Oil Tank piping help

I'm having an underground oil storage tank removed and replaced with an above ground tank.  The new tank will be located in the basement no more than 15' from a boiler with a Carlin 100CRD burner equipped with a suntec single stage pump.  It is currently set up with supply and return piping.



My question.  What is considered the optimum set up for fuel oil piping on a tank in the basement?



An oil  delivery man mention going back with supply and return with a check valve on the supply through a duplex tank bushing from the top of the tank.   Another tank guy mentioned using a single supply from the bottom of the tank.  The new tank will be 275 gal.



A Suntec technical document stated that a single pipe is recommended, with no check valves, due to lower inlet line flow.



What is considered the accepted safe set up for oil supply piping for a tank on the same level as the boiler?



Thanks for any thoughts.

S.

    2 pipe

    is not needed, and rarely is. If the system is now 2 pipe, make sure someone removes the bypass plug, and plugs off that port, ant there should never be any valve of any sort in a return line. At the pump or tank. The system will gravity feed the unit
