Fuel tank leaking

[462loadtoad]

I have been a long time lurker and have recently acquired a 71 blazer. I have been replacing items not to restore but to make it an all around good daily driver. Recently the fuel tank has started leaking from what appears to be the top. I need to pull it but I am not sure about the bolts pictured. If I remove these bolts will the fuel drain from the bolt holes or are the bolts running through a sleeve? Or should I just scrap this tank?

First of all.. Welcome to the forum!!
That is an aftermarket tank. (your leak is more than likely the gasket on the sending unit) those are carriage bolts that run through a sleeve in the tank and up through the floor.
That little round "puck" you see on the bottom is actually a nut and not available from anywhere I have found.(you need to try and save these!!)
I would go inside the Blazer and locate the tops of the carriage bolts (you should see round heads with oval washers) and either grind the heads off or drill the heads off, then the tank will pretty much just fall out. (be sure to unhook the sending unit wire and fuel line).
