Severe fuel leak from somewhere behind and below #1&3 carbs?

My apologies. I did not read through all the posts carefully enough and overlooked 98valk, who provided good advice about stopping a fuel leak from the right-side bank of carbs. Thank you, 98valk!
Thanks for the advice about tightening the nuts on the carburetor thru-bolts. That worked like a charm. The two front, interior nuts were difficult to reach as I do not own a long 10mm box wrench. I followed your instructions to the letter, and it worked like a champ!
That's what I love about this forum. So much experience and knowledge out there.
Best regards to all who read and participate in this forum,

I would order new O-Rings, it may have stopped or slowed it for now but that's just because you are jamming the metal in tighter. The o rings dry and get flat and brittle over 20+ years of ethanol fuel exposure. As long as the fuel rail o ring is in its place on the carb and the o ring is bigger than the fuel rail, it wont leak.

""brittle over 20+ years of ethanol fuel exposure. ""
not true at all. buna-n is designed for at least 15% ethanol, it doesn't affect the o-rings. plus Honda uses a higher grade of buna-n.
using wrong fuel additives will degrade buna-n. temperatures over 250F will degrade it.
where is your study documenting buna-n o-rings get brittle at 20 yrs??
I have not found an engineering manufacture that will state what u just did.

Scientific study or not, the fuel rail packing I've replaced were cracked or even crumbling. Doesn't matter why, they needed replaced. Sometimes $hit just happens.

it does matter why they needed to be replaced, cause and effect.
buna-n aka nitrile does not like solvents that are in many aftermarket fuel additives. Honda rates their o-rings for 10% ethanol fuel.

Yeah theres only one member on this board that continues to give terrible advice about these 20+ year old o rings. I rebuilt all six of my carbs and replaced every o ring after they started leaking soon after I purchased my bike last year. Last thing I want to fool around with is gas leaking. Most if not all the o rings were flat, dry and broke easily. Even tires have an expiration date, they get dry rot and crack because rubber does not last forever, then you add ethanol to the mix. I cation anyone with a fuel leak to not take poor advice and try cheap fixes, if you're leaking fuel, rebuild your carbs and replace the o rings. I posted videos on youtube for anyone that wants to do it themselves. I understand the want to try and save time and money with cheap fixes but once you start leaking the o rings will not repair them selves no matter what magic you try, just replace them and you'll be good for another 20+ years.
