I need urgent help

Hello, greeting, my problem is this, I have a Hyundai Elantra 2000 Tourism, I was excellent, suddenly I began to have a problem with the gas tank, the gasoline returned, it took it to the mechanic and dismantled it to review it, I had nothing strange, they with the eagerness to fix that problem, they took away some like seeds that I carry in the tank that are for the absorption of the steam of gasoline. The problem was arranged, gasoline and everything enters. Now another problem turned out, it goes out ... even if it takes it to 80 or 100 km, by removing the foot from the accelerator it feels like it is locked, when putting the cluch goes out. They do not know what can be, Le Canbie Candelas, Filter of gasoline, clean injectors and the EFI system and nothing ..
I have spent enough money and I can't get this problem solved. Please help me, thank you for taking your time reading this.

I believe that some conservative of the pump can be affected, but if they did a job in the pond they must first check that part since it has the round and return flow hoses, in addition to the fact that the pump has electrical connectors and can unintentionally damaged any damaged damage in the pump, so you say that I think the pump cuts the fuel flow, check and warning.

That such a friend,
I agree with our friend reviews the return of gasoline, both the full line can be done with the stop car and checks, also the pump that has the appropriate pressure a low pressure produces fails.

hello.
Reading the initial question I have a question that I would like someone to clarify me. I had not heard of those seeds that names that it exists in the fuel tank for the fuel vapors. According to what I know that I do not know if I am correct, it is that there is a system that has these seeds that is the canister filter that is responsible for sending the gases of the tank for cold start taking advantage of them in the operation of the engine. Am I right?

Hello, thank you all for your advice, I am the boy of the Hyundai Elantra 2000, they reviewed what you told me and is fine, it has been removed a little, now it is that when it is half a tank or more of gasoline you are accelerating and you lift a little your foot feels like it will be stood and turned off, but if you are less than half a tank, it does not really give me problems, this car is really a fortune. head.
