Fuel pump issues

[stomper]

Try taking the fuel line off the fuel pump that goes to the carb, and see if you have fuel
Coming out there while manually priming the pump. Also see if you can blow air through the fuel line from the fuel pump to the carb. It sounds like you have crud in your fuel lines.

If there is any leakage on the lines or connections from the tank to the fuel pump, the fuel pump will draw in air instead of fuel. If you have the factory fuel tank swapover valve, the cork disc inside the valve can harden or shrink. This could allow air inleakage or not actually isolate the empty tank. The screen on the bottom of the tank pickup tube can become clogged, and I have had a small hole in the pickup tube prevent fuel pickup when the tank level dropped below the hole. If the fuel tank or cap is not vented, the fuel pump can pull a vacuum on the tank preventing fuel flow.

I got it Since in landrover the golden rule to keep fuel in the tank, and I am having two petrol tank, the second got empty and air comes into the lines.

I run the engine by putting some fuel in carb then it run from second try.

Thanks all for help

I am having the same problem, a vapor lock type of thing when after I drive for a while, the SIII won't restart for me. We've put aluminum foil around the hoses, next is to get a new pump, and new fuel filter. I'll add some length to the hoses so they avoid the manifold. Any other suggestions?
thanks!
