In the gumout product line the 2 most powerful products are:
Regane Complete Fuel System Cleaner - 12oz Bottle It has a 30-40% amount of PEA, with a Kerosene carrier. It will treat up to 25 gallons. Although if you have a smaller tank it will still be perfectly safe. It cost like 5.32 at Walmart
The next most powerful cleaner is
Gumout Large Vehicle Complete Fuel System Cleaner - It comes in a larger 20oz gold bottle. It contains the exact same percentage of PEA(30-40%) as Regane, just more of it. It will treat up to 35 gallons. I would not use it all at once in a small(12-15 gallon) tank as it made mine run a bit rough at that high level. Instead run 2/3 of it in a new tank and then when you are half empty, top up and use the rest of the bottle. It is about 6.99.
If you dont mind measuring out doses, I would go with the large vehicle bottle. You get more for your money.
Regane 5.32/12oz = 44.3 cents per oz
Large Vehicle 6.99/20 = 34.95 cents per oz
