After filling up with gas my 81 US stalls on first start up at the gas station - about 75% of the time. Restarts immediately and runs fine until next fill up. A few months ago I replaced the hoses and wye connector at the canister in the R/F wheel wheel. Thanks to a recent stall on the highway, the fuel pump, fuel filter and check valve are also new. The car has done this since the day I drove it home last July. Not a big deal but I'm curious if there is a problem lurking. Thanks, Tom
