can any one point me in the right directionon this. I recently bought an 87 gn that set for a year. it is all stock (from what i can tell) exceptfor the 3" cat i just had cut in & a sick sounding electric fuel pump. the pump is an in line pump and is mounted rightout side the tank. What would be a good replacement for it? ANd what is the adverage stock quarter mile slip look like on these cars?
