The system works well but can be susceptible to dirt, very much like the optical electronic ignitions from Luminition in the past.<br>It amazes me that you have had so little success with the SU fuel pumps. If rebuild following the instructions to the letter you will have a pump that lasts for ever but you do have to operate the pump/drive the car regularly and also make sure the pump is fitted correctly:horizontal and the outlet on top!!<br><br>Cheers,<br>Kees Oudesluijs<br></body></html>
