Roger, I wanted to address your comment regarding fuel line replacement. If I'm reading correctly, you ran new hose from the fuel tank to the firewall. Does this mean that you inserted the fuel line into the plastic teat that is bolted to the firewall? I'm assuming you know that you need to eliminate this teat and go with new hose all the way to the injectors, then out to the fuel regulator, then out of the regulator, at least to the other side of the firewall. Old fuel hose and the plastic teat (both perilously residing inside your engine compartment) were your main threat and still are. Miguel

I have not failed. I've just found 10,000 ways that won't work. - Thomas A. Edison
