I AM NEW TO THIS SITE BUT HAVE LEARNED ALOT JUST BROWSING.I HAVE A 402 BBC , I AM RUNNING HOLLEY FUEL PUMP [MECHANICAL] THAT IS PUSHING STEADY 8.5 PSI.NOW SHOULD I AD A REGULATOR OR GO BACK TO STOCK PUMP.I HAVE NO RETURN LINE.MY PLUGS ARE GASSED OUT VERY QUICKLY.ANY HELP WOULD APPRECIATED.

thanks for the info.the pump has no place for a return line will this create any problem.if it helps, the motor is in a 72 chevelle pushing 400 hp ballpark figure.is street driven only never at the track.i know this is probably a no brainer for you guys but i am still learning the hard way. thanks again for your response
