    !/4 tank stalling

    i just bought an sc. really pleased so fart, but today, at 1/4 tang it acted like it was out of gas. i limped to a station and, sure enough the car ran fine aftert i added some. i believe the level float and pump are on the same mechanism so i am guessing it is out of calibration. my question is, what else could it be? it almost seemed like a throttle position sensor for awhile. any help is appreciated.

    Sounds like a bad sending unit - had one in my 87 Feiro and just made the best of it because its not worth dropping the gas tank for a minor annoyance. If you know that 1/4 tank is acutally empty, just plan for it.

    My 89 bird will do the same thing at a half tank. I know that the sender is alright. It seems to be more of a problem in the summer while its warm outside. I can usually get down to a quarter tank once the temp outside drops below sixty. Ive replace the filter and checked fuel press. The stall dosn't have to happen at any particular time either. (ex hard acceleration or just hyw crusing). It almost feels like a electrical stall but the problem instantly goes away once the tank is full. Anyone else have this problem??

    could be vapor lock? .....or look into a new fuel pump.
