New dual HS carbs installed but stock AC delco pump seems to feed too much fuel. Should a regulator or SU pump be used? What pressure should I have to to the carbs?
""""""Should a regulator or SU pump be used? """"""
Absolutely. You want 2.5 to 3 psi pressure....split the difference. A regulator will smooth out the fool flow and help the carburetors. the small Holley reg with the low pressure spring is economical and cheap too. Its all in the archives.....<))).
