Presto

Got a 240sx it’s my first car I’m working on I’m replacing the gas tank which was rusted out again after I tried cleaning the rust the first time, and I just ordered new pump,sending unit, and tank, Previous owner deleted charcoal canister, I’m trying to avoid future rusting of my new parts

These are my options:

1.If I have fuel tank evap nipple>check valve>hard line that runs up To engine bay and cut where I think the charcoal canister might have been (previous owner deleted) + s14 gas cap, am I good on the explosion/implosion/rusting?

2.What if I removed the check valve, capped the line from the evap nipple and buy an s14 gas cap? Am I risking rust and issues still?

3.Can I run a hose from the evap nipple to a filter like in this thread, and buy an s14 gas cap? Or would this let moisture and things into the tank?

I’m just confused but please help me if no one replies I’ll probably just go with option 1 or 2 and hope I don’t blow up or waste $1000
