I just destroyed my original savage 21 fuel tank, smashed the primer straight through the bottom of the tank. I'm looking at replacing it with a rear pick up tank from the Savage 25/ss/X. I don't have rotostart however so i'll still need to prime the engine before i try to start it, plus i need to have some way of priming my header tank as well. Can i just get the 25/ss/X tank and use the Associated Fuel Primer bulb that you can get from Tower (http://www2.towerhobbies.com/cgi-bin...?&I=LXFUD3&P=7) between the main tank and the header to prime the header/engine?
