replacing a fuel pump is not trivial. Why do you think it is not working correctly?

 

In first gear it stutters when i give it lots of gas when i give it a little it dont stutter

 

In your signature, you have 22r which is carbed, it is on the front of the motor. Fuel injection, 22re, is in tank. I wouldnt suspect the pump but carburator myself from your last comments. I dont know carbs as well so could be wrong.

Carbed pump.

 

Thanks. I have another carb that im going to cleaned .
