Answer -------from now till doomsday. . It can not be done that way.  Howev=

injection pump. Then run a piece of line from pump to clean container.    T=
he flow in return is determined by pressure in pump (RPM sensitive)  and th=
e size of the orifice in return banjo. So get yourself a Banjo (inlet) from=
 an old pump   and make a bigger orifice. Use ordinary solder to fill exist=
ing hole. Make orifice with a  needle. Leaving it wide open will starve the=
 high pressure piston.

Then just dump the CLEAN fuel back in tank.     Now how FAST can it be done=
 ???   that depends on size of orifice and speed of pump . Would expect it =
to be    a matter of minutes.              Hagar.

PS: Return from injectors normally is insignificant. Run them to a clean co=
ffee can.
