Hey, So Last year i replaced my stock fuel pump on my chevy 454 in my baja. I put on a holley 130 gph pump. Ran good for the rest of the year. About a week ago the fuel pressure gauge drops down to 0. I took off the line, no fuel would come out when i cranked her over. SOOO i put a new fuel pump in. The same fuel pump, holley. I used it for a total of 4 hours and now i lost fuel pressure again!!! I don't know what it could be. I'm totally clueless. Any advice would be greatly appreciated.
