Advanced Power Systems, makers of the Fitch Fuel Catalyst, have added in-line units to their product line. These in-line units are primarily intended for use in automotive applications, and in no way replace the drop-in units we use in our gas cans and recreational vehicles. Since we all own cars and trucks, it seemed logical for them to promote their automotive products to the same users of their drop-in units.
We asked Advanced Power Systems why they are now offering the in-line unit, as we figured this was not going to treat the standing fuel left in the gas tank, the main reason we use the drop-ins. The response was that many newer automotive vehicles will not allow the drop-ins to be installed into the gas tank. The in-line units treat the fuel as it is going to the engine, so you still get the catalyst reaction that delivers fresh fuel.
We’re also told buyers like to â€œseeâ€ their investment, and that the in-line unit is visible under the hood, where the drop-ins disappear. The in-line can easily be removed and transferred to another vehicle, while the drop-ins are pretty much in the tank for good. And, guys like to show their new stuff to their buddies.
APS claims modest fuel economy gains when using either style. We continue to experience the benefits of fuel that doesn’t go old or bad with our many drop-in units, and any engine fitted with a knock sensor and variable ignition timing acts as if a higher octane fuel is being burned. Seasonal units, ones that are not used constantly through the course of a year, all have the Fitch drop-ins in their gas tanks and we no longer experience any sort of fuel degradation. Every gas can, lawn mower, weed wacker, snow blower, any small gas engine, they all have one in the tank now. It’s really weird, but the catalyst acts on the fuel molecular chain length and keeps it fresh and ready to combust. In each instance, the unit fires right up after sitting for six, eight months. No greenie grungies, no stale gas, no wet plugs.
So, the in-line units allow installation on most any vehicle, and allow you to take it with you. They do not provide the â€œstabilizerâ€ effect to the fuel in the tank, however.
