I'm thinking the fuel rail is the way to go. 4 injector clips that have to come off anyway, one vacuum line at the end, and two bolts holding it to the head (I think). I'll leave it with the car & drop the old engine out from under it, and put it onto the 'new' (or rebult?) engine. > The same type of fuel line connectors are used on other GM cars, e.g. > for the fuel filter on recent Opel/Vauxhall/Saab vehicles.

May I use your description on the page I'm building (with name credit if you want)? Dave
