Not sure if you used silicone or not but I always have and never had a leak and I just tighten them hand tight. Just make sure you inspect the bulkhead first because small bumpy casting flaws can cause problems if you don't take them off with a utility knife first.

for years i just snug them up and coat the heck out of them with sillicone, and just expect that it will be a pain if they ever have to get removed

[o.c.d.]

I feel your pain. Been there, done that. Sucks bad. I too silicone them up now.
