Lewis25 Posted February 9, 2014 Share Posted February 9, 2014 Hi there, I have a disco v8 engine which is currently going into my series 2a. It will only run when the return pipe is pinched. There is an electric fuel pump which ticks away when it is not pinched but then when i pinch the return line the ticks become slower, (more pressure) and it will run nicely. Any ideas of a more permanent solution to this? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
