|'81 Winnebago Brave Gas problem||Bill||8-19-02|
|I just bought an '81 Brave. I believe it has a 440. I see that the gas lines have been redone, and a new fuel pump has been installed. My problem is that on my way back from Florida, the coach didn't seem to get gas during the hot part of the day. It would get gas for a few seconds and then I would have to back off and wait a few more seconds before it would run for a few more. It ran real well at night, so I figure that it has to be the pressure in the gas tank. When I got it home, I noticed that there was gas leaking from one of the vapor canisters. This I have yet to figure out. I also haven't figured out the REAL cause of it not running when it is hot outside.|

|Have you checked fuel filters? There may be more than one filter. You should check fuel pressure also. Other than the engine driven pump, there usually is an electric pump, either externally or in the fuel tank. When these pumps fail the engine starves for fuel. Check for dirty filters or another pump first before you go any further.|

|Hi--Sounds as if you are experiencing|
mild vapor lock. Check the location of the fuel lines. Keep away from heat sources (exhaust pipes etc.). You may wrap the fuel lines with some type of insulation. Heavy duty aluminum foil
(kitchen grade) will work in a pinch. The insulation may be secured with plasic zip ties. This insulation is necessary only through the engine compartment. Vapor lock is a condition caused by the fuel lines being heated to the point the fuel in the lines vaporizes. Thae carb or fuel injectors will accept only liquid fuel. At least you can try it on the cheap!
