The Engine In My Motorhome Starves Itself Of Fuel.
by Jim Smith
(West Union Illinois USA)
I replaced the fuel pump, fuel filter, rubber fuel hoses and ECM control module in my 1983 Ford Tioga 27' motorhome. It has a 460 engine in it and still starves itself for fuel especially on inclines (hills).
I have also removed the fuel tank and checked connections for leaks but found nothing. Sometimes when you shut it off and restart it going down the road during one of its' "fits", it will come out of it for awhile and run OK. This is starting to drive me silly. Any info will be greatly appreciated.
ANSWER: Hi Jim thanks for submitting your question on our Ask An RV Question Page.
It sure sounds like you have done a lot of work on your Motorhome to solve this problem. Based on the information that you have provided me there is one thing that you have not mentioned looking at and that is the carburetor. All of the problems you have described can be caused by the carburetor.
If this motorhome has been sitting for any great length of time in the past the inside of carb could be lacquered up causing the problems you described. The stalling while climbing could be caused by sticky floats not allowing the fuel bowl in the carb to fill up properly, problems with the accelerator pump in the carb could also cause some of the problems you are experiencing.
I strongly suggest that you pull the Carburetor off and inspect it and get it rebuilt or if you are comfortable you can rebuild it yourself.
Hope this helps.
