Reading the post “Repairs 101 Sect. 1 “, who would ever have guessed that my stalling problems were actually caused by a fuel filter that was supposed to be the proper replacement part ?
Somewhere along in the history of this vehicle, something was changed. Probably the type and design of the original carburetor, because the tube sticking out from the photo is a return-to-the-gas tank connection. I had it routed to the steel return line attached to the chassis, and it was just as I remembered it had been on my earlier Dodge Ram van. The carburetor on my RV is not one that has a return feature.
Problem solved! I realized that the engine was calling for way more fuel than was entering the carburetor, since a good volume of gas was going BACKWARDS to the gas tank – in situations such as climbing hills; accelerating to join merging traffic; passing vehicles to quickly get back in line and climbing slow but sustained rises (like the Continental Divide!).
The minute I blocked this return line, and provided the engine with all the petrol it needed to function the way it wanted, my difficulties vanished. I’ve never been bothered since.
You get “T” for trying.
