HI all, been awhile.... Mike from Madison, WI here.
I have little problem. GMC parked but we like to drive to TX Saturday for a
college visit with my 16 yr old. anyways right side has like bottomed out.
we tried raising it but seems pump is not raising it. not sure why.
so what can we do??? someday I should buy those special values you all have
I think. can inflate with a air compressor then.
is my air bag bad? how can I test? for now I jstu liek it rasied so we can
travel no need to raise or lower it once it is up. can I use floor jack I
have? Can I place a block of wood in it to hold it up?
appreciate all help and advices hope we can get it going.
it is 25 degrees here it that matters? I can go take pictures if you like.
Maybe local buddy Tom can assist me. I try to call him.
I do have old bag from previous owner not sure if it is good or not.
thanks
Mike

What? You don't have air valves? You can jack the coach up
and the arms will drop and the bag will extend. Remove air bag
and put in 17 inch 3/4 all thread with 1 in steel pipe over the center
section. use large washers and nuts on both ends of all thread
to hold it in place. This will work for short trips. I don't recommend
for long trip to TX. You might get the load off the bag by jacking
up the coach. Remove the air lines from the end of the air bag a
replace the line fitting with a Sharder(sp) valve from your local Auto
parts store. You will probably need an adapter fitting so the
Shrader(sp) valve will fit the bag. Once you have a shradder valve
on the bag you can air it up from an air tank just like a tire.

Mike,
To help you we need to know what year GMC you have and what kind of rear
suspension system you have.
Power Level
Electro Level I
Electro Level II
The 1975 & 1976 Maintenance Manual X-7525 has REAR SUSPENSION TROUBLE
DIAGNOSIS CHART in Section 4 pages 4-5 & 4-6? This is for the Power Level
System.
1976 Maintenance Manual Supplement has a Trouble Diagnosis chart on pages
4-11 to 4-14 for the Electrolevel I system.
1977 & 1978 Maintenance Manual Supplement has a Trouble Diagnosis chart on
pages 4B-13 through 4B-15 for the Electrolevel II.

HI all, just got home from shopping.
1978 GMC Electro II pretty sure.
I will see if right side raises tommorow.
then I will do as you all say here, get that valve etc...
then I will get that special delux valve that many have can use pump or
external air I recall, forgot who on GMC makes or sells these delux ones.
I keep you all posted tommorow.
thanks, Daughter be happy we can get it going!

thx
Mike

Ace hardware has the schrader valves. They are about $2.50. Look in the area where the brass fittings are. The have the correct diameter one so the brass adapter shown in the previous posting will not be needed. Just unscrew the line going into the bag and screw it the Schrader. Air up the bag with what ever you have or borrow a portable air tank if you do not have a compressor. If you need a bag in an emergency or a temporary loaner let me know. My spares are all out on loan but there is suppose to be one near me that another GMCer was to deliver to me months ago. I'll call him and verify he has it if you need one.

Byron Maxwell of Boerne, TX 830-816-3004 sells a really nice
set of air bag valves with aircraft quality shutoff and Schrader valves.
Really reasonable if you consider you don't need to spend the day
looking for them and I don't think you can beat the quality.

The schraeder valve's the way to go for now, but in the long run it sounds like your RH compressor may not be running. When you get that far, let's see if we can help diagnose the issue. The EL II is actually a very simple system and the cause should be easy to find. Have you tried to see if it levels in auto mode or in manual mode?

When I talked to Byron about 2 years ago seeking information about the
old Todd converters and transfer Switches, he was having health
problems. His website no longer works. By all means call him, but I
don't think he is selling direct anymore. Jim K appears to be
selling the kits now. For Information only - The old Todd engineers
that left Todd and started there own company called IOTA Eng. and put
the quality back into the products as per Byron. See links below.

If you have the Electro Level II, More than likely the one compressor
is not performing.
There are 2, one for each side.
We do have the valve kit in stock. You can waste lot of time trying to
round up all the parts to come up with a workable unit.

Well daughter and I went and left side raised, then we tried right and
surprisingly enough it raised also! lucky us. whew... we can travel Sat
now...
1. it has always slowly lowered. I had a lose wire inside but I think most
be a slow leak on left side somehow. I will by those nice valves I saw
posted link to here. thanks
I did by that schraeder valve though to have with me just in case.
2. My information on BlackList is old. Who DO I email to get that properly
updated.
we plan to leave Sat or probably Sunday am from Madison, WI and head to
Houston TX fyi. maybe we see some of you all along way. or be glad to call
as we pass your cities.
I will have iPhone and new macbook with us also. be fun easy trip to View
College, and she wants to by great priced used SUV somehow. lol. anyone
have a good one at good price.???
thanks all again. I love this group and hope to get more active with it
soon. LOL I need a female partner to enjoy my GMC with! 
thanks again, Merry Christmas to all.

MIke,
Take that schrader valve (or two) with you on your trip. Also get a cheap small 12 volt tire inflator / compressor capable of 150 PSI or more. If you have a slow leak along the way, those two items ought solve your problem until you get back. You can get a compressor most anywhere - Sears, Harbor freight, Wally World, and probably Menards, Lowes and Home Depot.
