Question
not pumping gas upto engines ihave to pour gas in carb tokeep runing

Answer
turn on your key and under by your gas tank you should hear a small buzzing sound onn drivers side that is where your fuel pump is located, it is either your fuel pump or relay is bad you will need to jump the wires on your FPR it should be by the firewall (google fuel pump relay or go to ebay) I believe #87 and the one directly across it towads the firewall you jump. (There will be 6 pins or so look at the bottom of it # 87 and something acrosee from it make a jumper wire to verify your pump is working or not) you will hear fuel rushing into your system and a buzzing. If not when you hard jumped your FPR your pump is bad and will need to order new one probably change fuel filter too since it comes in a collapsable unit. The fuel pump is on drivers side right before or behind the back wheel its under a plastic shroud.
