Zex nitrous question

[98-BLKGT]

instructions are a lil vague. this is a zex dry shot going on my 98 with a 4.6. the 1 vac line coming off the zex box says it goes to the FP regulator. ok fine, but theres no extra port, do i just "T" it in the existing hose? if so which 1, the vac line or the fuel supply line? same goes for the manifold vac line. do i just "T" it in? or is there a capped off port im missing?

i believe you remove the vacuum line from the regulator, cap it/plug it off, and run the zex vacuum line to the fp regulator
