G8 fuel pressure

Brandon h · 10-30-2020, 06:38 PM

My g8 has new fuel line and won’t rev up completely. Cleaned carb it is not it, but the fuel pump is not pumping much. It is new. It pumps more than enough but not much pressure. Roughly how much pressure should the pump have. I think this is the problem but not too sure. Thank you!

With my stocker I just cranked the engine and with the fuel line off the carb looked for a good amount with each pulse into a safe container. Usually a bad pump will show in this test. You don't mention the pulse lines condition. It needs not to collapse in use and fit tight on both ends.
