gas capacity

[hf240z]

i was having a problem with gas smell a few months back, So i replace all the hoses. doing this, gives me another problem, the fuel gauge go only up to half tank and i can only put 5 gallons of gas, i am wondering what could have gone wrong when i replace the hoses?

question 2. do i need a rear sway bar on my 1972 240z? if i do need it , can i use one from a later model 240z?

Good question. Are you sure the tank is venting? When you put 5 gallons in, is the tank full (does the pump cut off) and if the tank is not completely full, how far have you tried to drive it with what is in the tank.

The fuel gauge could be wrong, or the tank is not venting correctly and will not allow the trapped air to escape and allow you to fill the tank.

A rear swaybar is not a necessity, but it will improve your handling depending on how you drive. A later 240 bar will work, it all depends on if your car has the swaybar mount brackets in front of the rear suspension or not. If they are there you will need a later model bar, if not you may need to use an early style bar that mounts behind the suspension on the rear crossmember.

thanks, it might not be venting period because i use a regular hose without a bend to go with the direction of the pipe coming out of the tank, and when i pulled the rubber to reach the vapor tank (or something at the back of the car), i might have kink the hose, hence, vent is block... i will connect somemore hose at the end to give it some more slack.

thank you so much,
