Fuel system issues

I,Mark Etheridge do not mind Ed posting my name.I ran that pump tru a regulator at about 5.5lbs.and ran a 11.43 with my slant,no fuel starvation.I agree with most of you,its not fuel starvation related.I dont think bigger rails will change a thing.Float level possible????I lean more towards ignition issues.Just my thoughts.And the only reason I changed out pump is cause I am going to spray my car,60 shot, to try for 4 more slant records.Mark Etheridge
