If the fuel overflowing [through the rear bowl vent tube] just occurred after the fuel pump change, the first thing I'd look for was the rear bowl fuel inlet needle seat being "held" open by a particle of dirt or crud released by the action of handling the old fuel line. This sometimes happens as such dirt particles, i.e., rust, rubber tubing, gaskets, etc., can keep the carb bowl needle from shutting off the constant fuel flow from the pump whenever the engine is running. Then, all of the excess fuel has no where else to go except to "escape" through the bowl vent tube & into your engine, which then usually stalls from the excessively rich mixture.
Holley carbs can be easily fixed - since they are of modular design. Just remove the rear fuel bowl needle & seat assembly, and inspect for debris. You or your mechanic can easily perform this operation with basic hand tools...good luck! |
