is their any gas additives that i can use to clean out the unit if its working properly
Do you mean the actual fuel sender or the combined fuel pump and sender.
I am puzzled why you feel you have to clean it?
Usually if it is not working it needs to be replaced.
If I was faced with this problem I would only use gas (Carefully)
I recall Sulphur additives in the fuel damaged lots of fuel senders in the past.
Could you give a little more detail

the gas guage moves around alot. more than the usual and thats the only thing that i can think of that would make it do that. the fuel sending is exspensive and i wanted to know if its not working correctly would it affect the gas and the guage.
what kind of car do you have?
year, make, mileage, mods.
pull the tank out knock the clamp off the tank when u have the pump/spending unit the a then stick with wires i u want u can clean with carp cleaned it probly have crocin on it i did mine like that and it workes fine....ir the wire is broke i will have to replace the hole thing but not the pumo i like i was gonna be like 100.00 for mine and i have a 1991 pontiac sunbird le with 3.1 fi
lookes a little like this
I like that, Chris.
There can not be too many people who have the sender resistor handy to photograph!

i wish i could do that but dont have the tools or the help and i dont want to mess anything up cause i dont what the hell im doing.
does the sending unit affect the gas or mileage and would a mechanic be able to do this or would they try to find the easy was out and tell me i have to replace the whole thing.why does is cost 300 dollars does it come with a new pump and everything.
so its does i only fixed to because i like to kn ow how muck gas i have...lol pro jus the car i dont think it coe with the pump idd just adl some friends or nabors if they could help u..
Hi Hydeyoshi
the fuel sender is just a variable resistor and as Chris says it's job is only to make the fuel gauge read how much fuel is in the tank.
A float in the tank (it's part of the sender) moves a contact over the resistance, which Chris was holding in the photograph.
The resistance should vary from 0 (Zero) ohms when the tank is empty to 90 ohms when the tank is Full, i.e. the float moves the contact dependant on how much fuel is in the tank
When the Fuel sender reads any resistance value in between these figures the fuel contents gauge will read somewhere in between Full and Empty.
The sender will NOT effect how much gas you use per mile, other than maybe leaving you stranded if it is not reading correctly.
Hope this helps
