What was the final consenses on the gasket thickness,was at diesel injection in Louisville yesterday and they couldn't just get the washers ,acted like they were lost ,didn't know if they were 7mm or 9mm and then brought out some real thick ones just said no thanks,I thought that they are ID 7mm thickness 2mm . For a injection shop it was easy to see that they haven't tried anything accept off the shelf parts from the major name brand suppliers boy are they missing out.
