My Motorhome is Bogging Down on Acceleration
1984 E350 Ford with 460 and Carburated Tioga Camper bogging down when you step on gas. It did have a dirty gas filter but it has been replaced the one on the rail should I replace the one in the carb? It was running fine last year.

ANSWER: Hi Cappy thanks for submitting your question on our Ask An RV Question Page
I am afraid that I do not have an exact answer for you, but based on your description I am going to assume that the bogging down is being caused by a lack of fuel so I can give you some ideas on where to start looking.
Since you state that you have replaced a blocked in-line fuel filter I would urge you to check the fuel filter on the Carburetor itself and also check for any additional in-line fuel filters.
A weak or failing fuel pump can cause a lack of fuel to the carb. A kinked or leaking fuel line can also restrict the flow of fuel to the carb.
Another area to consider since you have found dirt in the fuel filter is that there may be rust or other debris floating around in your fuel tank that are partially obstructing the fuel pickup in the tank.Carburetor:
A bad accelerator pump, a bad power valve or stuck float in the Carburetor can cause the bogging down you are experiencing. In some case the carburetor may have to be rebuilt or replaced to correct the problem.
I hope this helps.
