The hoses above the tanks include the fuel pick up for the fuel pump. If it is now10 years old it is probably not a barrier hose (which is resistant to the ethanol in the gasoline). It could have cracks that don't leak gasoline but could allow the fuel pump to suck in air through the cracks. This can give you the power loss problems you have alluded to.

You should replace all of those hoses with barrier hose or you can put in metal lines instead of the rubber ones.

Maybe I don't understand the answer... These problems showed their ugly head when the fuel lines were replaced in 2007 so the hoses were new.
I was new to the coach and they replaced the carb, messed with the distributor, la, dee dah. Ran ok for about 20 miles then troubles began again.
It's a long sorry story, replaced most everything on the engine including 4 carbs, manifold, 3 fuel pumps (one rusted out internally and was only 3 years old. This is what destroyed carb #3).

I am considering replacing the hoses above the tanks with metal if I can get a good permanent seal to the tanks. Don't know how to do that yet but i am still studying all this.

The hose I ran from the fuel solenoid valve to the motor mechanical pump is supposed to be the latest ethynol resistant hose. My original thoughts were to run up to the metal line that crosses the cross member but just bypassed that metal pipe because some told me that the metal pipe could be plugged. Any idea why they used metal in that area of the engine compartment???????

I have not found any cracks on any of the hose that I have inspected/replaced so far but my mechanic says that doesn't mean there isn't a problem where I have not been able to visually check it yet. He is betting there is a problem above the tanks, thinking a pinched hose. And when I think about it, that can easily fit into the scheme of the problem. I just can't get to it.

Like I posted before, I talked to the GMC dealer and they quoted $3,000 to drop the tanks and replace the hoses. I more or less told them "WHEN PIGS FLY"...

They kept saying they had a GMC in before and they had no problem with the money, so I know where they are coming from. They don't have a rack to lift a GMC motorhome anyway, would have to do it all manually. SO THEY ARE OUT!!!!

There is a fellow South of me that I am told could do the job but his life is changing a bit so I don't know how willing he'd be wanting to help out. But If I can get him on the phone, we'll see what can be worked out.

Meanwhile, I am taking a very close look at Jons RAMPS because it is very possible that I will have to do this myself and I can guarantee its gonna take longer than a week as I am learning as I go from this point...

I've given up hope that the limitation is bad gas as the gas is all fresh, I've gone over the hose, replaced most of it and found no kinks. It is pretty much a sure thing where the problem is.

But as I say, this has been a good thing, I am up to 55 MPH... Very Happy

From sitting in the driveway dead, that is a big push forward.
I installed some unique COB valance lights, have the parking brakes cabled up and found a way to secure the drawers and doors so they won't fly open while traveling... So it seems we are now on an up-swing. Very Happy

AND WE CAN NOW GO 55 MPH!!!! Its a good day!
