Hi everyone I'm currently restoring a '75 280z and am running into some problems with cleaning the gas tank. I've tried cleaning it with acetone and some bb's but for some reason I believe the fuel hose outlet is still clogged. Ive tried compressed air and pouring acetone directly into the pipe but cannot seem to get anything through it. This is my first restoration and Im faily new to the whole process is there any suggestions sort of taking it to a radiator shop or buying a new tank that I could try. Thanks!
