ugh.. hpop reservoir leaking overtightened?

[dt23400]

installed adrenaline hpop last week. it was great. then last night i parked it and went out there earlier today and saw the oil. started it up popped the hood. and bam there it is. leaking from where it looks like under the bolt. well i guess i overtightened it. should have read the directions. so i cant find anywhere on how to fix this. ive looked for like 3 hours straight. do i just need to order a new one? what can i do? need the truck asap. thanks guys.
