So I recently bought an Indy 400. I have hooked up all tubing and I put oil and bled the oil pump. I put in coolant and propped up the front end to try and burp it. I was gonna start it to burp it some more to get rid of air bubbles but I'm not getting fuel. I checked the tank to make sure the tube in the inside was intact and it is. Fuel won't even make it to the shut off valve. I even syphoned the fuel to the end of the tube right before the shut off valve and it didn't pull any. My guess is maybe the fuel pump. But I'm not sure how the electrical works on this older machine. How does the fuel pump even function without the battery? I would love some insight and help. The guy I got it from got it running by spraying some stuff into the carb and it ran and stayed running for awhile. I also have not cleaned the carbs. I don't know if that has something to do with it either. I'm just trying to avoid buying a new fuel pump unless I absolutely have to.
