Brian,

I have read all the responses and noted that no one has answered your first question regarding having the rusty tank cleaned. I
would suggest you Google "Fuel Tank Cleaning, Washougal WA" This should bring up companies near you that can perform that service.

I did that in Houston and found a couple of companies, however, their services were not cheap, I got them to provide a "rough"
estimate after providing the measurements and capacity of the tanks and was told $400 - $500 per tank.

I store my coach in Houston 8 months per year and before I do so I fill the tanks all the way up (adding the correct amount of
Stabil) until I can see fuel in the filler neck at a station about a mile from the storage facility. I drive it back, pull it into
the "garage" and shut it off and don't run it again until the next year when I return. I've been doing this for six years and have
had no problems.

Subject: [GMCnet] Fuel tank cleaning

Just getting ready to park the coach for the winter as my season is over. We had it out 5 times over the summer and after trip 1 I
discovered rusty
water in the rear tank, front tank had none that I could drain out but the rear tank had 3-4 gallons of water in it, hard to say
exactly how much but
I drained a bunch. To get through the season I added a fuel water separator / 12 micron filter thinking that would be enough but
apparently the inlet
filter on the QJ is finer than 12 microns and on the second outing I only made it 30 miles before it plugged. Fortunately we were
still in town and
got 3 filters from a parts store and took 2 more to complete the 320 mile round trip. I added a bunch of Neodymium magnets to the
bottom of the tanks
to try to lock the rust in the tank and that seems to have helped, the last trip was made on 1 filter. Now it's time to drop the
tanks and get this
problem taken care of, I'm going to replace all the fuel lines while they're out as well and probably add an electric fuel pump as
well as fixing the
sender in the Aux tank, it always reads full.

Anyone have any suggestions for getting the tanks cleaned out and what about these gas tank sealers that are available, are they any
good? I have read
mixed results with them and with tanks this size it could be a pain to apply properly. of corse final decisions will be made after
the tanks are out
and inspected.

The other question I have is where did the water come from?

Thanks for any insight.
