Tom,
I have posted the exploded view of the carb to the Photosite:
http://www.gmcmhphotos.com/photos/showphoto.php?photo=40004
If the threads are stripped at point 1 or 2 the fix is simple, get new
filter housing.
JimK sells them:
http://www.appliedgmc.com/prod.itml/icOid/1014
If the threads are stripped at point 3 you've got a BIG problem! Re-tapping
them isn't an option - they're GONE! As you can see from the photo above on
JimK's website those threads are fine. The reason they're fine is because
the carb body is a "soft" alloy and fine threads can take more torque than
coarse threads.
If they're not gone and just cross threaded I ga-ron-tee that a tap large
enough to re-tap them is going to be EXPENSIVE!
Even if you can re-tap those threads you must also take into consideration
that the filter sees pressurized fuel. I don't know what the mechanical fuel
pump puts out off the top of my head but frankly I, for one, would not like
the idea of having semi-compromised threads retaining the filter housing. If
they begin to leak you've got fuel leaking out on top of a hot manifold! NOT
a good situation.
Before you head down to Potato Lake ;-) you need to confirm EXACTLY what is
stripped.
If the threads at points 1 or 2 are stripped I would recommend that you buy
one of these flexible fuel hoses along with the filter housing from JimK:
http://www.appliedgmc.com/prod.itml/icOid/853
There is no way in hell that I'll make any recommendations as how to fix it
other than to replace the carb if the carb body is stripped.
Good luck!

Sorry guys, I should have mentioned it's a 455. It had just been rebuilt
when I bought the rig. What my mechanic was doing was replacing the hard
line because it had been crimped when the engine was re-installed after the
rebuild. So it could very well be that he had missed a washer in the
installation of the new line and filter, or a mis=alignment of the
connection. I have not been down to where it is since he started on this so
I don't know what he has done exactly.
I'm planning on going down this weekend. Would there be a tapping kit and
flare filter along with the plastic washer that I can buy before I go down?
He is down at lake Pomme de Terre, and I don't think he has immediate
access to tools and parts as I do up in KC. I plan on going down and
working with him myself to get this fixed. Any ideas of what I need to
purchase to get this done?

Ken,
Looks like you made a liar out of me! ;-)
I WOULD trust the repair fitting that you posted if the carb body was
stripped.
I'd still replace the solid line with the flex line from JimK.

My carb was leaking because of triped out threads, the PO
tried R T V and a home made gasket. I took to local rebuilder
and he used a Heli-coil. this fixed mine.

P.S. Alaska in May--you guys heard about that vacation. Then Albany,
Albuquerque, Hartford (and the rest of CT), St. Louis, Atlanta, Las Vegas
(for 11 days). All week-long trips. I've been home for a week. But next week
is Oakland, and then back to Nevada. Back to Alaska in September (for the
work of the taxpayers, this time), and Kentucky. This fall I'm going to try
to keep it down to two trips a month. I have been in my office in Baltimore
4 days since May 19--which is the silver lining on that travel cloud. The
travel is exhausting but I love the work I do when I'm there.
P.P.S. ObligatoryGMCcontent: I will be taking the coach to our annual
bluegrass festival again in September. But I'll be in Alaska during the
International rally.

Update on the carb situation. I talked with the mechanic and suggested useing the repair kit on the connection. He said he has already tried that and it did not seal. So it appears that the repair option is out. I'm getting the impression that there isn't many of these types of carbs sitting on a shelf in the junk yards and that if they were the linkage probrably has seen better days. So now I'm faced with getting a new carb or have Patterson provide a rebuild for me. I understand there is a Edlebrock available for this motorhome. I've always have heard good things about Edlebrock's products. I have a concern about the core condition of the carb I have now. Not sure what condition the housing connection is in, I have requested a picture of that connection to be sent to me.

I would send that carb to Dick Paterson and ler him determin eif it is repairable. Also there is a good carb repair place in Oak Park, Illinois if you are running short on time. You might save a few days mail time with them. I still recommend Dick Paterson first.
I would be shocked if Edlebrock made a GMC specific carb considering that there were only 12,000 GMCs made across 6 years and in that time they had 4 different carbs depending on Federal or California and 455 or 403. That is not much inventory to be making a carb for 30 years later. I just looked at Edlebrock's site and could not find any reference to a GMC specific carb. I may have missed it.
I'll bet anything they are selling you a Toro or other GMC Quadrajet and saying it will also fit your GMC.
If it the filter housing screws in tight then I would apply a sealant to it. I believe that the company that makes thread locker make a version specifically to be used as a sealer with gasoline.
I'll tell you how I would fix it if you can not find any other possible wayway. I would remove the filter and JB weld the housing to the carb. Then I would install an inline filter in the short hose that goes between the fuel pump and the steel line.
Call Dick Paterson.

The reason why people strip the thread there is not realizing that by
undoing the 4 bolts and sliding the carb back about 1/4 " will make
the difference.

Update on carb. I'm getting a picture of the connection to see if it can be repaired by another mechanic who is close by. I am hoping this will be repairable so that I can at least get some use of the motorhome this fall. Then I will get with Patterson this next season for one of his rebuilds along with his distributor setups...only if he promises me that 12 mpg someone said he got after he intalled his stuff. We'll consider that her birthday gift for 2012. Thats my thought on this...I'm just wanting to get some use out of it this season some time.

Tom,
Maybe "someone" will promise you that YOU'LL get 12 mpg but I don't think it
will be Dick.
On second thought maybe Dick will promise that you'll get 12 mpg if YOU
promise not to drive more than 50 mph! ;-)
I can promise you that will have a big smile on your face after you install
one of his carbs and distributors!
