If he can get it lower and be consistant I would love to know how. For a carb setup you want all volume not pressure. Look at the difference between the carb pump and the EFI pump the carb pump has up to a 1/2" outlet where a EFI pump has a 5/16" - possibly a 3/8" outlet.The return line probably will not beable to handle that much volume of return and if it does it won't handle it very long. The pressure variance between the lines could be larger than 10 pounds. Bottom line is, it will not be reliable and can possibly destroy the carb. If he gets too much pressure it will destroy the carb..02P.S...If I came across the wrong way, I apologize. My intentions were not to mean etc. Maybe I should have worded things different, I am not here to be a d1ck so if I came across wrong..I am sorry.-Rob</blockquote>
