Hey all, My dad is having a problem with the fuel pump in his 67 firebird. It's a bg 130gph mechanical pump. He had to change a freeze plug on the engine, and had to jack the engine up a bit. So he took the pump off to do it. It was working great before this. It shot the fuel up much faster than the stock pump he had on before. He bought it used from a very respectable engine shop in our area. The pump will move fuel by hand, but will not do anything while on the car now. He put a stock pump back on just to fire it up and it works fine. Anyone ever had this happen?
