I NEED HELP I AM CONVERTING MY FUEL INJECTION TO CARB. I WAS WONDERING HOW I SHOULD CHANGE MY FUEL PRESSURE. SHOULD I TAKE THE TPI FUEL LINES OUT AND PUT 1 FUEL LINE AND DROP IT INTO THE GAS TANK AND USE THE MANUAL FUEL PUMP, OR SHOULD I BLOCK THE RETURN FUEL LINE KEEP THE EXISTING ELECTRIC FUEL PUMP AND BUY A FUEL PRESSURE REGULATOR TO BRING THE FUEL PRESSURE DOWN TO 5 LBS. PLEASE HELP. I NEED THE CHEAPEST EASIEST WAY TO CHANGE THE FUEL PRESSURE.
THANKS,
BOB

 

do it either way. If I could do it all over again I would put a 1/2" new line all the way up to carb and put a real electric pump inline along the way. I would not depend on that stock electric pump for squat. Chances are it will fail.
