Hi I have a 1985 GN and of coarse I'm having problems with fuel pressure not going lower than 50 psi after scan master upgrades. Looking for step by step braided fuel line return line replacement. I've read a few but wondering if it's the same as the 1987 GN. I read on which is http://buickturboregal.com/install-6-braided-return-line-buick-grand-national.html. After I install the -6 braided line under the fuel regulator what happens to the fuel filter line?? Confused....Still reading other threads Please Help....Thanks
