been helping out a few people in some FB groups i attend and thought i would post it here as well in case it may help someone.
fuel tanks for the MGTs are getting rarer and harder and harder to find, and sometimes leak from around the pressure nipple on the tank. this more started as just a temp fix, but just kept working and kind of forgot till recently that i had done it.
first start with pulling the pressure nipple slowly out.
from here you are going to remove the clunk system line.
(i honestly would recommend to replace the clunk system line while you are here, but it can be a PITA fishing it around, if you aren't going to, take care to not cut or poke the fuel line).
try to keep it accessible, i used the fuel tank primer nipple so it didnt fall into the tank.
then find an o-ring with a diameter close to the diameter of the narrower section of the nipple (above the flare).
note: this shouldn't see much fuel, so nitrile rubber may be ok to use here, but id recommend nitromethane and methanol resistant o-rings.
then from here use some sort of ARO or fuel to allow the nipple to slide in easier and re-insert it.
should look something like this.
it should pull the nipple flare up to more tightly seal around the inside of the grommet.
Hope that helps!
keep burning nitro.
