Fuel pump fitting size 1970 L78 stock fuel pump
I added a one inch open spacer under the stock 4492 Holley for my 1970 Nova with L78 and stock AC delco fuel pump and wanted to purchase a fuel line kit from the stock pump to the carb to replace the metal line that is now to short.The sales rep at Summit racing is asking we the inlet thread size for the stock AC delco pump.From what I can measure it looks like either a 5/8 or 9/16.Does anyone on the site know for sure.Thks Bob
