Gas tank insanity-please help!!!
It wasn't raining here in OK, so I decided to pull my sender unit this weekend and install the new float I got from LMC Truck. (old float is full of gas). Well, that is when the fun statred.
After puting everything back together, with 1/2 tank it still said empty. So I took it apart again and checked that the electrical part of the sender still works, and with the help of some aligator clip leads, it does, even reads 1/2 with the float at the 1/2 point. Well, to make all this short, my float floats if I tie a string to it and drop it in the tank, but if I attach it to the sender lever, it sinks. The lever moves very freely (it is supposed to, right?), no binds, nothing. I even wire brished all the rust off of it hoping to make it light enough, but it still won't float in gas. It will float properly in water, but not in gas. (gas is less dense than water) Has anybody had this problem? Maybe LMC's float isn't big enough/too heavy?

Re: Gas tank insanity-please help!!!
Thanks guys!!!!
Well, last night on a hunch I though I'd try something else. So, ahem, I decidied to do what I should have done in the first place- find where the float is leaking and solder it back up. So, I found a split in the end, opened it up a bit to get all the gas out, cleaned it, let it dry good, and soldered it. After sticking everything back together, I was really suprized (and delighted) that it once again floated. Now just to see how long the repair lasts..... As for the LMC float: I can't see how any of them could work. They are slightly smaller than the originals, and made of much thicker brass. You can very easily dent the paper-thin brass stock float. The LMC float is just too heavy. Has anyone had any experience with the floats from GMC Paul's?
