  • S14 Gas float becomes unlodged

    I don't know if anyone else has experienced this but it seems my gas float comes unlodged about once a year. Kind of a pain to open it up and clip it back in place.

    Anyone have any more permanent solutions? Once I clip it in place, I can't shake it loose with my hand. Maybe the big sticky race tires and violent nature of autocross and track days is what does it.

    I remember mine had become dislodged when I first bought the car, but I haven't had any problems from the many autoX and road racing sessions I have experienced. I'm actually going to inspect my pump and other misc fuel components, so I'll let you know if I see anything that could cause it to come loose.

          Had it happen on both 14's I've owned now.
          My fix was to bend the tab towards the wall of the tank making it wedge when you put the float back on.
          So far both have been fine.
          First one even stayed on through 2 side impacts.

          Both came off from drifting.
          And yes it does suck to do any fuel tank work on a 14 :-/

          From what I've noticed it happens from having that right amount of fueal that when it sloches around it knocks the float off.
          Around the 1/2 tank mark I would say.

            Could be why I haven't seen those problems. I usually start a race with about 3/8 tank. It's very rare that I have even 1/2 tank in the car. I might fill up on my way to the track if I plan to run a full practice day before I qualify, but usually I don't get enough track time to burn down the whole tank before qualifying. Thus I just fill up in 5 gal increments.

              For autocross I always start around 3/8ths of a tank. So yeah, that could be the reason.

                I threw a zip tie around mine, but don't remember what it anchored to.

                  Mine falls off all the time. I haven't bothered with it because I don't really drive my car enough to worry about fuel levels. It doesn't need gas to sit in the driveway.

                    For autocross, I watch the fuel levels a bunch. I don't want any extra weight but also don't want to fuel starve and kill my fuel pump. Plus it is annoying to be driving down the street showing 1/2 a tank and then all of sudden the needle is on empty. Not to mention all that is holding the float in at that point are wires that could easily break when it flops around.

                    Sucks the car is just sitting in the driveway though.

                      pretty sure mine came off this past track weekend or the one before it. always reads full now and occasionally dips a bit when it feels like it. i'll probably have a go at reattaching it this weekend and hopefully find a ziptie-able spot in the tank. yay to smelling like gas again.

                        There's no room for a zip tie and I'm sure the gas would just eat away at it.
                        Only solution I have come to is bending the tab the float sits on so it wedges the floats tab between the tank and the retainer tab.

                          bah, yea i just re-hung it and didn't zip tie it.

                          i think there might be room to zip tie it to the hanger itself, but i was pretty fed up with submerging my arm almost elbow deep into the gas just to get it back on the hanger. ended up not experimenting and putting it back on the way it was. next time it comes off i'll make sure i have less gas in there before i do the job. i thought i drove enough miles on this tank to lower the gas level enough... apparently not. bending the tab sounds like an option too. i can imagine it being hard to thread a zip tie with one hand

                          in terms of durability in gas, zip ties should be ok. i have one or two that have been submerged for a few years supporting the fuel pump in addition to a metal worm clamp. last i checked it was still tight. prboably not easy to get it in there and actually holding the float though.

                            Reviving an old thread since I am doing this right now... Just washed the gass off my hand. I can't for the life of me figure out where/how this thing clips on, does it slide on from the top? From the leftist? From the right? I can see some of the clip in the tank but not all of it, thanks to contorting myself into the trunk. I can't see how it goes on and can't find a picture of the actual clip anywhere either.

                            I see the float has two "slots" that appear to allow something to slide through it sideways but I can't figure out what to slide through there... :S

                            Can anyone fill me in?

                            This thread seems to show the float sliding on from the top but that is contrary to what i see when I look at the float...

                              FWIW, I don't think nylon is affected by gasoline or ethanol. So a zip tie should last for quite a long time.

                              That said, you can always use a stainless steel worm drive hose clamp.
