Re: older gulfstream 1987 sun vista
Hi Steve,
I had the same problem with another brand rv, and yes, I changed the fuel filter, but I also insulated the entire fuel line under the coach. A lot of the older models(at least that I have owned) sometimes have a problem with vapor lock from the fuel lines becoming too hot under the coach. Just a suggestion. Mine would run great, then act starved for fuel, and die. After insulating the fuel line, no more problems.
