The fuel pump on my '59 Galaxie 292 cu in will no longer pump fuel. This is the double one that also operates the wipers. After searching the archives here it's apparent there are no rebuild kits available and the made in China ones are junk. Some have used an electric pump to push fuel to the engine. I ordered a Carter P4070 low pressure pump which was suggested. My question is can I leave the old pump in place to run the wipers and push fuel through the pump or bypass the old pump and go straight to the carb?
