nitrous fuel line tap help

[mtd2198]

i need help with my zex nitrous set up.
i do not want to cut my stock fuel line.
i been trying to find a tee that will fit where the fuel line comes apart.
i measured the fuel line treads as metric 1.00 and 13mm
the nitrous has a -4an hose.
what can i use to tee off the stock fuel line where it comes apart?
i have no idea what that metric fuel line male to female treads are called?
or what brass tee would fit in there?
a male to female to -an4 tee that fits the sc400?
is there a double banjo bolt that i can tap off the fuel rail?
the only photo i seen on fuel tap is someone cut there fuel line in half with brass fittings. looks so easy yet so hard to find the tee.

fuel pressure gauge adapter?

looks like i might have found the best way to tap the fuel line.
i found a honda fuel gauge adapter banjo bolt that has a 1/8 NPT hole right
on top. its a M12x1.25 banjo bolt with a 1/8 NTP hole for a pressure gauge.
ill remove the driver side banjo bolt on the back fuel rail then ill put the new one
in with the 1/8 NPT x -04an male fitting attached to it.
seems simple and there is no damage to the stock fuel line.
M12 X 1.25 X 1/8NPT $10.00
1/8 NPT X -04AN male $6.00
ill post photos when I'm done waiting on parts now.

i can't tell much from going from 75 to 100 shot but
zex has me using 46n/30f and 40n/26f jet sizes but i think the 43n/26f
would be better at around 85 hp but leaner then the 75 hp jets.
not sure why zex uses bigger fuel jets then the rest?
