What Does The "jet Pump" Actually Do?

[Hanaldo]

By the way, I imagine given your setup you are probably planning on changing all the lines anyway, but just to let you know in case you go through the same headache I'm going through now;

The standard fuel lines going to the fittings on the fuel lid are NOT push on hose. It is not as simple as replacing the fittings in the lid with AN barbed fittings and pushing the old hose on. They are plastic hard lines, so designed to be one piece with the fitting. Hence why they use those special fittings rather than standard barbed ends and a hose clamp. This would be fine if it was a simple job to replace those hoses, but it really isn't. It's impossible without removing the fuel tank. I'm now going to run a new fuel line and ditch the factory hard line.
