Here is my setup for thermoquad carb. Fuel line is 5/16 inch brake line tubing bent by hand using cheap tubing bender.
The fuel filter is back by the gas tank between tank and electric fuel pump. The electric pump is behind the rear seat back on LH side just above the factory mount location for exhaust hanger. The electric pump is to prime the system, otherwise fuel is drawn and pumped by the mechanical pump with elec pump as a back up.
