What's the best/proper way to clean the fuel system on a 262C with the B27? I've dropped the tank and have replaced a rusty sending unit with a new one with a new sock filter and used the POR-15 fuel tank restore kit to take care of the gunk and rust in the tank. I've replaced the underhood fuel filter too. How do you clean the rest of the system? When I push down on the throttle plate and look inside the intake manifold there is a lot of oily residue all over the inside of the manifold. Is the Run-Rite System a good candidate for cleaning the injectors?

BG44k is about the best run-thru-the-system stuff out there,and it's pricey to boot (like $25+ per bottle). Good to change your plugs afterwards. Other than that, Techron (about $7 a bottle, and available in more places) is pretty good, perhaps not as aggressive at the BG44k.
