Hello I believe I have a 74-76 rupp nitro 340. I am not getting fuel to the carburetor and believe it is the fuel pump because fuel is not getting to the pump. I took the pump apart and it was filled with bad fuel and clumps. My fuel pump says it’s a nikuni and has a 55 on top. No part number. Please let me know what pump this is and where I can find a new pump or rebuild kit. I will try to attach photos. Thanks
