Vitamin Pepsi Posted May 2, 2013 Report Share Posted May 2, 2013 Howdy howdy. I have a Z with harley motorcycle carbs. They've worked great for the last two years, but this year I tried starting it up in the coldcold minnesota winter and my inline fuel pressure regulator blew up. I replaced it with the exact same kind and set the pressure to 1lb of fuel. But now fuel is pouring out of both carbs like they're both getting way too much fuel. How can 1 lb be causing them both to overflow? I have a fuel return line for unused fuel that doesnt seem to be clogged. Don't know what to do at this point. Any suggestions? Quote Link to comment
datzenmike Posted May 2, 2013 Report Share Posted May 2, 2013 I wouldn't doubt the regulator blew up. You have a high pressure EFI fuel pump in it. Last thing changed... first thing checked. The regulator is not working properly like the last one. or.... Floats are gummed up from sitting and are stuck, not shutting the needle valves. (well assuming HD carbs have float chambers) Quote Link to comment
