GM Fuel System Treatment PLUS, Fuel Sending Unit Corrosion and Fuel System Deposits
2006 and Prior All GM Cars and Trucks

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.

Its about time that they did something to prevent this problem.

I tried it and it seems to work better than Techron. Before if I was below a 1/2 tank of gas and the car sat for a few days..the problem with the fuel gauge would popup. So far after using the GM fuel treatment there has been no problem with the fuel gauge.

Sounds like a good fix. however, I think it is ridiculous that this is even necessary. so if this is the "best" fix, then GM makes more money because they sell the consumable fix over and over. What would be the need for a permanent cure when you make more money off of a problem? What next? I wonder about the truck steering column issue. Why fix IT when you will get to sell a lot more intermediate shaft/couplers? Maybe next they'll come out with a DIY DVD and sell it to help replace your steering shaft since you'll have to do it about every 12K miles or so!

I agree @ $24.00 a can it's a rip off....but it works ..so far the problem hasn't returned..
