Re: Gasoline Evaporation of 3/4 gallon per week ???????
I fill the tank and stop filling when the auto-shutoff occurs on the pump. When the tank is "full", I can usually drive about 40 miles until the needle on the gas gauge drops below the "full" line which equates to about 6 gallons (at 7 miles / gallon). This is how I first noticed the problem - I would take off on a trip and my needle would be below "full". On several occasions I immediately stopped and filled up the tank to determine how much gas was missing. It is pretty obvious when I store the motorhome for 6 weeks and the tank is only at 3/4 full after parking it w/ a full tank. I suspect is is evaporation, but can't figure out where/how it is evaporating from and I would also expect an engine fault light if I had some kind of hole in the top of my tank (which I am unable to see)...I had several people tell me that gas could/would not evaporate that fast. (as an experiment, I placed a gallon of gas into a bucket under my motorhome the other day and when I came back 10 hours later, about 75% of the gas in that bucket had evaporated....)1.1KViews0likes0CommentsRe: Gasoline Evaporation of 3/4 gallon per week ???????
I started seeing a similar problem about 6 months ago on my 2002 E450 Coachman motorhome. I always fill up the gas tank when I return from trips and started noticing that I was missing gas when I started my next trip. I appear to be loosing 2-3 gallons of gas per week (the rate of loss seems to be somewhat consistent regardless of how long I store it.) I am not seeing any leaks where I park the vehicle. Then thought someone was stealing the gas and added the lockable gas cap. Last month I took it to the Ford garage and they could not locate any leaks or smell gas under the motorhome. They also checked the computer for engine code faults and did not find any. I'm stumped. Does anyone have any suggestions?1.1KViews0likes0Comments
