A failing pump motor will show 40PSI or less when tested and most often randomly pop the 10A fuse. A healthy pump motor only draws approx 60 watts and when the motor is failing the draw will be in excess of 125 watts, or more, popping the fuse.
Ref your twist-and-go TPS reset remark...must be a 2008-2009 model. Very easy to properly rebuild with the correct parts. If 2010 model, quite a bit more difficult.
I would:
Remove and clean frame sump
Strip down pump assembly and replace only the high pressure feed line---5 O-rings----fuel sensor---high pressure filter---suction intake sock filter----high pressure filter bushings. Pump motor probably fine. They rarely wear out.
