WOOOOOOOOOHOOOOOOOOOOOO!!!!!!!!
 
As I understand it...the science behind it is that the fuel causes "varnish" on the level sensor and the Techron dissolves it...It was my post and I've never even tried it, only read about it.....headed to the auto parts store tomorrow....lets keep the rest of the world posted as to how we do !!!

Just thought I would let you know that Walmart has the Techron additive and it is only like 4 something a bottle . Probably a lot cheaper than a parts store , hope you have success!

well maybe we have jumped the gun a bit. Although my gauge is now registering other than full or empty,it is still bouncing around . I will keep you posted ,maybe after a tankful or 3 we will have good results!

I'm going to do it 3 tankfuls in a row and see what happens...haven't driven it enough yet to expect it to move...if the theory holds correct and it is dissolving the varnish off of the sensor...perhaps at will take a little patience...I'm also going to put it in a little stronger for the second 2 tanks, i.e. if the bottle says treats 20 gallons, I'll try to have less than that in the tank when I dump it in....

Found this TSB# on the web...thought it might be of interest....I looked this stuff up and the bottle even looks exactly like the Techron bottle....who knows??????

GM Fuel System Treatment PLUS
GM Fuel System Treatment PLUS, P/N 88861011 (for U.S. ACDelco�, use 88861013) (in Canada, 88861012), is now available.
 
Added Benefits and Uses
The PLUS portion of GM Fuel System Treatment PLUS is the addition of a filmer additive that, when used regularly, can protect fuel system sending units from the corrosive effects of certain sulfur contaminants found in some of today's gasoline.
 
Sulfur contamination can disrupt electrical continuity of certain fuel sending units and lead to erratic or false fuel gauge readings. With scheduled usage, GM Fuel System Treatment PLUS protects against the effects of harmful sulfurs in gasoline.
 
You Get Four Benefits
One bottle of GM Fuel System Treatment PLUS added to the fuel tank at each oil change:
 
� Cleans -- Sulfur corrosion from fuel gauge sending units.
 
� Prevents -- Harmful sulfur components from attacking sensitive fuel system electronics.
 
� Protects -- By coating metallic surfaces of the fuel system.
 
� Removes -- Engine deposits left from use of poor quality fuels.
 
GM Fuel System Treatment PLUS will replace the original GM Fuel System Treatment, P/N 12345104 (in Canada, 89020804). The original formula may still be available for a limited time, and provides the excellent Fuel System Cleaning aspects of the new product without the filmer.

I was just wondering would the fuel sending unit be the problem? I have already changed the fuel level sensor, is the sending unit the same as the fuel pump? I wouldnt think the fuel pump would be the problem it either works or it doesnt, right?

I believe the level sensor and sending unit are the same part, 2 different names - don't have the book in front of me to be 100% sure
 
you are right, pump either works or it doesn't.....
 
Even on Chevron's website, one of the benefits of Techron that they list is that it frees stuck fuel level sensors....we'll see how we do...

have you had any results yet with the techron ? I am on my second tank and things are the same. I was thinking if the techron is for cleaning the sensor in the tank then i am wasting my time cause my sensor is new.Do you think changing the whole pump would fix my problem?
