I've watched the gas gauge while filling. Most gas first goes in the main tank. As that's a straight shot back to the main tank. To flow into the front tank. That gas has to make a 90 degree turn to the left. I have one of those fill tubes. I'll test my thought tonight. Bob Dunahugh

I hear of owners putting a stabilizer in their tanks. And they think the job is done. Main tank. Yes. I just drain my collector cars. Bob

Seems to me that a separate fill system for each tank
would work, but probably a huge problem to install.

I don't see how that can be done.

Which begs the question is fuel stabilizer necessary and does it work. How much time, if any does it buy you? Any side effects? I had to put my coach into emergency service in May and it had been parked since Oct 2019. Connected batteries negative cables and go. Filling water tank took longer. I don’t add any products to my gas or oil. I have seen E10 go rancid, but that was in a collector car that sat 15 years. I just don’t see any issues with one season storage. Still on Qjet. I’d rather spend the stabilizer money on fresh gas.

John,
I'm with you: I see no advantage to spending time/money on fuel
stabilizer. I've never had a problem that I could remotely attribute to
"old" gas. Even when I've filled too many jugs for the lawn equipment and
had it sit for a year or more, there's never been a problem, even with the
notoriously finicky 2-stroke engine. I will admit to having bought premium
gas for those for a while -- but I've now gotten out of that habit. Even
the older 2-strokes seem to be satisfied with 87 octane 10% ethanol.
Similarly with in-tank condensation: Knowing that the fuel cap on my GMC
has a 1 psi venting pressure requirement, I don't see how enough fresh,
humid, air can get into the tanks to condense a significant amount of H20
-- especially with all the ethanol in there to combine with it. Maybe it's
not really 90+% humid here! :-)
Again, until I have problems, I can dream up more interesting things to
worry about -- like the Wuhan Virus.

We store alot of stuff in MN. always wonder why I live here!
I would say in my experience, the factors are quantity of fuel and time. a 1/2 gallon tank on a weed whip, is probably going to give you problems after 6 months of 10% ethonal fuel in storage. that same 10% ethonal gas in 50 gallon amount in my GMC, gives me no issues stored from November to April. I have never put sta-bil in the GMC. but usually the gas is never more then 4-5 months old.
my 84 mastercraft boat, with a 351, I generally store full of gas(10% ethonal), and put in sta-bil just after labor day, and pull it out after memorial day. the sta-bil is probably cheap insurance. I never have a problem, but I can for sure tell that 1st tank of gas does not run as strong or well. after a day on the lake, and I re-fil 50% of that tank back up with fresh gas, the next trip on the lake the engine is sounding better and has better response. I think this is year 17 or 18 of running that boat 3 months a year.
We have small engine equipment at work, that usually needs a carb drain(honda motors for pumps ect..), after then sit for the winter or summer with 10% ethonal gas in them. Honda's seem to just need the fuel drained and fresh gas put in. Briggs/stratton powered stuff, the mechanics toss them, or swap out a carb. our wacker tampers seem to be something our mechanics have a field day with getting all those back running in the spring.
I would never recommending draining gas on anything that has a metal gas tank, like our GMC's. in our 80 some degree temp swings, things rust. I would rather clean out a varnished up tank, then one that is coated in rust!
