Fuel from rear tank

[HO455]

After sitting and before trying to start the engine look down the primaries and wing the throttle watching for fuel being pumped in by the accelerator pump. No fuel shot could indicated no fuel or a bad accelerator pump (or possibly the check ball isn't seating). Then crack the fuel fitting at the inlet to the pump and see if fuel runs out. If not then your problem is in the line or the pump diaphragm. If you have fuel at the inlet then try the outlet. If no fuel then I would look at the fuel pump. If you have fuel at the outlet then I would say your float bowl is leaking. This is a common problem with Q-Jets but I don't know about Edlebrocks. But remember that it is perfectly normal for the fuel to evaporate out of the bowl in hot weather in just a couple of days. That is one of the reasons carbs have disappeared from new cars is that that evaporation counts against emission results in the eyes of the EPA.
