I have just had my mk2 diso fail its Mot on a fuel leak which looked like the fuel reg gasket, so ordered and fitted new one but it's still leaking added a second gasket to try an stop it but still got a leak, doesn't seem to seal properly has any one had a similar problem
 
Are you sure it's the gasket and not the pressure reg itself. that's what usually goes. Bosch make.

I have had a complete reg replaced with new gaskets, but it did not seem to fit the completely flush, so the gasket still ****ed out fuel, so made another gasket to fit with the original gasket but still leaked, so my mechanic is trying to use a gasket seal to see if that works
