I don't suppose that this or any other treatments helps to get rid of the corrosion?

I did that for about a year, then suffered catastrophic corrosion failure, resulting in a major fuel leak right over the tail pipe. I'm talking a 1 ft dia. puddle in about 30 seconds. At that point it was too late to take the cost effective method and a dealership visit ended up costing me over $1200 by the time I was all done. Corrosion attacked the sender and lines and rust fouled the fuel pump. Wasn't pretty.

Additionally, a coworker here had his Buick do the same thing, but his wife was on a long trip on the interstate and did not know anything was happening until someone honked and motioned to her that she had a problem. She looked back, saw smoke, stopped, grabbed her purse and ran from the car. Total and complete automobile meltdown. True story!

Anyway, the point of all that was to warn you to be sure you don't have any rust up there by the sender and lines and if you do, I recommend replacement now, rather than later. Just my opinion.

Well guys, I was going to go to the local GM place and buy some of the fuel treatment and put in my pickup and the Bonneville. But I while I was at WalMart in the Auto section, I stopped and looked at the new bottles of TECRON. It says right on the label now that it helps with the corrosion problem on fuel sending units. I bought 2 bottles each fo rthe Pickup and the Bonneville. I out them in and the Pickup has already srtaightened out.

Last summer I drove my Corvette to Bowling Green for a Corvette rally. One of the deals they had there was a Corvette Tech Specialist, he really sung the praises of Tecron fuel additive, now I guess I'll use it more often, in all my GM products. Try it, it might help with your problems...well maybe not if it has been a long time, but if you don't have the problem using it might keep it from happening.

I'm a secret Techron user, or was. I've now started using Redline additive. Both have worked for me to keep things clean and running smooth. Well worth the $6 or so they cost, IMO.

I like the TEchron best too. I'll check the bottle I have in the garage now. I use it about 3 times a year on both cars. Just one serving each time. Just in case. Car always runs better when it goes it.

I guess if you are lucky, you might have a Cheron station down the street, if so I believe that all their fuels have Techron in them. We aren't so lucky in my part of the world, the only top tier gas staions we have are Phillips/Conoco, and they don't have Techron in them.
