Hi all, I have just installed my Clevo and FMX into my XF Ghia. I am now looking to sort the fuel system so that I may maximise the fun factor. I currently have a Holley Blue pump and 1/2' fuel line running to the engine bay. This is accompanied by the standard Holley fuel regualtor. The engine is a very stout 351 cleveland with 302 rods, Roller cammed with professionally flowed 2v heads to be run in conjunction with a 4500rpm stall. I have a Barry Grant RS series carb with annular boosters which is configured to 810cfm. will be running a 4500 rpm stall. So now the questions begin: 1. What fuel regulator should I use? 2. Should I get one that utilises a return line? 3. What size should the return line be? 4. What setup should I use at the carb? Eg: fuel log or one of the braided -8 jobs off ebay? 5. If the fuleog idea is no good, what should the lines size be to ensure that there is minimal restriction? 6. Should this have a dual inlet to ensure that bother metering blocks get equal pressure? Or is one sufficient? I look forward to hearing from you. Your advice is greatly appreciated. Brad
