the roundy cars i'm refering to is the wissota late models and mods. the fuel pump is belt drive on the front of the engine, just like an alt. some of the tanks are mounted low, others high. also, are all belt pumps "pushers" or is there a way to tell if they suck the fuel. asking these ? as i don't want my friends engine to run bad from lack of fuel. also need to know to defend the reasoning to the guys at the shop where he is building the car. these guys have been racing wissota classes in huron,sd for quite a few years using this type of fuel system. and i don't think they are the only ones.
