I just purchased this 76 Glenbrook from one of the greatest Liars that
Washingstate has
that old saying buyers beware, I was beware but thought the guy was
sincere Oh well.
Has any one had any trouble with the fuel tank gauge and I know most
gauges are top mounted and need to have the tank dropped. In order to
make the repair. It looks as though this is one big tank are is it two
tanks side by side?? I don't suppose there is an access or can be one
from the top floor board.
Any help will be appreciated

Thanks Gary K7UJX1

My 1976 Palm Beach has 2 tanks mounted fore and aft. The 1975 and 1976
Service manual shows the pick-up & gauge to be mounted on top. The manual
further states that in order to replace the fuel tank gauge the tanks must
be dropped.

Good Luck,

The fuel (Tanks) are Two (2) . They are not hard to drop empty. The
straps come undone easily. Once you get the tanks down recommend you
change all the rubber and socks in each tank. I bought all the right
stuff but could not get the top off the tank to make the changes. I was
afraid to try to open the tanks without the right tool that is probably
needed to open the tank. So if some one out there has done this let us
hear from you. Thanks Chuck
 
Yes the sending unit(which includes the fuel pickup and vent) is on the top
center of the two 25 Gallon Tanks. The switch on the dash does two things;
energizes the electric valve under the drivers side of thhe coach to
switch to the AUX tank pichup, and changes the feed to the gauge on the
dash to the other sending unit.

We kicked around the idea of getting access from the top by cutting a hole
in the floor. This Idea was rejected because the tanks are push up tight
to the bottom of the floor. Besides, any work neccessary on the fuel lines
or vent lines (which is a common cause of leakage when filling up the
tanks) requires you to 'Drop the tanks' anyway.

Hint: Try to save and repair your current sending unit. The oriignals are
all gone and the aftermarket ones (at about $100) put out different
readings than the originals. I know because I have one of each, and
changing over the dash switch shows different levels when, if fact, they
are the same.

Chuck,

I'm sure there is a proper tool for it, but we just used a screw driver and
a hammer to get our senders out. You have to alternate hitting the little
tabs that stick up (being semi-careful not to break one off) so that the
ring turns until it can come off. Reinstalling works the same way, as you
just keep turning it until the stop tabs keep you from turning it further.

I would suggest getting new o-rings for the senders even if your originals
are good. The new ones have tabs that help ensure the o-rings are in the
correct position. With the old ones, the o-ring has more of a chance of
slipping slightly into the hole while installing the sender.

Ed,

We did it ourselves and had the same problem (lots of gas everywhere from
one of the tanks). One of the original style o-rings slipped slightly into
the hole. The problem is that once you put the sender in, you can't really
see the gasket anymore to ensure that it is still in the correct position.

I suggest using the new style o-rings which have tabs to pretty much ensure
that the o-ring is in the correct position. With the new o-rings, there
probably won't be a problem, but I would also suggest pressure (VERY LOW
PRESSURE!) testing the tanks to ensure that there are no leaks with the
senders installed. Just block up all the holes with a finger (might
require two people), and apply the low pressure to one of them. If the
pressure doesn't stay in the tank, then it is going somewhere indicating a
leak. This simple step could have saved us the work of having to drop the
(now full) tanks again.

I was able to get the 'collar' off by gently tapping the 3 ears that stick
up from the collar. I would tap one of the ears about 3-4 times then do
the next one, then the next one. Came off pretty easily. Installation
was the same in reverse. BE CAREFUL WITH THE SEAL AS IT WHAT TO GET OFF
CENTER AND WILL LEAK LOTS OF GASOLINE ON THE PAVEMENT WHEN YOU FILL UP.
That's how I got so much practice...
