hoping that having it rebuilt would also fix the gauge, but unfortunately it didnt. this leads me to believe that its the fuel sending unit. because on the panel on the fuel range in miles it says fuel level low. but on the screen that counts how many gallons youve used since you last filled up, it still will tell me how many i have used and i can judge how much gas i have based on what that number is, but today i had forgot that i didnt reset the gauge right away, and ran out of gas because i thought that i still had 2 gallons left in the tank. so you can see why i want to get it fixed because i dont want to run out of gas on the side of the road again. so heres the question. now i have a 2004 silverado gasser, 4.8 V8 2wd ext cab with a 26 gal tank. i found a universal fuel sending unit (im guessing made origionally for a boat) in the marine center at Bass Pro. do you think that it would be entirely possible to make that sending unit work? or should i just shell out the money to get it from an auto parts store? sorry for the long post, but i had a lot of info to give thanks!
