BAP installed, I have a question

[SVTCruz]

So I installed the 20amp BAP. I have a few questions:

1) Do I need to install the vacuum switch? I read online a lot of people avoid this, but didn't find why they do.

2) My tuner said I didn't have to upgrade my fuel pump fuse but I read online that I do. Do I need to?

No vacuum pump needed. Just wire the leads together. As for the fuse, if you are running a 20amp then make sure there is a 20amp fuse in. I am running a 40amp and replaced my fuse with a 30.

Cool thanks. Where is that fuse located?
