Fuel pump question

1 1/2 to 4 lbs only pressure. split the difference.
 
""""""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.....:smile:<))).
