I have an edelbrock RPM fuel pump feeding a RobbMC Powersurge fuel cell. About a year ago my Earl's rubber fuel inlet hose along the chassis basically dissolved and cracked so I replaced with stainless straight line and PTFE braided line. The engine didnt start and i noticed the fuel pressure was down to 2 psi. I initially thought it was the electrical pump or the circuit. All has checked out ok but as i replaced the electric pump i noticed a large amount of black goo on the pump sock and on the bottom of the surge tank, also there was no fuel from the mechanical pump.

Can the pump be serviced or flushed put or do i need to just get a new one?
