fuel lines i took mine to a local hose shop and gave him the new fuel fittings that go on the rail and the old fittings that screwed into the throttle body so i wouldnt have to alter my lines. im sure there is another way to do it.
the temp and oil adapter i got from street and performance just look them up online and give them a call and what ur wanting ect they will know exactly what ur talking about. the water temp fitting will go on the back passenger side head, there is a plug screwed in the head and you remove it to put the adapter in.
look at this guys build, same swap ur looking to do he has pics of everything you will need.
