Do i Need these??

[y.e.s.drift]

so i recently got my first sr and its great, well at least it looks awesome lol. well i came across on a question/problem. do i need these things numbered on the pic. ive lookd at some pics of swaps on hear i see that some have and some dont and the ones that dont i see still have a hose runnin somewhere to the back of the motor. so im wonderin if i take them off wats goin to happen or should i jsut keep them on.

if im a little unclear excuse me. but any info on it will be greatly appreciated.

Thanks,Daniel

Definately dont need 1. But you can keep 2 and 3, if you decide to get rid of them be sure to put a hose between the T and the port on the block.
