Here are answers to a few commonly asked questions . . .
How do I know if I have a fuel contamination problem?

A few possible indicators of fuel contamination are as follows: 

        - Engine runs roughly, or not at all. 
        - Fuel filter(s) clogged or require continual replacement or cleaning.
        - Reduced flow from fuel lines or clogged completely. 
        - Excessive smoke from exhaust. 
        - Engine does not start easily.


How much does it cost to polish fuel and clean the tank? 

The cost is a function of size of the fuel tank, amount of fuel remaining in the tank and the level and type of contamination in the tank. Additionally, travel time, accessibility to the tank, and other environmental factors and requirements which must be accommodated will be factored into the cost of our service.


How do I prepare for a service call from Maine Fuel Polishing?

If you can, make access to your tank as easy as possible. If it is within your ability to do so, reduce the level of fuel in the tank to between 10% and 25%. It is important to leave some fuel in the tank. The remaining fuel will be used as a carrying agent to transfer out the contaminents from the tank. The contaminated fuel drawn from the tank is filtered to remove contaminants and returned to the tank continuously until the tank is free of contamination. Also, present our staff with any details you may have about your tank location, size, construction and access. Sharing the details will reduce the time we spend to provide our service and the resulting bill.


Does Maine Fuel Polishing ensure my engine runs smoothly after the polishing the fuel?

No, our job is to address the first step in the process to get your motor running again; WE ENSURE YOUR FUEL SUPPLY IS FREE OF CONTAMINANTS! It is the responsibility of your designated mechanic to work the problem forward from the fuel tank.


How does Maine Fuel Polishing know when my tank has been cleaned?

Our fuel polishing machines are designed with gauges that indicate pressures for pickup and return lines. When the pickup pressure gauge is within an acceptable range and does not have a positive change in pressure for a period of 20 minutes, the fuel has been cleaned sufficently of contaminants and the job may be terminated. Additionally, we will do a visual inspection of the inside of the tank via "light and mirrors" to ensure "debris pockets" have been cleared and the fuel has an acceptable level of clarity.


Will I have to have my tank cleaned more than once to address a single incident of fuel contamination?

Possibly. Because some tanks have baffles and odd shapes that are unreachable through existing service ports, fuel gauge ports or tank fills, contamination may still exist in those hard to get to areas. Typically, the contamination in those areas becomes suspended in fuel that sloshes around in mobile tanks and may require additional cleaning to reduce the overall contamination to an acceptable level. The best way to keep fuel contaminants at a minimum is to make fuel polishing part of your regular regimen of maintenance procedures.


How does Maine Fuel Polishing test my fuel for suitability after cleaning the contaminants from the fuel and tank?

If contracted to do so, we will take a fuel sample from the tank and send it to a lab in Maine to be tested. Upon recepit of the testing results, Maine Fuel Polishing will share the results with our customer. If further treatment is required, the customer will be informed and the remedy discussed.
