Hello some help would be appreciated and please forgive my lack of knowledge on the lister engine in my old dumper. Due to my lack of experience i have managed to crush the pipe which exits the valave cover and returns to the top of the fuel tank, would anyone know  what this is called and where would i get a replacement. many thanks

tried all your suggestions still no luck

thankyou for letting me join, I have a problem with my dumper engine, during the last heavy rain the cover blew off and water penetrated the air filter, having tried my best to drain it and dry it out since then i have been unable to start it . I drained the oil and put in new drained the fuel and same, with my limited knowledge i checked the delivery pipe to the injector and there seems to be no diesel spurting out, does this lead to a fuel pump problem or have i missed something i would be grateful of any help thanks
