asdf I noticed that some of your products contain chemicals known to the state of California to cause cancer and birth defects? Should I be worried if I use your products?

7 July 2016

What you are asking is in reference to California’s Safe Drinking Water and Toxic Enforcement Act of 1986, better known as Proposition 65. Proposition 65, or Prop 65, affects all products sold or distributed in California. In its simplest form, Prop 65 can be considered a consumer “right-to-know” or product labeling law that informs consumers […]

Is Gumout safe for yellow metals? I.E. Copper Fuel line? Is Gumout safe for a diaphram style fuel pump with a neoprene diaphram? Is there a gumout product specifically designed for cleaning out fuel lines/fuel tanks that have long since been “Dry” — as in the issue is less because of gelled gasoline and more grease, dirt, oil possibly that have entered unsealed parts of the system over time?

Gumout is safe for both copper fuel lines and neoprene diaphragms when diluted in fuel. If dirt and grease has entered the fuel line use the new Gumout® Regane Auto Parts Cleaner Degreaser aerosol which has a straw that can reach deep into the lines. If that is not available use Gumout® Jet Spray Carburetor […]

I have converted my stock fuel system to an aftermarket one. The stock gas tank has been replaced by a fuel cell packed with anti-slosh foam and the cell is made out of plastic. The fuel lines are a rubber lined stainless steel braided line. The fuel pump is also an aftermarket unit that can cover the twin turbos thirst. My questions are as follows. Will pump gas cause any problems with the cell foam, the cell itself or the fuel line material over time with the current amount of gas/alcohol mix? I have run E85 before when the fuel system was stock but now can I run E85 again without worry? One last question. Can I use your products and other’s like fuel system cleaners without worry. All this comes about from the fact that race fuel cells are made to work with race gas and over a short season not in a daily driver.

All Gumout products are compatible with standard OEM fuel tank components. However, specialty aftermarket or racing components should be tested by the manufacturer. In general if the component is compatible with pump gasoline, it will be compatible with gasoline treated with Gumout®. If E85 is run in the vehicle the Gumout® product to use is […]

I have a classic 60s muscle car with a carburetor that gets stored from November to April every year. It is in a dry garage. Do I have anything to worry about with regards to E-10 pump gas? If so, what products should I be using? Is it better to fill-up before the car goes into storage, or keep the tank close to empty and add fresh fuel in the spring? Any storage tips would be appreciated.

24 June 2016

We recommend filling the tank with fresh fuel before storage to displace the air. The tank will still breathe slightly, but the water incursion will be very small. Before filling the tank add Gumout® Multi-System Tune-Up to prevent fuel oxidation (gum and varnish) and corrosion protection (rust and pitting). Run the vehicle to deliver treated […]

Doesn’t water tend to get in fuel tanks with or without ethanol? Doesn’t water tend to get in fuel tanks with or without ethanol? Adding a bit of ethanol or methanol to the fuel tank used to be a standard recommendation for getting rid of accumulated water, since the alcohol acts as a bridging solvent, putting the water in solution so its drawn into the engine and “burned”. Stops motorcycle tanks rusting out, which they tend to do along the bottom seam where the water collects. Separate water seems likely to be just as, or more, damaging than water in solution.

Water can condensate in fuel tanks at the station and in your vehicle – the more hot and humid the climate the more this will happen. If the fuel doesn’t sit for an extended period of time the ethanol will pull in water where it will be burned up in the combustion process, but when […]

I had an issue recently where a gas station accidentally put diesel in the gasoline tanks underground. As a result I had to drain the fuel system in my vehicle and clean up the fuel system parts. After cleaning I fueled up with fresh gas and a bottle of your REGANE product. Will GUMOUT products help remove diesel fuel residue from a gasoline tank/fuel lines?

24 June 2016

Yes, keep fresh fuel and Regane in the tank for the next several fill-ups. The Polyetheramine (PEA) detergent in Regane® will help clean-up any deposits or contamination from the fuel and help remove any carbon that may have resulted from the incomplete combustion of the diesel fuel.
