SHE is absolutely paranoid about giving out of gas, Especially in the GMC.
Hyper-especially when we aren't towing a dinghy. If we give out of gas,
as we did several times when I was refurbishing the GMC, including a couple
of gas tank R&R's back in '98 & '99. "How can you give out ...", "Can't
you see the gauges...", "What do you mean you can't depend on them...",
"What are we going to do now...", "I guess I'LL have to start watching the
gauges...", "Why didn't you stop in the last town...", "Let me drive -- I
WON'T give out...", "I'm never going any where with you again...", "This
ALWAYS happens...", "How much gas do we have left...", "Seems like a long
time since you filled up...", "There's a gas station...", "What do you mean
it's $0.01 cheaper 10 miles down the road...", "What do I care if it's got
ethanol in it...", "How...", "Why...", "When...", ...
It's probably best she doesn't know that I intentionally ran the tanks low
while coming home from her brother's last Saturday, with no toad.
Especially since there was NO gas in the Aux tank and <2 gallons in the
Main when I drained them today.
Yesterday I jacked the coach up, removed the tires, and spray washed the
underside in preparation for today's efforts. Today I re-sprayed the
underside to complete the job of removing the ATF Rustproofing and other
debris, drained the tanks, and began disconnecting hoses. The 30R7 hoses I
installed in '99 are in surprisingly good condition. If I could be sure
they're as good on top of the tanks, I'd retreat from this project. But
I've already got 25' of 3/8" Polyarmour and the 5/16" should be here
Monday, so I'm committed. SO, I've got questions:
Several folks have commented, and posted photos, of what they've done for
top of tank connections. I expect to copy those ideas, probably with
compression fittings at the senders. What I don't remember having seen is
how y'all have gotten the lines down off the tops of the tanks and where
the necessary connections were made. Maybe it was too painful to repeat?
Looks to me like it could be. Did you leave the off-tank ends straight or
curve them down the port sides of the tanks? Connectors there, or then
bend forward? I can't imagine being able to run the Main lines other than
off the port side, but the Aux lines might go straight forward over the #5
crossmember. I dread trying to make any connections in the narrow tunnel
with the filler tube, both because of the limited work space and the
interference with fitting the filler tube rubber connectors. How'd y'all
do them? I really don't want to follow the easier route of using rubber
connectors.
Thank goodness I took care of all the pressure lines forward of the
rear-mounted electric pumps when I installed EFI. All I really have to
fool with now are those on top of the tanks and the vent lines -- of which
there will be two to the front, by the way.
Suggestions of all sorts solicited!
Ken H.

KEN, run on the top half of the tanks. Your filters will stay cleaner
longer, and she might not kill you in your sleep<V.B Grin> Duane said that

Jim,
Sure wish I was with Y'All. That's a trip I really wanted to make -- as a
follow-on to an extended visit to the NW US & W. BC, which also couldn't
happen this year.
I don't know whether you're putting me on or not! You know better than
most the fallacy of that old saw "don't run the tank low because you'll
pick up the junk in the bottom of the tank...". The junk in the bottom of
the tank is what we ALWAYS get -- that's where the pickup is! :-)
Speaking of which, today I got the tanks down and completely drained. They
still look good inside. And the topside lines were good enough that I
probably could have left them alone for the rest of my GMC career. But
they're gone now.
The worst thing I found was the socks. They were still in place, but
beginning to deteriorate badly. The first came apart at the seams as soon
as I started handling it; the other started shedding tiny fibers as soon as
I handled it. I cut as much off as possible with scissors, then charred
the rest with a propane torch and brushed off the residue. I'd forgotten
the exact structure of them so never before protested the term "blow the
socks off". That can't happen to one made as mine were -- the sock it
firmly and permanently attached to the pickup tube. A more appropriate
term might be "rupture the socks"; I suspect the stitched seam comes apart
when a large volume of compressed air tries to get through the sock -- I'm
sure it does NOT come off.
My gauges had become progressively more unreliable so I refurbished the
senders. The main problem was the electrical terminals. I don't remember
it, but I probably replaced the insulators for those in '98 or '99. If so,
I chose an incompatible rubber for those seals; they were completely
deteriorated. I made new ones from some appropriately sized Nylon
shouldered bushings I had. Hopefully that can withstand the ethanol. I
disassembled the first of the sender housings to examine the resistance
element; it and the wiper were in surprisingly good condition. I don't
care much for the electrical design, but didn't change it -- fuel level
gauges aren't that important to my fuel management protocol. Opening the
housing was a mistake: One of the locking ears for the cover broke off.
Brazing, given my poor and long-unused skill, wasn't a good option so I
wound up using JB Kwik; that should do it. I didn't disturb the housing on
the other sender: That tab wasn't used; the cover had been TIG welded on!
The resistance check was as good as on the one I tampered with anyway.
I'll probably lay off tomorrow and start the re-assembly on Monday.

Ken, I was thinking about trying to be funny. All the sock strainers that
were in-tank that I have encountered were the same as the ones that you
burned off with the propane torch. I have found them heavily varnished and
dried up. In that condition, they will not pass sufficient fuel for the
engine to run correctly. I have found some ruptured, and I suspect that is
what happens when an air nozzle is applied to the supply line. I think that
a metal in line filter similar to the VW Rabbit used would be a great one
to use. They are a 10-15 micron element, and will allow water to pass
through instead of blocking the flow like the 5 micron filters do. Most
have banjo bolt fittings with soft copper washers on each end. Good stuff.

Ken,
Here is a pic of my tanks at the point when they were about to go back in:
http://www.gmcmhphotos.com/photos/gas-tank-fuel-line-project-6-10/p34775-gas-tank-clean-up-fuel.html
I used Polyarmor on the tops of the tanks, only, and put a little kick in the ends of the tubes to make it easier to attach them to the appropriate lines next to the frame. I did not attach the Polyarmor to the tanks in any way, other than some duct tape (red, of course) IIRC. I DID put a short piece of rubber hose on the (left) ends of the hard tubing to act as a buffer between the Polyarmor and the steel tanks. Everything else went back in standard with barrier hose I bought from Jim K. Not cheap, or very inventive, but I expect it to last for at least 10 - 15 years. I have no problems filling the tanks either, even with the factory designed single vent.

Dan and others!
Using MS Word (or equivalent program), build
yourself a list of your sites needing passwords.
List each site alphabetically, tab over and
enter your sign-in name, tab again and put
in your password.
Give this file a name that you can remember
and put it in a "personal" file folder.
You can easily put new entries in or take them
out as needed.
I'm sure there are a few that you use often
such as bank accounts, eBay, email, etc. but
put your file where you can easily remember
it but might be quite a puzzle for somebody
else to even locate!
I have over 100 in my list! No way could I
remember them all, especially since I only
might use some of them once or twice a year!

Dan,
Download version 2.18 of KeePass and use it. You can have a unique,
KeePass-generated, unique password for every site you visit, with no
hassles and hardly any danger of compromise, even if your laptop is stolen.
You can even set it up so you can use it as a menu of sites -- click on
your choice and be logged on automatically. Hard to beat for free:

MS Word works, but to each his own, and I much prefer Excel. Searching and sorting are much easier for a list of passwords that is basically a database. I have columns for company, purpose, URL, username, email on record, password, comments for customer service ph#, acct #'s, etc. Works for me.
Be sure to back it up, and consider encrypting it.
