Fuel pressure drop

Jrayecu 24.06.2014, 02:32
I have a blow through setup on my 347 fox and when my fuel pressure comes up to 15# the pressure suddenly drops to zero and takes a few seconds for the pump to build pressure again . The fuel system is ;pump is an a2000 , aeromotive boost reference regulator, -10 feed and return lines, fuel cell, Csu bt carb just got back from Kevin.
Any ideas ? Pump is wired to a relay with 10 gauge wire right at the pump

I think it may actually be the relay shutting down . Trying to find a higher amp relay
