So last year, my 83 454 decided to crap out on me while driving in 95°f ish weather.
Thankfully we didn't reach the really steep grades yet and we were able to limp the rig back home @ 35mph.................
Carb had no fuel in it when it died. Couldn't hear the electric chaser pump pumping so it either over heated or was fully primed. Waited a few minutes and it started, made it half a mile and died again. Turned around and coasted back home.
In the near future, when it's not 117-120°f outside, I'm going to put a Carter 4070 After the dual tank switch valve
From the looks of things, my return line from the mechanical pump is kinked half way down the frame rail, that will be the first thing replaced. I bought a new mechanical pump as well. Lastly, I'm going to put the fuel pump on its own circuit to know it's getting a true solid 12v. Unless I should run a solid circuit AAANNNDDD put a ballast resistor in there???
The one thing I can't decide on is adding a fuel cooler that sits in front the radiator or add a filter with a bypass outlet right in front of the carb. I'm leaning towards the splitter because it seems most efficient to recycle the fuel than to just hope you cool it down enough. Everyone claims the vapor lock starts in the mechanical pump, so I feel cycling fuel is the best way to remedy this
Anyone have suggestions on anything? I'm open ears to things known to fix these issues.
We got the RV from family who only used it during winter months for camping. They never had vapor issues but they only used it when it was 50°f or cooler outside.
