We began having problems with surges & hesitations shortly after filling our tank at the local station. We called the station and the owner tested the station tank. Nothing showed up. The next day the problem with our car continued and the check engine light came on. We took the car into the dea…

Yes, and any dealer or shop who tells you that water is involved should be prepared to take a sample of at least a quart and keep it for your inspection.

Tell the fuel station of your complaint. Tell the fuel SUPPLIER of your complaint.

Fuel pumps are designed to pump liquid, and gasoline is not much different than water. I once had a vehicle into which a large amount (many gallons) of water was pumped. The mechanic disconnected the fuel line and used the vehicle’s fuel pump to empty the gas tank. The engine ran poorly for about…

Can water ruin a fuel pump? Maybe. I’m skeptical. As you are probably aware, air slips into the tank as you burn off fuel and that air can contain a fair amount of water vapor – especially in humid climates. The water then condenses on the cold walls of the tank at night and ends up at the botto…

The tanks would have to be leaking for this to occur. Ethanol should make water content a thing of the past. I too don’t see why a fuel pump would fail with water while not with a solvent like volatile. Fuel has no lubrication qualities. Now if it’s fouled with stuff contained in the water, that…

After doing a lot of research, and I mean A LOT!! I did testing on antifreeze in gas in 27 countries on 5 continents, summer and winter. After I finished my research 3 years later and got home to analyze the info, I realized I left the notebook with the info in Switzerland on a bus bench. All I coul…

Water in gas tank and possible ruined fuel pump

Maintenance/Repairs

Reference the old cold weather practice of adding isopropyl alcohol or “dry gas” to the tank to soak up water. Now that almost all gas contains at least 10% ethanol in the winter months, is there any need to continue the old dry gas treatments?
