First, I am most appreciative to all of you that have offered ideas to find this 10 year long search. I know how long it has been because that is when I bought the tires and aluminumum wheels and had the fuel lines replaced, which of course required dropping the fuel tanks.

The power loss problem has persisted since, all this time as we searched, repaired, replaced and continued to test. I am thankful that I have at least been able to start the GMC so it isn't really a forgotten derelict. I always shutter when I hear stories about those GMC motorhomes. As my mechanic likes to repeat, vehicles do not get better sitting and rusting.

So most of all of the accessories and some engine parts are new. Parts of the fuel line from the solenoid, to and including the Mechanical fuel pump are all new. Running the test connected to the normal fuel system, the power loss at 45mph is there.

We finally made an effort to use the external gas can. This can be involved also now that the mechanical fuel pump has a return fuel line. unless that return line feeds to the external gas can, you won't have a very long run time.

Testing with the external fuel can was SUCCESSFUL!! I took her down the highway on 3 different occasions doing 75mph and she still wanted to go faster. The problem has to be the lines to the tanks. The Fuel tanks have to be dropped to get to them.

So....... what is the cost to drop a GMC motorhome fuel tanks??? I don't know yet. I am still excited that we found the cause.

The Additional good, or somewhat good news, is the motorhome can now be mobile. It can be driven to a shop. More THUMBS UP there.!!!!

HOWEVER:

I drove over the the local GMC DEALER to see what they would do for me.
The first hint was his snicker when I told him I had a GMC Motorhome.
He sort of took a step back when I told him I needed the fuel tanks dropped and the fuel lines replaced.
When I pressed for an estimate, he said it would cost me $3000.00. Yes that was THREE THOUSAND DOLLARS.

I considered dropping the tanks myself but I don't have the racks nor the storage for the 3/4 full amount of gas that the motorhome is holding in the fuel tanks.

I glanced around the shop and noticed that they do not have any racks to lift a vehicle like mine and they would have to raise it manually.
The obvious answer is they do not want to take on the job, and if they do, they plan to make me pay for it.

We've come so far and now I will be looking to see who can drop the tanks and change out the fuel lines. I will be more into it in the Spring but am checking out possible places and pricing them out.

So if you listen to that dealer, that is what it costs to drop two GMC Motorhome fuel tanks... SHEEESH!

So I continue onward with this fiasco. Always open for any ideas.

Thanks to all............
