I have a 2000 Southwind on the F53 platform with a V10, when I tried to start it today the engine turned over but would not stay idling, I tried a couple times and it did the samething. This happened ...
In my opinion fuel additives or air filters or fuel filters have little if nothing to do with OP problems;; also I don't think adding a electric fuel pump on top of/to a High Fuel pressure closed rail system multi port fuel injection system will be a feasible option
