sc400 nitrous fuel line taping help.
i want to tap my fuel line without damaging it.
my zex nitrous kit has a female -4an hose that needs to connect to the fuel line.
does anyone know what to call the threads were the fuel line comes apart in the engine bay?
i think its m14? i measured the male fitting od 14mm and the treads at 1.5 there flared fitting like brake lines.
is there a tee that would fit this to tee off to a -4n male? a tee would have to have a swivel on the male end going into the fuel line that goes to the fuel rail. not sure if thous fittings with o rings would work?
i seen one photo where they use a new banjo fitting on the fuel pressure reg.
i just don't want to hack it like that one photo where they cut the fuel line in half then tee off it.

Hey I think the t line connector you were talking about was my car. The nitrous system worked great the way it was installed and fuel never leaked. I had the nitrous system on for two years. Only sold it because I needed money at the time to move across the country.
Enjoy your nitrous system, make sure to install the transgo shift kit.

i bought a honda fuel pressure adaptor, banjo bolt m12 with a 1/8 NPT hole on top.
then i got a 1/8 NPT to -3an adaptor to screw into the banjo bolt.
i removed the stock banjo bolt from the driver side fuel rail (m12) and put in the adaptor.
no cutting the fuel line here.
i had to make a bracket to mount the zex controller.
not sure if it was a good idea to mount it on top of the engine do to heat?
i been dealing with a defective nitrous express bottle dated 6/12.
it keeps leaking around the valve seal, i was told my valve was bad so i got a new one,
but it leaked also. after several returns to the race shop abc fire fixed it with 2 modified seals.
they would torque the valve down but it was not smashing the seal? defective bottle.
nitrous express was no help, i would not buy from them ever.
i could of bought 2 new bottles for all the wasted nox and costs of valve, trips to the shop ect ect..
i am looking into a rpm switch for 50 bucks at jegs.com

i forgot to add i used a small coper wire that i striped about 1.5 inches off and stuffed it
in the tps tap then put the plug on. so i did not cut/hack/damage or attach anything to the wires on the tps
switch. ill post a better photo on my fuel tap for the zex kit soon.
for the 3 tests i did 2 on 75 hp one on 100 hp they seem the same? but i wait till I'm going over 40
waiting for a rpm switch then ill try off the line.
