Put 1/2" inlet in tank (new) thru unused pluged off fitting. Took 1/2" line to FASS pump out of FASS to new 1/2" steel tubing to front where stock line ends. Converted back to 1/2" hose to injector pump. Took 1/2" barbed fitting and welded to 1/4" fitting to go into injector pump. Drilled out fitting to (I'll never tell) new bigger size. Used old 3/8" supply line for new fuel return line to handle increase fuel flow. Now I can drain my 36 gal tank in 1 minute and 16 seconds.
