Although I have not yet replaced my Burb tank, I have replaced the tank in my Blazer with a stock aftermarket steel tank which is sold by various reproduction vendors. I bought mine new from someone who never used it so I can't tell you the brand. The 21 gal. tanks that are sold for the 67-72 Burbs are the same as for the 69-72 Blazers. They come with just a fill tube stub that sticks out straight at about 45 degrees upward which doesn't work for connecting to your fill tube hose on a Blazer so in that application you would need to use the fill neck from an original tank or fabricate one that can either be braised/soldered to the tank or double clamped with a piece of gasoline fill hose. I assume that you may have to do something similar on a Burb install - perhaps someone else who has done it in a Burb will chime in. In any event, replace the sending unit while the tank is down and make sure it is well grounded to the frame.
