Err someone mentioned something about clogged fuel filter and excess pressure in the tank. I'm been running a z32 tt fuel filter for the longest time. Dunno if that makes a difference or not either. Maybe less prone to clogging vs oem 240sx-sized fuel filter. I dunno, just throwing some ideas out there.

no relation, the z32 fuel filter makes no fucking difference. and technically, the tank does not crack - it just weeps. pinholes appear at the seam-weld, simple as that.

that link is horse shit. our cars dont just automatically become exempt. they will always have to comply with the applicable smog rules set for our cars.

have you dolts looked at a stock tank? its a very odd, saddle-bag shape designed to hug the underbelly of the chassis. making one out of metal is totally out of the picture. the only solution is fuel cell, period.

here we go again, the magic and mystery of the kouki. its the same fucking tank, no difference.

who told you this? i think you are wrong.

the only issue that is big here, is that the tank doesnt just hold fuel, it also holds the pressure unit needed for obd2 functionality. this is in the later tanks, its actually molded into the tank.

as these cars get older, the only solution will be fuel cell... or convert your car to electric.

ive already posted on this problem years ago, i was able to fix this issue by heating the tank (empty, of course) with a heat gun - and then basically melting nylon (from zip ties or somewhere else) and just plastic welding the two together. it works surprisingly well. however, my car is no longer compliant as i ditched the charcoal canister/evap system - the tank is no longer being pressurized as it originally was. i still have the flip valve, so it holds fumes... just not the same amount of pressure as originally designed.
