Anyway welcome Nigel. To test your fuel pump, disconnect the larger fuel delivery pipe and the carburetor. (smaller one is return to tank on a loop system). With the pipe emptying (CAREFULLY) into a container it should deliver fuel at a rate of 1.1 litres a minute. Also with this pipe plugged into a pressure guage it should deliver about 4 bar.

Above the fuel pump, attached in the rear wheel arch of the body, is a check valve in the return line, though I\'ve never known these to fail.

That leaves the pump itself, the filter, which you\'ve changed, clogged lines or stuck needle valve (gummed up??) in the carb.

Good luck. David.
