2014 EZGO gas golf cart with Kawasaki engine. The the hose to the crankcase has good impulse. The line to the carburetor has good pressure or feels like it does anyway. But no fuel is reaching the pump I think. I can't see any fuel in the filter which is right before the pump. Tank tube is not cracked. I cranked the engine and see no fuel filling the filter. Bad fuel pump? Any help is appreciated.
