Hi, you will need to pump it out. It is best if you can pump it from the fuel rail, so that only a minimal amount would get into the injectors. You can do this by removing the fuel return hose from the fuel pressure regulator and attaching a hose that you will lead to a bucket. With the hose in the bucket, turn the key on so the fuel pump runs. If the fuel pump will not stay on, please get back to me, and I will provide a relay bypass procedure toi keep the pump running. With the pump running, the diesel should come out the return port into the bucket. If it comes out too slowly, try pulling a vacuum on the vacuum hose that's attached to the regulator. You can use your mouth to pull the vacuum if you attach a clean hose. Once you have all of the diesel out, put in some petrol and pump a couple liters of that through as well. Then reconnect the hoses, and the car should start OK. Please let me know if you have questions.
