On my small block, I am using the Carter Strip Super Mechanical fuel pump: http://www.summitracing.com/parts/crt-m6270/overview/make/dodge Currently the fuel pressure is too high at around 11-12 PSI, pushing fuel past the needle and seat on the carb, sometimes flooding it out. I'm thinking I should use a dead head style regulator to cure this problem..what are your thoughts, and what do you recommend for a regulator? I don't wanna have to plumb a return line system. This is for a street car. Thank you. 408 Stroker 533 HP 520 FT LBS...........................1970 Dart RMS AlterKation

There is a lever, a diaphragm and a spring behind the diaphragm, and two one-way valves. The SPRING pushes the fuel into the engine. When some of the fuel has been pushed into the carb by the spring, the lever gets close enough to the cam that it activates, it pulls back on the diaphragm, drawing fuel into the pump. So it won't hurt to have a pressure regulator between the stock mechamical pump and the carb. R.
