Well im a newbee to this site.... but i got an 81 gmc sierra and im not gettin fuel to the carb just put new carb, sending unit and fuel pump SOMEONE HELP

check the inline filter, if you have one.

the in line filter is good

crank the engine over a bit, then take off the fuel line where it bolts to the fuel pump, should get a little dribble of gas out of there at least! If you are, then it is your pump. Are you absolutely sure you arent getting fuel or is it just not firing? I have a visible element inline to my carb that lets me know positively that im getting fuel - a good investment IMO

i know for sure im not getting any fuel because i took the line off and cranked it over and Nothing at all came out but could the fuel pump just have gone on it

not likely, they are mechanical and last forever. It could have gotten clogged if something got into the line when you changed the sending unit. Also, make sure if you have rubber lines anywhere, like from the sending unit to the fuel lines that they are not crimped that happend to me for the vent lines.

just change the pump again.

My fuel pump is fine i think it might be the lines
