92 corolla keep stalling

my 92 corolla recently got a gas tank replaced now when i drive my car it shutdown on me i belive it has something to do with the gas so i went and brought a relay, but i'm still having this stalling problem so what should i do? drain out my old gas than buy some treatment than buy clean gas? Or should i buy a new fuel filter? please some one help me i'm tried of catching the bus when i have a car at home the need a little work done to it thanks.

it should either be the fuel filter or the fuel pump. Easiest thing to try would be the fuel filter, as most fuel pumps are in the gas tank. Did they replace the fuel pump when they replaced the tank? if so, did they put the right one in it?

take the fuel line off at the filter and have sum 1 crank the engine and see if the specified amout of fuel somes out in the cranking time and if its adaquite its prob something else that happened to go at the same time or something in the fuel line after the filter is clogged
