Methanol bms stealth tank set up question

[Pussiwillow]

Hello, I have an f30 but maybe more traffic for this here as it shouldn't change much.
I have a bms stealth tank and am in the process of piecing the kit together, I'm going with braided lines for the set up and cannot modify length once received, and I don't want to make my own if I don't need to. Snow performance has a trunk mount kit with a 15' line, certainly that's too long, anyone here do a trunk mount set up with braided lines, or even soft line but know the exact length? I'm thinking 10 feet is pretty close to what I need. Any input would be appreciated, I'll be around the car tomorrow and I can mock with string I guess but figured i would ask as my time is limited this week.
