I have a mega Lego build but everything's there its a 20r with a weber short bed. Good tank, good pick up screen, was new filter. New lines from hard lines from tank to carb. I had a good working pump on it, no issues for a month then randomly yesterday it was acting like it was out of fuel. I limped it home and put a half tank in it and still same thing starts. Runs. Idles and will drive until it runs low on fuel I look at the fuel filter and its 1/4 full with a steam of air bubbles and fuel coming down. All lines except the hard line. Still getting air in filter. Took gas cap off no difference
Blew out all lines in let, outlet, and vent lines near intake. Loosing interest in a carbed fuel system...... Any ideas
